Full DMV Practice Test - DRIVING INSTRUCTOR CA

Practice Test #1

Test your complete DMV knowledge with one full-length practice exam covering signs, laws, and safety — all in a single comprehensive quiz. The test includes 36 questions, and you must answer 30 correctly to pass.

1 / 36

What should you do if you realize too late that you are about to miss your turn or exit?

Keep driving until you can safely and legally turn around

Turn sharply into the exit lane before reaching the sign

Make a quick lane change if there is a small gap

Stop immediately and back up carefully

💡 Explanation: Never make sudden lane changes or last-second turns. If you miss your turn or exit, keep driving straight until it’s safe to turn around. Abrupt changes increase the risk of collisions with nearby vehicles.

2 / 36

In California, when are traffic fines automatically doubled?

In Safety Enhanced-Double Fine Zones and highway work zones when workers are present

During heavy traffic on major freeways

Only in city street construction areas

Only at night in active maintenance areas

💡 Explanation: California law (CVC §42010) doubles traffic fines in Safety Enhanced-Double Fine Zones and in highway construction or maintenance zones when workers are present. These areas are marked due to increased collision risks and worker exposure.

3 / 36

According to California Vehicle Code §22454, when are you not legally required to stop for a school bus with flashing red lights?

When driving under 25 mph near a school zone

When the bus is on the opposite side of a divided highway or a multi-lane road with two or more lanes in each direction

When the bus driver waves you through

When no children are visible near the bus

💡 Explanation: Under California Vehicle Code §22454, every driver must stop when a school bus displays flashing red lights and an extended stop arm — from either direction — until the lights stop.
The only exceptions are when the bus is on the opposite side of a raised divider, wall, or median, or when you’re separated by a multi-lane highway with two or more lanes in each direction.
In all other cases, you must stop completely, regardless of speed, visibility, or whether children are seen.

4 / 36

When exiting a highway, what should you do if you realize you’re in the wrong lane?

Slow down sharply and try to merge anyway

Continue to the next exit safely

Stop on the shoulder and back up to the exit

Cross solid lines quickly to make your exit

💡 Explanation: Never cross solid lines or stop on the highway to reach an exit. If you miss your exit, stay calm and take the next one. Re-enter the highway safely if needed.

5 / 36

What does a diagonal crossing signal allow pedestrians to do?

Cross only to the opposite corner and wait for the next WALK signal before proceeding further.

Cross only straight across the street, not diagonally.

Cross diagonally at any time if the road is clear.

Cross in any direction — including diagonally — when the WALK signal appears.

💡 Explanation: Diagonal or “scramble” crossings allow pedestrians to cross in all directions, including diagonally, when the WALK signal is displayed. Pedestrians must wait for the WALK indication before entering the intersection and always remain alert for turning vehicles.

6 / 36

When facing a solid red traffic light, when are you allowed to turn right?

After stopping completely, yielding to pedestrians and traffic, and if there is no “NO TURN ON RED” sign posted.

Anytime, as long as traffic is light.

Only if the intersection is clear and there are no pedestrians, even without stopping.

Only when a police officer waves you through.

💡 Explanation: A solid red light means stop. In California, you may turn right after stopping fully and ensuring it’s safe, unless a sign specifically prohibits it. Always check for pedestrians and oncoming traffic before turning.

7 / 36

Which of the following individuals is eligible for a no-fee Senior ID card from the California DMV?

Only individuals receiving government assistance

Only seniors who surrender their driver’s license due to a medical condition

Any California resident age 62 or older

Any driver 55 or older who completes the Mature Driver Program

💡 Explanation: California offers a no-fee Senior ID card to all residents aged 62 or older. Additionally, drivers of any age who can no longer drive safely for medical or cognitive reasons may voluntarily exchange their driver’s license for a no-fee ID card, but the automatic age-based eligibility begins at 62.

8 / 36

You see livestock or horses near the road and a person signaling you to slow down. What should you do?

Flash your headlights to warn the animals

Maintain your speed unless they block your lane

Slow down or stop and follow the person’s directions

Honk to make the animals move away

💡 Explanation: If animals or livestock are on or near the road, slow down or stop until it is safe to proceed. Always follow instructions from the person handling the animals and avoid honking or sudden movements that could startle them.

