What should you do at an intersection with a flashing yellow signal light?
- Maintain your speed but watch for other vehicles.
- Stop before crossing the intersection.
- Slow down and cross the intersection carefully. ✓
Answer: C. Slow down and cross the intersection carefully.
At a flashing yellow signal light you should slow down and cross the intersection carefully.
Why this is the answer
The handbook describes a flashing yellow light as a warning to proceed with caution: slow down and stay alert. It also says plainly that you do not need to stop. That matches slowing down and crossing carefully, and it rules out both holding your current speed without easing off and making a full stop where none is required.
Why the other answers are wrong
- A. Maintain your speed but watch for other vehicles. — Keeping your speed the same ignores the handbook's instruction to slow down at a flashing yellow light, which is a warning to proceed with caution.
- B. Stop before crossing the intersection. — A full stop belongs to a flashing red light or a solid red light, since the handbook says a flashing yellow means you do not need to stop.
Remember it
Flashing yellow is a warning, not a command to stop: ease off the gas, stay sharp, and roll through when it is clear.
