Sample questions from this test
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.

What does this work zone sign tell you?
- A The left lane of a multi-lane road is closed for work ahead
- B Traffic from both directions will share a single lane
- C The road becomes one-way for the work zone
- D A narrow bridge is ahead in the work zone
Show answer
B. Traffic from both directions will share a single lane
ONE LANE ROAD means both directions must take turns using one lane. Expect a flagger, a temporary signal or a pilot car to control who goes. Wait your turn and never follow the car ahead through without a signal to go.

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.

Near a railroad crossing you see a white sign that says DO NOT STOP ON TRACKS. Traffic ahead is backed up past the crossing. What should you do?
- A Wait before the crossing until there is room for your vehicle beyond the tracks
- B Drive onto the tracks and wait there only if no train is in sight
- C Stop on the tracks but leave room to back up if a train comes
- D Sound your horn so the traffic ahead moves forward
Show answer
A. Wait before the crossing until there is room for your vehicle beyond the tracks
This sign is posted where a line of traffic, such as one waiting at a nearby STOP sign or signal, could back up onto the tracks. Never stop on the tracks. Wait before the crossing until there is room for your whole vehicle on the other side.

In a work zone, a flagger holds up a paddle with an eight-sided red face. What must you do?
- A Slow down and keep moving through with extra care
- B Pull onto the shoulder and wait
- C Follow the pilot car through the zone
- D Stop, just as you would for a STOP sign
Show answer
D. Stop, just as you would for a STOP sign
A flagger's STOP/SLOW paddle uses the same octagon shape as a STOP sign, so its STOP face means stop. When the flagger turns it to SLOW, proceed carefully through the work zone.
