The light turns yellow as you approach an intersection. What does Kentucky law say?
- A Stop if you can do so safely
- B Speed up to clear the intersection before red
- C You may enter as long as the light is not red yet when you leave
- D Stop immediately, even if it means braking hard
Show answer
A. Stop if you can do so safely
A yellow light means the signal is about to turn red, so stop if you can do it safely. A vehicle that entered on yellow may clear the intersection, but it is illegal to enter after the light turns red.

When may you turn LEFT on a red light in Kentucky?

- B Never; left turns on red are always illegal
- C Only from a one-way street onto a one-way street
- D From any street, if no oncoming traffic is visible

Kentucky allows a left turn on red only from a one-way street onto another one-way street. You must stop first and then turn when the roadway is clear of vehicles and pedestrians.

What does a flashing red traffic light mean?
- A Slow down and proceed with caution without stopping
- B Come to a full stop and go only when it is clear
- C Stop only if cross traffic is present
- D The signal is broken, so treat the intersection as uncontrolled
Show answer
B. Come to a full stop and go only when it is clear
Treat a flashing red light like a stop sign: come to a full stop and go only when the way is clear. A flashing yellow, by contrast, means slow down and watch for others.
