Which of the following lights indicates that you should slow down and proceed with caution at an intersection?
- A flashing yellow light ✓
- A flashing red light
- A solid yellow light
- A solid red light
Answer: A. A flashing yellow light
A flashing yellow light is the signal that tells you to slow down and go through the intersection with caution.
Why this is the answer
The Texas handbook describes a flashing yellow light as a warning to drivers to slow down and proceed with caution. That matches the question exactly. The same chapter describes a steady yellow light differently: it warns that the light is about to turn red, and you must stop before the crosswalk if you can do so safely. So the flashing yellow signal is the one tied to slowing down and using caution rather than preparing to stop.
Why the other answers are wrong
- B. A flashing red light — A flashing red light is not the caution signal described here; the handbook passage covers the flashing yellow light for slowing down and proceeding with caution.
- C. A solid yellow light — A steady yellow light warns that the signal is about to change to red and tells you to stop before the crosswalk if you can do so safely, so it is not the slow-down-and-proceed signal.
- D. A solid red light — A steady red light is a stop signal, not a caution signal for moving through the intersection.
Remember it
Flashing means treat it as a warning sign, not a stop light: ease off the gas and look both ways.
