A yellow light that flashes on and off means:
- Stop and look for other vehicles, then go if there is no traffic.
- Stop and wait for a green light.
- Speed up to clear the intersection quickly.
- Slow down and proceed with caution. ✓
Answer: D. Slow down and proceed with caution.
A flashing yellow light means you slow down and go ahead with caution.
Why this is the answer
The Texas handbook treats a flashing yellow signal as a warning to reduce speed and continue carefully. It does not tell you to stop the way a steady yellow does when a safe stop is possible. The handbook's exact wording for the flashing yellow is to slow down and proceed with caution, so the choice that matches is the one about easing off the gas and moving through carefully rather than stopping or hurrying.
Why the other answers are wrong
- A. Stop and look for other vehicles, then go if there is no traffic. — A flashing yellow does not call for a complete stop first; the handbook links that stop-then-go pattern to a steady yellow when you can stop safely, not to the flashing signal.
- B. Stop and wait for a green light. — Waiting for a green light describes how you treat a red signal, while a flashing yellow lets you keep moving once you have slowed.
- C. Speed up to clear the intersection quickly. — Speeding up is the opposite of what the handbook says, since a flashing yellow warns you to slow down.
Remember it
Flashing yellow is a warning, not an order to halt: ease off the gas and roll through carefully.
