Rules of the Road - DRIVING INSTRUCTOR CA

Rules of the Road #1

Learn the core driving laws and essential rules you need for everyday safe driving.

1 / 20

What does a green arrow mean?

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

You must stop before making the turn.

Oncoming vehicles also have a green light.

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

💡 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.

2 / 20

What does a solid green light mean?

Go immediately without checking for pedestrians.

Proceed only if you are turning left.

Stop, then go when the intersection is clear.

Go, but only if the intersection is clear and it’s safe to proceed.

💡 Explanation: A green light means you may go if the way is clear, but you must yield to any vehicle, bicyclist, or pedestrian already in the intersection. Never enter an intersection unless there’s enough space to completely cross before the signal turns red.

3 / 20

You’re 18 years old and have a California instruction permit. Who must be with you while you practice driving?

A California-licensed driver who is at least 18, sitting beside you in the front seat.

No one — you can drive alone after sunset.

A friend your age who already has a license.

Any adult 18 or older sitting in the back seat.

💡 Explanation: At 18, you still need a California-licensed adult with you while you practice. They must sit close enough to take control of the car if needed.

4 / 20

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

Commercial Class A license

Temporary learner’s permit

Noncommercial Class C license

Motorcycle Class M license

💡 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.

5 / 20

You recently moved to a new apartment in California. How long do you have to notify the DMV of your new address?

15 days

Only when you renew your license

30 days

10 days

💡 Explanation: California law requires drivers to update their address with the DMV within 10 days of moving. You can do it online or by mail, and you’re responsible for keeping your mailing address current, even if you don’t request a new license card.

6 / 20

What does a red arrow signal mean?

Proceed with caution while turning.

Stop, and remain stopped until a green arrow or green light appears.

Stop, but you may turn right if it’s safe.

You can turn after yielding to all traffic and pedestrians.

💡 Explanation: A red arrow means you must stop and not turn in that direction until a green signal or green arrow appears. Turning during a red arrow is illegal and unsafe.

7 / 20

When approaching and driving through a roundabout, what should you do?

Use your horn or accelerate slightly to merge ahead of other vehicles

Stop in the roundabout to wait for a clear exit

Enter from the left if traffic seems lighter in that direction

Slow down, yield to traffic already in the roundabout, and enter to the right when safe

💡 Explanation: In a roundabout, traffic always moves counterclockwise. Drivers must enter to the right, yield to vehicles already circulating, and never stop inside the roundabout. Use your signal only when changing lanes or exiting, and if you miss your exit, simply continue around again safely.

8 / 20

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

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

Only when a police officer waves you through.

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.

💡 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.

9 / 20

When are you allowed to pass another vehicle on the right?

When the vehicle ahead is stopped at a red light.

When the vehicle ahead is turning left and you can safely pass on the right without leaving the roadway.

When the road has a solid yellow line.

Only when the other driver is driving below the speed limit.

💡 Explanation: In California, you may pass on the right only when it can be done safely and without driving off the paved or main-traveled part of the road — such as when the driver ahead is turning left or on a multi-lane highway.

10 / 20

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

Cross diagonally at any time if the road is clear.

Cross only straight across the street, not diagonally.

💡 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.

11 / 20

What does a flashing DON’T WALK or flashing raised hand signal mean for pedestrians?

Do not start crossing; the signal is about to change.

Stop immediately in the middle of the street.

Continue crossing only if no vehicles are present.

Begin crossing quickly before the light changes.

💡 Explanation: A flashing DON’T WALK or raised hand means the pedestrian signal is about to change. You should not begin crossing, but drivers must still yield to pedestrians already in the crosswalk until they finish crossing safely.

12 / 20

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

Enter slowly and let other drivers adjust

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

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

Accelerate quickly without signaling

💡 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.

13 / 20

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

30 mph

15 mph

25 mph

20 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 / 20

You’re 15½ and applying for a California driver’s license. When can you schedule your behind-the-wheel driving test?

Immediately after getting your instruction permit

After holding a permit for at least 6 months or turning 18

As soon as you complete 10 hours of driving

Only after your parent signs a permission form

💡 Explanation: California requires teens to hold their instruction permit for a minimum of six months before they can take the behind-the-wheel test, unless they’ve already turned 18.

15 / 20

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

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

To merge into faster traffic

💡 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.

16 / 20

What is the legal BAC limit for drivers aged 21 or older in California?

0.01%

0.08%

0.05%

0.04%

💡 Explanation: In California, it is illegal for a person 21 or older to operate a vehicle with a BAC of 0.08% or higher. This is the standard per-se DUI threshold for adult drivers.

