What does a flashing yellow traffic signal light direct a driver to do?

  1. Stop and proceed when the traffic allows you to proceed safely.
  2. Slow down and proceed with caution. ✓
  3. Stop and wait for a flashing green signal.

Answer: B. Slow down and proceed with caution.

Slow down and proceed with caution when a traffic signal light is flashing yellow.

Why this is the answer

The handbook says a flashing yellow light is a warning to proceed carefully, slow down, and stay alert. It also says plainly that you do not need to stop. That matches the choice to slow down and continue cautiously. The flashing yellow signal is not telling you to come to a full stop first, so treating it like a stop signal would be wrong.

Why the other answers are wrong

Remember it

Think yellow flash, ease off the gas: slow down and look, with no full stop required.