9 / 36

Under California law, when may a minor legally use a cell phone while driving?

Only to respond to texts from a parent

Anytime if the phone is mounted

Only for emergency assistance

Only when using hands-free mode

💡 Explanation: Minors are prohibited from using any electronic wireless device while driving unless making an emergency call, such as reporting a collision or calling for help.

10 / 36

When making a U-turn in a residential district, how far must approaching vehicles be before it’s legal to turn?

At least 200 feet away

At least 250 feet away

At least 100 feet away

At least 150 feet away

💡 Explanation: In a residential area, you may make a U-turn only if no vehicles are approaching within 200 feet in either direction. This ensures you have enough space and visibility to complete the turn safely.

11 / 36

When driving near motorcycles, what is the safest way to share the road?

Pass a motorcycle in the same lane if there’s enough room

Follow closely to discourage sudden lane changes

Allow at least a three-second following distance and never pass in the same lane

Drive in the center of your lane to prevent motorcycles from passing

💡 Explanation: Motorcycles are smaller and harder to see, and they can stop or swerve suddenly due to road conditions. Maintain at least a three-second space cushion, never pass in the same lane, and always check your mirrors and blind spots before changing lanes or opening your door near traffic.

12 / 36

When you sell a vehicle in California, what must you do within 5 days?

Transfer the title into the buyer’s name yourself

Submit the vehicle for a smog inspection

Notify DMV by submitting a Notice of Transfer and Release of Liability

Remove the license plates and return them to DMV

💡 Explanation: Sellers must notify DMV within 5 days by filing a Notice of Transfer and Release of Liability (NRL). This protects the seller from future liability such as parking tickets, toll violations, or collisions involving the vehicle after it has been sold.

13 / 36

What is the default speed limit in a California business or residential district when no signs are posted?

15 mph

20 mph

25 mph

30 mph

💡 Explanation: In California, the basic speed limit in business or residential areas is 25 mph unless a different speed is clearly posted. This limit protects pedestrians, cyclists, and vehicles entering or leaving driveways in dense community areas.

14 / 36

Your brake lights just failed. How do you signal that you’re slowing or stopping?

Extend your left arm straight out horizontally

Extend your right arm downward toward the road

Raise your left arm upward at a right angle

Extend your left arm out and bend it downward at a right angle, palm facing toward the rear

💡 Explanation: To show a slow or stop with hand signals, put your left arm out the window, bend the elbow downward to about 90°, and keep your palm facing back so drivers behind you can clearly see the signal.

15 / 36

On a two-lane road, when is it safe to pass while approaching a hill or curve?

Whenever the vehicle ahead is 10 mph under the speed limit

When the center line is broken and no headlights are visible

As soon as oncoming traffic appears far in the distance

Only if you can see at least one-third of a mile of clear roadway ahead

💡 Explanation: Passing near hills or curves is only safe when you have long, clear sight distance. You need at least one-third of a mile of open roadway to be sure no oncoming traffic will appear as you move into the opposing lane.

16 / 36

When parking uphill or downhill on a road without a curb, how should you position your front wheels?

Always away from the road — turn them toward the shoulder.

Keep them parallel to the edge of the road.

Always turn them toward the center of the road.

Keep them straight to avoid tire wear.

💡 Explanation: When there’s no curb, always turn your wheels toward the side of the road. This way, if your vehicle starts to roll, it will move off the roadway instead of into traffic. Always set the parking brake and leave the car in park or in gear.

17 / 36

Where should you stop your vehicle before making a right turn at an intersection with no limit line?

Before entering the crosswalk

In the middle of the intersection

Directly in the crosswalk

At the edge of the intersection

💡 Explanation: If there’s no limit line, stop before the crosswalk to allow pedestrians to cross safely. If there’s no crosswalk, stop before entering the intersection.

18 / 36

When are you allowed to pass another vehicle on a two-way road with a broken yellow line?

