Correct answer: Proceed with caution; you do not need to stop
This flashing signal is telling you to slow down and stay alert as you continue through; unlike a flashing red light, a full stop is not required.

2. A broken white line between two lanes of traffic means:
Correct answer: Lanes go the same way; you may change lanes when safe
A broken white line separates lanes going in the same direction. You may change lanes across it when it is safe.
3. A flashing red traffic signal means you should:
Correct answer: Stop, then go when it is safe
A flashing red light means the same as a stop sign: come to a complete stop, then proceed when it is safe.
4. A steady green arrow pointing left at a traffic signal means:
Correct answer: You may turn in the arrow's direction; oncoming traffic is stopped
A green left arrow is a protected turn: you may turn in the arrow's direction because oncoming traffic is being held by a red light. Still watch for pedestrians and finish the turn before the arrow ends.
5. A flashing yellow left-turn arrow tells you that you may:
Correct answer: Turn left after yielding to oncoming traffic
A flashing yellow arrow means the left turn is not protected. You may turn only after yielding to oncoming traffic and proceeding with caution.

6. Double solid white lines separating a regular lane from a carpool (HOV) lane mean you should:
Correct answer: Never cross them; wait for a broken white line section
Crossing that double white barrier is not permitted; hold your lane until the marking becomes a single broken line, which signals a legal spot to merge into or out of the carpool lane.

7. A row of solid white triangles painted across a lane, pointing toward approaching traffic, is called a:
Correct answer: Yield line
This is a yield line. It marks the point where an approaching vehicle must yield or stop, with the triangles pointing toward the traffic that must yield.

8. You approach an intersection where the traffic signals are completely dark and not working. You should:
Correct answer: Treat it as an all-way (four-way) stop
When signal lights are dark or not functioning, treat the intersection as an all-way (four-way) stop. Stop, then proceed in turn using the normal right-of-way rules.
9. A center lane bordered by a solid yellow line on the outside and a broken yellow line on the inside is meant to be used for:
Correct answer: Left turns, shared by traffic from both directions
This is a two-way left-turn lane. Drivers from both directions may enter it only to prepare for and make a left turn; it is never used for passing or through travel.

10. A broken (dashed) yellow center line means:
Correct answer: You may pass when it is safe
A broken yellow line means you may pass or cross it when it is safe to do so. The two-way road carries traffic in opposite directions.
11. A steady yellow traffic light means:
Correct answer: The light is about to turn red; stop if you safely can
A steady yellow light warns that the signal is about to turn red. Stop if you can do so safely; do not try to 'beat' the light.
12. Two solid yellow lines painted down the center of a road mean:
Correct answer: Do not pass; cross only to turn left
Double solid yellow lines mean neither direction may pass. You may cross them only to turn left into or out of a driveway or private road.
