1 / 20
You approach a roadway sign shaped like a horizontal rectangle (wider than tall) with black letters on a white background reading “ONE WAY” and an arrow pointing right. How should you interpret this sign?
💡 Explanation: A white regulatory rectangular sign with “ONE WAY” and an arrow means the road is legally one-direction only. Driving in the opposite direction is illegal and extremely hazardous.
2 / 20
What does this sign indicate?
💡 Explanation: A Slippery When Wet sign warns you that the road surface can become slick when it rains or when moisture is present. Reduce your speed, avoid sudden braking or sharp turns, and keep extra space between you and the vehicle ahead. Smooth steering and gentle braking help prevent skids, especially on curves or older pavement.

What does a broken white line on the roadway indicate?
💡 Explanation: A broken white line defines lanes moving in the same direction. You may change lanes across it only when it’s safe and legal to do so.
4 / 20
A rectangular white sign with black or red lettering is what type of sign?
💡 Explanation: White rectangular signs communicate laws and regulations that drivers must follow, such as speed limits, lane use, parking restrictions, or “Do Not Enter” instructions.
5 / 20
What do double solid white lines on the road indicate?
💡 Explanation: Double solid white lines create a lane barrier—commonly between a carpool (HOV) lane and regular traffic or near freeway ramps. Lane changes are prohibited until the lines become broken white.
6 / 20
💡 Explanation: A Two Way Traffic Ahead sign alerts you that the road ahead will no longer be separated—you’ll be sharing the roadway with oncoming vehicles. When this appears, stay centered in your lane, avoid passing unless it’s clearly safe and legal, and be prepared for opposing traffic to be much closer than on a divided highway.
7 / 20
💡 Explanation: The Merging Traffic sign tells you that vehicles from a lane on the right will enter your lane. When you see this sign, watch your mirrors, check your blind spots, and be ready to adjust your speed so merging drivers can join safely. Creating a smooth gap early helps prevent sudden braking or last-second lane changes.
8 / 20
What do double solid yellow lines in the center of a roadway indicate?
💡 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.
9 / 20
💡 Explanation: An Added Lane sign means another lane will join the roadway without merging. Drivers in the new lane do not need to merge into your lane, and you do not need to move over. Still, stay aware of vehicles entering the roadway and maintain a steady speed so everyone transitions smoothly into their lanes.
10 / 20
You see a white square sign with a red circle and slash over the image of a U-turn. What must you do?
💡 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.
11 / 20
What type of sign is a diamond-shaped traffic sign?
💡 Explanation: Diamond-shaped signs are used for warnings. They alert drivers to possible hazards or changing road conditions ahead, such as curves, merging traffic, or pedestrian crossings.
12 / 20
💡 Explanation: A Railroad Crossing Ahead sign warns you that train tracks are coming up, and you must be prepared to slow down and look for trains. Trains move faster than they appear and cannot stop quickly, so approach the tracks with caution. Scan both directions, be ready to stop if signals activate, and never stop on the tracks or try to beat a train through the crossing.
13 / 20
When are you allowed to pass another vehicle on a two-way road with a broken yellow line?
💡 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.
14 / 20
You see a lane marked with large broken white lines ahead on the freeway. What does this indicate?
💡 Explanation: Large broken white lines mark the end of a lane, often approaching an exit or merge area. Be ready to exit or merge safely, following any posted signs.
15 / 20
What does a five-sided (pentagon-shaped) traffic sign indicate?
💡 Explanation: The pentagon-shaped sign warns drivers they are near a school zone or a school crossing. Slow down, watch for children, and stop for pedestrians in the crosswalk.
16 / 20
💡 Explanation: A Lane Ends Ahead sign warns you that the lane on the right will end soon, and drivers in that lane must merge safely into the lane on the left. When you see this sign, check your mirrors, signal early, and find a safe gap to merge into. Drivers in the through-lane should be prepared for vehicles merging and avoid blocking or speeding up to prevent safe entry.
17 / 20
How are the pavement markings designed for a center left turn lane that separates traffic in both directions?
💡 Explanation: A center left turn lane is located in the middle of a two-way road and is marked by two sets of yellow lines — one solid and one broken on each side. This design shows that vehicles from either direction may enter the lane briefly to prepare for a left turn or U-turn, but not for passing or regular travel.
18 / 20
What does a single solid yellow line on your side of the road indicate?
💡 Explanation: A single solid yellow line marks the center of a two-way road. You must not pass when the solid yellow line is on your side, because it separates opposing traffic and passing would put you in the oncoming lane.
19 / 20
What does a single solid white line on the road indicate?
💡 Explanation: A single solid white line separates lanes traveling in the same direction, including on one-way streets. Drivers should not cross this line except when absolutely necessary and safe, such as avoiding a hazard.
20 / 20
You are driving a personal passenger vehicle and see a yellow circular sign with a large black “X” and the letters “R R” ahead. What should you do?
💡 Explanation: The circular yellow “R R” sign warns that a railroad crossing is ahead. When driving a personal passenger vehicle, you must slow down, look, and listen for trains, stopping only if one is approaching or the crossing is blocked.However, school buses, commercial passenger vehicles, and vehicles carrying hazardous materials must stop at all railroad crossings, even when no train is visible.