Only when the broken yellow line is next to your lane and it’s safe to do so

When both sides of the road have solid lines

Only on hills or curves

Whenever traffic ahead is slower

💡 Explanation: A broken yellow line next to your lane means you may pass, but only when you have enough space and visibility to do it safely. If the solid line is on your side, you cannot pass.

19 / 36

Who can be cited if a 15-year-old passenger is not wearing a seat belt?

Both the passenger and the driver

Only the driver

Only the passenger

No one, if the car is moving slowly

💡 Explanation: California law holds the driver responsible for ensuring passengers under 16 wear seat belts. Passengers aged 16 and older are responsible for themselves.

20 / 36

Parking on the wrong side of the street or on a freeway is generally illegal. In which situations is it allowed in California?

Where a stop is specifically permitted by signs.

During an emergency.

All options are correct.

When a law enforcement officer requires a stop.

💡 Explanation: Parking on the wrong side of the street or on a freeway is not allowed except in specific cases — during an emergency, when directed by law enforcement, or where signs clearly permit stopping. In those situations, you must still park completely off the roadway and remain in your vehicle until it is safe to proceed.

21 / 36

You are driving on the freeway at 55 mph and decide to move in front of a large truck. What should you keep in mind before merging?

Large trucks take much longer to stop, so avoid cutting in front of them

Trucks slow down faster because of their weight

The truck can stop just as quickly as a car if it has new brakes

The truck driver can see your car clearly even if you merge closely

💡 Explanation: A fully loaded truck traveling at 55 mph can take up to 400 feet to stop — much longer than a passenger car. Always leave extra space when merging ahead of a large vehicle, and never slow down suddenly after moving in front of one.

22 / 36

A 16-year-old with a provisional license needs to drive their 12-year-old sister home at 7:30 p.m. because the parent is working and no other ride is available. What must the teen carry to make this trip allowed under the family exception?

A text message from the parent saying “OK”

A letter from the DMV appointment system

A signed note from a parent or guardian that explains the reason, names the family member, and states when this need will end

A note from the school coach approving the ride

💡 Explanation: The family-member exception lets a provisional driver transport an immediate family member only if they carry a signed parent/guardian note that gives the reason for driving, identifies the family member, and lists when the situation will end.

23 / 36

When merging onto a California highway, who has the right-of-way?

The larger or faster vehicle

The vehicle entering from the on-ramp

Whichever driver signals first

The vehicles already traveling on the highway

💡 Explanation: Highway traffic has the right-of-way. Drivers entering from an on-ramp must wait for a safe opening before merging, without forcing other drivers to brake or change lanes suddenly.

24 / 36

What does California’s “three-second rule” help drivers maintain?

Correct braking pressure

Proper lane position

Adequate space for merging traffic

A safe following distance behind the vehicle ahead

💡 Explanation: Choose a fixed point the car ahead passes, then count “one-thousand-one, one-thousand-two, one-thousand-three.” Your vehicle should reach that point no sooner than three seconds later. Increase distance in poor conditions or at higher speeds.

25 / 36

You see a white square sign with a red circle and slash over the image of a U-turn. What must you do?

Make the U-turn only when no other vehicles are visible.

Stop before starting the U-turn, then proceed carefully.

You are prohibited from making a U-turn at this location.

Continue the U-turn if it looks safe.

💡 Explanation: A white regulatory sign with a red circle and slash means the action depicted is banned. In this case the U-turn symbol is crossed out, so U-turns are not permitted at that location.

26 / 36

After driving through deep water, your brakes feel weak or spongy. What can you do to restore normal braking?

Apply the emergency brake repeatedly to dry them

Lightly press the accelerator and brake pedals at the same time until normal braking returns

Continue driving and wait for them to dry naturally

Stop immediately and call for assistance

💡 Explanation: Lightly applying both pedals generates heat and helps dry wet brake components. Continue this process only until normal braking response returns, then resume regular driving.

27 / 36

You approach a T-intersection without any stop or yield signs. Who has the right-of-way?

The vehicle on the road that ends

The vehicle that arrives first

The vehicle on the right

The vehicle on the through road

💡 Explanation: At a T-intersection without stop or yield signs, traffic on the through road (the one continuing straight) has the right-of-way. Vehicles entering from the road that ends must yield to traffic already traveling on the through road.

