Sample traffic signals questions
A traffic light at an intersection has lost power and is dark. How should you treat it?

Show answer
D. As a stop sign
If a signal loses power or is not working right, proceed as if it were a stop sign. If an officer is directing traffic, follow the officer's directions instead.

You want to turn right on a steady red light and no sign prohibits it. What is the correct sequence?
- A Wait for the green light, since a steady red means no turning
- B Stop, then turn into the farthest open lane
- C Slow down, check left, then turn without stopping
- D Stop, yield to all traffic, then turn staying in your lane
Show answer
D. Stop, yield to all traffic, then turn staying in your lane
Wisconsin allows right turns on red after a full stop unless a sign prohibits it. Yield to all traffic and pedestrians, and stay in your lane through the turn.
The light turns steady yellow after you have already entered the intersection. What should you do?
- A Continue through the intersection
- B Speed up to beat the red light
- C Stop where you are in the intersection
- D Back up behind the stop line
Show answer
A. Continue through the intersection
A steady yellow means the light is about to turn red, so stop before the intersection if you can. If you are already in the intersection, do not stop; continue through.
