When approaching a flashing yellow light, drivers should:

  1. Increase their speed.
  2. Come to a complete stop.
  3. Turn on their headlights.
  4. Slow down and proceed with caution. ✓

Answer: D. Slow down and proceed with caution.

When you approach a flashing yellow light, slow down and proceed with caution.

Why this is the answer

The Texas Driver Handbook covers this signal directly: a flashing yellow light warns drivers to slow down and go ahead carefully. It is not a stop signal the way a steady red light is, and it does not mean speed up. The handbook also contrasts it with the steady yellow light, which tells you to stop before the crosswalk if you can do so safely. With a flashing yellow, the message is simply to reduce speed and stay watchful as you continue.

Why the other answers are wrong

Remember it

Flashing yellow means ease off the gas and keep rolling; flashing red is the one that makes you stop.