28 / 36

What does a flashing yellow arrow indicate?

Stop completely before turning left.

You may not turn until the light turns green.

The protected left turn has started — you have the right-of-way.

You may turn left, but you must first yield to oncoming traffic and pedestrians.

💡 Explanation: A flashing yellow arrow means you may turn left, but the turn is not protected. Oncoming traffic has a green light, so you must yield to vehicles and pedestrians before turning. Proceed carefully and make your turn only when it is safe.

29 / 36

What is required if your vehicle strikes a parked car and you cannot locate the owner?

Leave immediately since no one was injured

Drive home and report it later if the damage is serious

Call your insurance company and take no further action

Leave a note with your contact information and report the collision to law enforcement

💡 Explanation: California law requires drivers to leave a written note with their name, address, and phone number and to report the collision to law enforcement when hitting unattended property. Failing to do so constitutes a hit-and-run.

30 / 36

Which type of driver’s license do most California drivers need to operate a regular car for personal use?

Commercial Class A license

Noncommercial Class C license

Motorcycle Class M license

Temporary learner’s permit

💡 Explanation: Most California drivers use a noncommercial Class C license to operate regular passenger vehicles. Other vehicle types, such as motorcycles or large commercial trucks, require a different license class.

31 / 36

When is it legal for a driver to enter or drive in a bicycle lane?

To pass slower traffic

When traffic in other lanes is congested

When parking (if permitted), entering or leaving the roadway, or turning within 200 feet of an intersection

Only when no bicyclists are present

💡 Explanation: It is illegal to drive in a bicycle lane except when parking, entering or exiting the road, or turning within 200 feet of an intersection. Always check for bicyclists before entering the lane and yield to them.

32 / 36

How should bicyclists make left or right turns?

By signaling only when a vehicle is directly behind them

By using hand signals and following the same turning rules as drivers

By dismounting and walking the bicycle across the intersection

They may turn any way that feels safest

💡 Explanation: Bicyclists must use hand signals and follow the same turning rules as vehicle drivers, using either the turn lane or crosswalk as appropriate. This ensures predictable movement and allows drivers to anticipate the bicyclist’s actions.

33 / 36

Which of the following statements about headlight use is true?

It’s okay to drive using only parking lights during dawn or dusk

You should use headlights on mountain roads and in tunnels, even during the day

High beams should always be used in fog for better visibility

You don’t need headlights when the sun is low on the horizon

💡 Explanation: Headlights improve visibility and help other drivers see you, even in daylight conditions such as tunnels, mountain roads, or when the sun is low. It is illegal to drive using only parking lights in California.

34 / 36

Under California law, when must a physician report a patient to the DMV?

When the patient fails a routine vision test

When the patient requests a driving clearance

Only if the patient has a contagious illness

When the patient has a medical condition that may cause loss of consciousness or unsafe driving

💡 Explanation: California doctors are required to report patients age 14 or older who have medical conditions—such as seizures or lapses of consciousness—that could make driving unsafe. The DMV reviews these reports to decide if driving privileges should be limited or suspended.

35 / 36

Another driver signals and begins to pass you. What should you do?

Slow down sharply to give a speed advantage to the other car.

Move slightly into the right lane to give them more space.

Speed up to give them more space.

Stay in your lane and keep a steady speed until they have passed.

💡 Explanation: When another vehicle is passing you, stay in your lane and maintain a steady speed. Do not drift, brake suddenly, or accelerate. Staying predictable helps the passing driver complete their maneuver safely and prevents confusion or collisions.

36 / 36

You and another driver approach a four-way stop from opposite directions at the same time. You plan to turn left, and the other driver plans to go straight. Who should go first?

Either driver, since it’s a four-way stop

The other driver, because vehicles going straight have the right-of-way

You, because you signaled first

You, because left-turning traffic always moves first at stop signs

💡 Explanation: When two vehicles arrive opposite each other at a stop sign at the same time, the driver going straight or turning right has the right-of-way. The left-turning driver must wait until it’s safe to turn.

