Sample traffic signals questions
You reach an intersection where the traffic light is completely dark because of a power failure. What does Louisiana law say to do?
- A Yield only to vehicles on your left
- B Treat it as an all-way (four-way) stop
- C Follow the main road and do not stop
- D Go through if no cars are coming
Show answer
B. Treat it as an all-way (four-way) stop
When a traffic signal is not working, the intersection reverts to an all-way or four-way stop. Stop completely, then take turns, with the driver on the left yielding to the driver on the right if you arrive together.
The light turns yellow just after your front wheels have entered the intersection. What should you do?
- A Speed up to beat the red light
- B Stop at once, even though you are in the intersection
- C Back up behind the stop line
- D Continue safely through the intersection
Show answer
D. Continue safely through the intersection
A steady yellow light warns that the signal is about to turn red. Stop if you can do so before the stop bar, but if you are already in the intersection, continue safely through it.
What must you do at a flashing red traffic light?
- A Slow down and proceed with caution
- B Stop only if cross traffic is present
- C Wait until the light turns green
- D Stop completely, then go when it is safe, as at a stop sign
Show answer
D. Stop completely, then go when it is safe, as at a stop sign
A flashing red light means stop behind the stop bar, crosswalk or intersection and treat it like a stop sign. Come to a complete stop, look both ways and yield before entering.
In Louisiana, when may you turn LEFT on a steady red light?
- A From any street when no oncoming traffic is in sight
- B Never; left turns on red are always illegal
- C From a one-way street onto another one-way street, after stopping and yielding
- D Only when a green arrow is shown for the other direction
Show answer
C. From a one-way street onto another one-way street, after stopping and yielding
Some left turns on red are permitted when moving from a one-way street onto another one-way street. You must first stop and then yield to all traffic and pedestrians, and only where the turn is not prohibited.