17 / 20

What is the maximum speed limit on most California highways unless otherwise posted?

55 mph

70 mph

60 mph

65 mph

💡 Explanation: The maximum speed limit on most California highways is 65 mph unless signs indicate a different limit. On two-lane undivided highways and for vehicles towing trailers, the limit is 55 mph.

18 / 20

What does a yellow arrow indicate?

You must stop immediately.

You may turn in any direction with caution.

The next signal will always be green.

The protected turn is ending; prepare to stop if it’s safe.

💡 Explanation: A yellow arrow means your protected turning time is ending. The signal will soon change — it may turn to a green or red traffic light, or to a red arrow. If you can stop safely, do so. If you are already in the intersection, complete your turn with caution and be ready for the next signal.

19 / 20

What should you do when you see an emergency vehicle approaching with sirens and red lights activated?

Pull to the left side of the road to make space

Speed up to stay ahead of the emergency vehicle

Stop immediately in your lane, even if in the middle of an intersection

Drive to the right edge of the road and stop until the emergency vehicle passes

💡 Explanation: When an emergency vehicle with red lights and siren approaches, you must move to the right edge of the road and stop until it passes. Never stop in an intersection — clear it first, then pull over. This ensures the emergency vehicle can pass quickly and safely.

20 / 20

What should you do when entering traffic from a driveway, side road, or parking space?

Enter quickly to match the flow of traffic

Stop only if you see large vehicles approaching

Proceed with caution and yield to vehicles already in the lane

Turn on hazard lights before entering

💡 Explanation: When entering from a driveway or side road, you must yield to traffic already on the roadway and wait for a safe gap. Signal, check mirrors and blind spots (and the sidewalk for pedestrians and bicyclists), then accelerate smoothly to match the flow without forcing other drivers to brake.

Rules of the Road #2

Strengthen your understanding of lane use, speed limits, right-of-way, and safe decision-making.

1 / 20

During your behind-the-wheel driving test, you realize your vehicle’s dash camera is recording. What must you do before the test begins?

Leave it on if it only records video, not sound

Ask the examiner for permission to keep it running

Keep it on as long as you do not watch the screen while driving

Turn it off or completely block it so it cannot record during the test

💡 Explanation: The DMV prohibits any recording device—video or audio—during the driving test. If it cannot be powered off, it must be fully covered or blocked to ensure no part of the test is recorded.

2 / 20

Where is passing prohibited under California law?

Within 100 feet of a railroad crossing

All options are correct

Within 100 feet of an intersection

Within 100 feet of a bridge or tunnel

💡 Explanation: Passing is never allowed within 100 feet of an intersection, railroad crossing, bridge, or tunnel. These areas are considered high-risk zones where another vehicle or obstacle could appear unexpectedly.

3 / 20

You’re 17 and taking the California DMV knowledge test for the first time. If you don’t pass, when can you try again?

The next day

After 7 days, not counting the day you failed

Immediately, if you make an appointment

After 14 days, including weekends

💡 Explanation: Minors who fail the DMV written (knowledge) test must wait seven full days before retaking it. The waiting period doesn’t include the day of the failed attempt, giving time to review and study before trying again.

4 / 20

When should you use the right lane on a multi-lane road?

When entering or exiting traffic, or driving at a slower speed

When preparing to make a U-turn

When driving faster than surrounding traffic

When passing other vehicles or turning left

💡 Explanation: The right lane is used for entering or leaving traffic and for slower-moving vehicles. The left lane is reserved for passing and faster travel. Staying in your lane and avoiding frequent weaving improves safety and traffic flow.

5 / 20

If you are 17 and have a provisional license, who may ride with you when driving?

Any family members regardless of age

Only passengers over 21 years old

No one under 20, unless a California-licensed driver age 25 or older is in the car

Friends under 18 if everyone wears a seat belt

💡 Explanation: During the first year, a provisional driver cannot transport passengers under 20 unless accompanied by a California-licensed driver who is at least 25 or a parent/guardian.

6 / 20

When preparing to exit a California highway, when should you begin signaling?

About 100 feet before the exit

Only after you enter the exit lane

About 200 feet before the exit

About five seconds (around 400 feet) before the exit

💡 Explanation: Signal at least five seconds (approximately 400 feet) before your exit so drivers behind you have enough time to react and adjust safely.

7 / 20

When driving in California, how far in advance should you signal before making a turn?