Your score is

The average score is 79%

Practice Test #2

Test your complete DMV knowledge with one full-length practice exam covering signs, laws, and safety — all in a single comprehensive quiz. The test includes 46 questions, and you must answer 38 correctly to pass.

1 / 46

Which of the following is recognized by California as a common cause of traffic collisions?

A vehicle traveling significantly faster or slower than the flow of traffic

Driving exactly at the posted speed limit at all times

Allowing other vehicles to merge ahead of you

Using turn signals too frequently

💡 Explanation: California identifies several primary collision factors, including unsafe speed, improper turns, right-of-way violations, ignoring traffic signs, and driver distraction. A vehicle moving much faster or much slower than surrounding traffic is a documented risk factor because it forces other drivers to brake, change lanes, or react suddenly.

2 / 46

You and another driver approach a four-way stop from opposite directions at the same time. You plan to turn left, and the other driver plans to go straight. Who should go first?

You, because you signaled first

Either driver, since it’s a four-way stop

The other driver, because vehicles going straight have the right-of-way

You, because left-turning traffic always moves first at stop signs

3 / 46

Parking on the wrong side of the street or on a freeway is generally illegal. In which situations is it allowed in California?

When a law enforcement officer requires a stop.

During an emergency.

All options are correct.

Where a stop is specifically permitted by signs.

4 / 46

When entering a freeway from an on-ramp, which of these actions is unsafe or illegal?

Crossing solid white lines to merge early

Signaling before changing lanes

Merging one lane at a time

Checking mirrors and blind spots

💡 Explanation: Solid white lines mark areas where lane changes are prohibited. Wait until the line becomes broken before merging, and always use mirrors, signals, and quick head checks to ensure the way is clear.

5 / 46

If you are under 21, when is it legal to carry alcohol inside your vehicle?

Anytime, as long as you do not drink it

When the container is open but placed on the floor behind the front seats

When the container is sealed and stored in the trunk while you are driving alone

When the container is full, sealed, unopened, and you are accompanied by someone 21 or older

💡 Explanation: A driver under 21 may only transport alcohol in a vehicle when a person 21 or older is present and the container is full, sealed, and unopened. Open or accessible containers in the passenger area are illegal. Separate exceptions apply when a minor is transporting closed containers as part of lawful employment for a licensed alcohol business, but that does not allow casual carrying of alcohol while driving alone.

6 / 46

You see a white square sign with a red circle and slash over the image of a U-turn. What must you do?

You are prohibited from making a U-turn at this location.

Stop before starting the U-turn, then proceed carefully.

Continue the U-turn if it looks safe.

Make the U-turn only when no other vehicles are visible.

7 / 46

When should you use your high-beam headlights?

In foggy or rainy weather

On open country roads or dark city streets when there is no oncoming traffic

When following another vehicle closely

In heavy traffic to improve visibility

💡 Explanation: High beams improve visibility in dark, open areas. However, you must dim them when another vehicle approaches or when driving in fog or rain, as bright light reflects off moisture and reduces visibility.

8 / 46

You’re temporarily living outside California, and your driver’s license is about to expire. What should you do to stay legally licensed?

Wait until the license fully expires, then apply for a new one

Renew automatically through your insurance company

Keep driving until you return to California

Request a one-year extension from the DMV before your license expires

💡 Explanation: California drivers who are out of state when their license is about to expire can ask the DMV for a one-year extension. The request must be made before the license expires, and limited-term licenses are not eligible for this extension.

9 / 46

If a minor has three at-fault collisions or traffic violation convictions within 12 months, what action does the DMV take?

Probation only

License suspension for one year only

License suspension for six months and probation for one year

A $1,000 fine and mandatory re-examination

💡 Explanation: After three at-fault collisions or violations, DMV will suspend the minor’s license for six months and place them on one year of probation. Additional violations during probation cause another suspension.

10 / 46

What does a green arrow mean?

You may turn in the direction of the arrow; your turn is protected from oncoming traffic.

You may turn, but only after yielding to all oncoming traffic.

You must stop before making the turn.

Oncoming vehicles also have a green light.

