Sample sign questions
You approach an intersection and this sign faces you. What must you do?
- A Slow down and stop only if cross traffic is close
- B Stop only when a pedestrian is waiting at the corner
- C Get ready, because you will need to stop farther ahead
- D Come to a full stop, then go only when the way is clear
Show answer
D. Come to a full stop, then go only when the way is clear
The red octagon is used for one sign only, and it means a full stop is always required. After stopping, yield to cross traffic and pedestrians and go only when it is safe. Because no other sign shares this shape, you can recognize it even when you cannot read the word.

What does this sign require you to do?
- A Make a full stop every time before you enter
- B Slow down and let other traffic go first, stopping if needed
- C Keep your speed, because cross traffic must slow down and let you in
- D Watch for a traffic signal around the next bend
Show answer
B. Slow down and let other traffic go first, stopping if needed
The downward-pointing triangle is used only for the sign that tells you to yield. You must slow to a safe speed and stop if needed so you do not interfere with traffic or pedestrians who have the right-of-way. If the way is clear, you may continue without a full stop.

This red plaque is mounted directly below a red octagonal sign. What does it tell you?
- A Only traffic going straight through has to stop
- B Traffic on every approach to the intersection must stop
- C Cross traffic does not stop, so wait for a long gap
- D Drivers turning right may go without stopping
Show answer
B. Traffic on every approach to the intersection must stop
This plaque is added under the stop sign when all approaches to an intersection are stop-controlled. Knowing everyone must stop helps you take turns: generally the first vehicle to stop goes first. It does not change your duty to stop fully and look before you go.

This white sign is posted along a road. What does it tell you?
- A A suggested safe speed for a curve just ahead
- B The highest legal speed allowed on this section of road
- C The slowest speed you are allowed to drive here
- D A speed that applies only while the yellow lights above it are flashing
Show answer
B. The highest legal speed allowed on this section of road
White is the color of regulatory signs, which state the law. This one shows the maximum speed set by law or by the road agency, always a multiple of 5 mph. You must still drive slower than the limit when weather, traffic or visibility make that speed unsafe.

You see this sign facing you at the entrance to a road. What does it mean?
- A Traffic on this road flows one way, to your right
- B The road ahead is closed for construction work until further notice
- C You must not drive onto this road from where you are
- D Stop and wait for a gap before you turn onto it
Show answer
C. You must not drive onto this road from where you are
Red on a sign means stop or prohibition, and this red circle with a white bar forbids entry. It is placed where a driver could wrongly enter a one-way road, a divided highway or a freeway ramp. If you see it facing you, do not enter; find another route.