At least 100 feet before the turn

Only when other cars are nearby

At least 50 feet before the turn

At least 25 feet before the turn

💡 Explanation: You must signal at least 100 feet before turning so other drivers and pedestrians have time to react. Signaling early helps prevent confusion and reduces the chance of collisions.

8 / 20

What documents must a driver provide when stopped by law enforcement in California?

Driver’s license, proof of insurance, and vehicle registration.

Only proof of insurance.

Driver’s license and proof of address.

Only a driver’s license.

💡 Explanation: California law requires drivers to show their driver’s license, proof of insurance, and vehicle registration when requested by a law enforcement officer during a stop. Failure to present them may lead to a citation or a limited vehicle search to locate the documents.

9 / 20

What does a flashing yellow arrow indicate?

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

Stop completely before turning left.

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

You may not turn until the light turns green.

💡 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.

10 / 20

When merging onto a California highway, which of the following actions is correct?

Stop at the end of the on-ramp until traffic clears

Match the speed of highway traffic and merge safely without crossing solid lines

Enter the highway at a slower speed to let others adjust

Cross multiple lanes at once to reach the far-left lane quickly

💡 Explanation: When merging onto a highway, you must adjust your speed to match the flow of traffic and merge only when it’s safe. Avoid stopping on the ramp unless absolutely necessary, and never cross solid lines. Merge one lane at a time while checking mirrors and blind spots.

11 / 20

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

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

Speed up to give them more space.

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

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.

12 / 20

How far are you legally allowed to drive in a center left turn lane before making your turn?

No more than 300 feet

No more than 200 feet

Until the next intersection

No more than 100 feet

💡 Explanation: You may drive in the center left turn lane for up to 200 feet while positioning your vehicle for a left turn or U-turn. This limit prevents drivers from using the lane as a regular travel or passing lane.

13 / 20

At a green light, when should you avoid entering the intersection?

When the intersection is clear, though the next signal one block ahead is red and traffic is moving slowly

When the light has just turned green but there’s open space past the crosswalk for your car

When traffic beyond the intersection is stopped and there isn’t enough room for your vehicle on the far side

When the light is green, you must move forward under any condition

💡 Explanation: A green light does not give you permission to block an intersection. You must wait until you can clear it completely. Entering when vehicles ahead are stopped can cause gridlock and is a violation under California traffic law.

14 / 20

A 16-year-old with a California permit must log 50 hours of practice driving before testing for a license. Who must supervise these hours?

Any adult with at least five years of driving experience

A driving school staff member by phone

A parent or sibling age 18 or older

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

💡 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.

15 / 20

If there are no pedestrian signals at an intersection, what should pedestrians do?

Cross only when there are no vehicles in sight.

Obey the same traffic signal lights as drivers.

Cross quickly without waiting for the light.

Use hand signals to indicate crossing.

💡 Explanation: When there are no pedestrian signals, pedestrians must follow the same traffic lights controlling vehicle movement. For example, cross on green and never enter the crosswalk during a red light.

16 / 20

When is it legal to drive using only your parking lights in California?

When it’s just starting to get dark outside

Between sunrise and sunset on clear days

Never — it’s against the law to drive with only parking lights

When driving through a well-lit area at night

💡 Explanation: Parking lights are not meant for driving at any time. California law prohibits using only parking lights while moving, whether it’s day or night — they are for stationary vehicles only.

17 / 20

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

Never, you can only pass on the left.

Only if traffic is moving slower than 25 mph.

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

Only if the vehicle ahead is signaling a right turn.

💡 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.

18 / 20

A 17-year-old has a provisional California driver’s license, but their parent decides the teen isn’t ready to drive yet. What can the parent legally do?

Contact the DMV and verbally request suspension of the license

File a police report to revoke the license

Keep the teen’s license card at home to stop them from driving

Submit a “Request for Cancellation or Surrender of a Driver License or ID Card” form to the DMV

💡 Explanation: California law allows a parent or legal guardian to cancel their minor child’s license by submitting an official Request for Cancellation or Surrender form to the DMV. This formally ends the teen’s driving privilege.

19 / 20

What should you do when approaching a solid yellow traffic light?

Always stop, even if you are already in the intersection.

Ignore it if there are no other vehicles nearby.

Speed up to clear the intersection before it turns red.

Stop, if you can do so safely. If you can’t stop safely, proceed with caution.

💡 Explanation: A solid yellow light warns that the signal is about to turn red. Stop if it’s safe to do so. If you’re too close to the intersection to stop safely, cross carefully.

20 / 20

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

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

To drive at a slower, steady speed for fuel efficiency

To use as a cruising lane during light traffic

To merge into traffic from on-ramps

💡 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.