💡 Explanation: A green arrow means you have a protected turn in the direction of the arrow. Oncoming vehicles are stopped by a red light, giving you the right-of-way to turn safely. Still, always look for pedestrians or vehicles already in the intersection before completing your turn.

11 / 46

What kinds of drugs or medicines can reduce your ability to drive safely?

Prescription medications

All options are correct

Illegal drugs

Over-the-counter medicines

💡 Explanation: Illegal drugs, prescription drugs, and over-the-counter medicines can all cause drowsiness, slow reactions, or impair judgment. It’s your responsibility to know how any substance affects you before driving.

12 / 46

Why should you keep your front wheels pointed straight while waiting to make a left turn?

It prevents your vehicle from being pushed into oncoming traffic if rear-ended

It helps other drivers see your turn signal more clearly

It keeps your tires from wearing unevenly

It helps you start the turn faster

💡 Explanation: When waiting to make a left turn, keep your front wheels straight. If another vehicle hits you from behind, your car will move straight forward instead of being pushed into oncoming traffic, reducing the risk of a serious collision.

13 / 46

You’re 17 and arriving at the DMV for your behind-the-wheel driving test. Which of the following must you bring to take the test legally?

Any car and your student ID card

Your instruction permit, proof of insurance, and a safe car with a California-licensed driver at least 25 years old

Only your appointment confirmation and glasses

A friend with a learner’s permit and your car’s title

💡 Explanation: Minors must arrive with their instruction permit, a California-licensed driver age 25 or older, and a properly insured, registered, and safe vehicle. These requirements ensure the test is conducted safely and legally.

14 / 46

What does a diagonal crossing signal allow pedestrians to do?

Cross only straight across the street, not diagonally.

Cross only to the opposite corner and wait for the next WALK signal before proceeding further.

Cross in any direction — including diagonally — when the WALK signal appears.

Cross diagonally at any time if the road is clear.

15 / 46

Where should you stop your vehicle before making a right turn at an intersection with no limit line?

In the middle of the intersection

At the edge of the intersection

Before entering the crosswalk

Directly in the crosswalk

💡 Explanation: If there’s no limit line, stop before the crosswalk to allow pedestrians to cross safely. If there’s no crosswalk, stop before entering the intersection.

16 / 46

What requirement applies to drivers who are 70 years or older when renewing their California driver’s license?

They must take the knowledge test every renewal cycle

They must take a behind-the-wheel driving test

They may renew online without appearing in person

They must renew in person and pass a vision test

💡 Explanation: Drivers 70+ must appear in person and complete a vision exam. Other tests may be required depending on individual circumstances.

17 / 46

Which of the following lighting and reflector requirements must a bicycle have when ridden at night?

A front white light visible from 300 feet and a red rear reflector or light visible from 500 feet

Reflectors only on the pedals and wheels

A rear red light visible from 200 feet and no front light required

Only a front reflector if the rider wears bright clothing

💡 Explanation: At night, a bicycle must have a front white light visible from 300 feet, a rear red reflector or red light visible from 500 feet, white or yellow reflectors on each pedal, the rider’s shoes, or ankles visible from 200 feet, and a white or yellow reflector on the front wheel and a white or red reflector on the rear wheel, or reflectorized tires.

18 / 46

Why can side airbags be dangerous for children seated next to them?

They block the child’s view of the driver

They do not protect against side impacts

They can deploy with enough force to cause injury or death

They prevent the child from using a seat belt properly

💡 Explanation: Side airbags deploy with strong force during a collision, which can seriously injure or kill a child seated directly beside them. Children should ride properly restrained in the back seat whenever possible. If a child must ride in the front due to specific exceptions, the seat should be moved as far back as possible to maximize safety.

19 / 46

If you are under 18 and applying for a California driver’s license, when can you start using your instruction permit?

Only after a parent or guardian signs your application.

Once you turn 16 years old.

After you begin behind-the-wheel training with a licensed instructor who validates the permit.

As soon as you receive it from the DMV.

💡 Explanation: Drivers under 18 must start behind-the-wheel training with a licensed instructor before using their instruction permit. The instructor validates the permit, confirming that training has officially begun.

20 / 46

When a streetcar or trolley is stopped at a safety zone or traffic light, what is the maximum speed you may pass at?

10 mph

5 mph

15 mph

You are not allowed to pass at all

💡 Explanation: When a streetcar or trolley is stopped at a safety zone or traffic light, you may pass on the right side, outside the safety zone, at no more than 10 mph. Drive slowly and be ready to stop for pedestrians boarding or crossing.

21 / 46

What is the minimum safe distance you must maintain when passing a bicyclist on the road?

Two feet

One foot

Five feet

Three feet

💡 Explanation: California law requires drivers to leave at least three feet of space when passing a bicyclist. If there isn’t enough room to pass safely, slow down and wait until it’s safe to do so.

22 / 46

What do double solid yellow lines in the center of a roadway indicate?

You may cross them freely to change lanes

You must stay to the right of them and may only cross to turn left into or out of a driveway, private road, or to make a U-turn

They separate lanes of traffic moving in the same direction

You may cross them to pass slower traffic when it’s safe

💡 Explanation: Double solid yellow lines separate traffic moving in opposite directions and indicate that passing is not allowed. Drivers may cross these lines only to turn left into or out of a driveway, private road, or to make a legal U-turn, or when instructed by traffic control signs or road workers.

23 / 46

On a two-lane road, when is it safe to pass while approaching a hill or curve?

As soon as oncoming traffic appears far in the distance

When the center line is broken and no headlights are visible

Only if you can see at least one-third of a mile of clear roadway ahead

Whenever the vehicle ahead is 10 mph under the speed limit

24 / 46

What is the primary purpose of the passing lane on a multilane highway in California?

To use as a cruising lane during light traffic

To merge into traffic from on-ramps

To pass other vehicles safely, then return to a slower lane when finished

To drive at a slower, steady speed for fuel efficiency

💡 Explanation: The far-left lane (passing lane) is meant for overtaking slower vehicles. Once you’ve passed, return to the right lane to keep traffic flowing smoothly and avoid blocking faster drivers.

25 / 46

When the DMV conducts a medical or cognitive driver reexamination to evaluate whether someone can safely continue driving, which of the following is something the DMV cannot do?

Assign you to a mandatory private driving course

Require you to take a knowledge, vision, or driving test

Issue a limited-term driver’s license based on your condition

Request medical information from you or your physician

💡 Explanation: The DMV has wide authority during a reexamination, including requesting medical records, requiring testing, issuing a limited-term license, taking no action, or suspending/revoking driving privileges if there is an immediate safety threat. However, the DMV cannot assign or mandate training through a private driving school—this is not part of its administrative authority.

26 / 46

On icy roads, what is the safest maximum speed?

10 mph

Any speed if you have snow tires

15 mph

5 mph

💡 Explanation: Ice provides almost no traction. The DMV warns drivers not to exceed 5 mph on icy roads to avoid losing control of the vehicle.

27 / 46

Which of the following symptoms may indicate carbon monoxide exposure while driving?

Tiredness, ringing in the ears, or dizziness

Sudden hunger and dry mouth

Leg cramps and cold hands

Sharp chest pain and blurred vision

💡 Explanation: Carbon monoxide poisoning often causes tiredness, yawning, nausea, dizziness, headache, or ringing in the ears. Drivers who experience these signs should immediately ventilate the vehicle and have the exhaust system inspected.

28 / 46

What is the correct purpose of the center left turn lane on a two-way street?

To merge into faster traffic

To pass slower traffic before turning left

To prepare for or make a left turn or U-turn

To travel straight when traffic is heavy

💡 Explanation: The center left turn lane is designed only for preparing or completing a left turn or U-turn. It should never be used for passing or as a regular driving lane.

29 / 46

When using hand and arm signals, how should you signal a left turn if your turn signals are not working?

Extend your right arm straight out of the window

Extend your left arm upward

Extend your left arm downward

Extend your left arm straight out of the window

💡 Explanation: A left turn is signaled by extending your left arm straight out horizontally from the driver’s side window so others clearly see your intent to turn left.

You are driving on a one-way street. When is passing another vehicle on the right allowed?

If there is more than one lane in your direction and it can be done safely.

Only if traffic is moving slower than 25 mph.

Only if the vehicle ahead is signaling a right turn.

Never, you can only pass on the left.

💡 Explanation: On a one-way street with multiple lanes, you may pass on either side if conditions permit. Always check mirrors and blind spots, and ensure the lane change is legal and safe.

31 / 46

When driving within 500 feet of a school while children are outside or crossing, what is the maximum lawful speed unless otherwise posted?

30 mph

15 mph

20 mph

25 mph

💡 Explanation: In California, the speed limit near schools is 25 mph within 500 feet when children are present, unless a lower limit (such as 15 mph) is posted. Always reduce speed further if conditions make it unsafe.

32 / 46

When entering traffic from a full stop, what should you do before moving into a lane?

Accelerate quickly without signaling

Enter slowly and let other drivers adjust

Signal and wait for a gap large enough to reach the speed of traffic

Move into any available space, even if it’s small

💡 Explanation: Always signal and wait for a large enough space to merge smoothly. You must be able to accelerate up to traffic speed without forcing others to slow down suddenly.

If your car breaks down and you must stop on the road, what should you do first to stay safe?

Leave your vehicle in the lane and wait behind it

Step out immediately to flag traffic

Turn on your emergency flashers and, if possible, move your car off the roadway

Call for help without using any lights

💡 Explanation: In case of a vehicle breakdown, turn on your emergency flashers right away to warn others and pull off the road if it’s safe. Staying visible and out of traffic lanes greatly reduces your risk of being hit.

35 / 46

What does the three-second rule help a driver determine?

The amount of time before a yellow light changes to red

How closely you are following the vehicle ahead

How long it takes to stop at 55 mph

The minimum time needed to change lanes safely

💡 Explanation: The three-second rule helps drivers estimate a safe following distance. When the vehicle ahead passes a fixed point, you should reach the same point no sooner than three seconds later. If you arrive sooner, you are following too closely and may not have enough time to react.

36 / 46

What happens if you refuse to take a required chemical test (blood, breath, or urine) after a lawful DUI arrest in California?

You receive only a warning, with no license consequences

You may request to take the test at a later time instead

DMV will automatically suspend or revoke your driving privilege

The officer must release you because testing is optional

💡 Explanation: Under California’s implied consent law, refusing a required chemical test after a DUI arrest results in an automatic license suspension or revocation—regardless of the court outcome.

37 / 46

When will the FSP tow your vehicle free of charge?

After any collision, regardless of CHP direction

Only if your vehicle stops running and they cannot restart it

A California-licensed driver who is at least 25 years old

A parent or sibling age 18 or older

A driving school staff member by phone

💡 Explanation: The 50 required practice hours — including 10 at night — must be done with a California-licensed driver age 25 or older seated next to the permit holder.

39 / 46

When should you use your vehicle’s horn according to California driving rules?

To encourage a slow driver to move out of your lane

To hurry other drivers through intersections

To signal another driver to let you merge faster

To warn other drivers of a possible collision or when approaching a blind curve on a narrow mountain road

💡 Explanation: Use your horn only for safety reasons, such as avoiding a collision or alerting oncoming traffic on a narrow mountain road where visibility is limited to less than 200 feet. Misusing your horn can startle others and create unsafe conditions.

You may text if you are driving under 25 mph

You may hold the phone if you use speaker mode

When it’s dark enough that you can’t see from 1,000 feet away

All options are correct

During fog, rain, or snow

Beginning 30 minutes after sunset and until 30 minutes before sunrise

💡 Explanation: Use headlights after sunset and before sunrise, whenever visibility is poor (e.g., you can’t see 1,000 feet ahead), and during adverse weather like fog, rain, or snow so others can see you.

43 / 46

What is the correct action when you encounter a funeral procession on the road?

Drive through if you have a green light

Honk to alert them to speed up

Join the procession to move faster

Yield and allow the entire procession with headlights and markers to pass

💡 Explanation: Funeral processions are led by law enforcement and have the right-of-way. Cutting through or interrupting a procession is illegal and disrespectful; drivers must wait until it has completely passed.
