You must stop at an intersection when you see a:

  1. Flashing red light. ✓
  2. Steady yellow light.
  3. Yellow arrow.
  4. Flashing yellow light.

Answer: A. Flashing red light.

You must stop at the intersection when you see a flashing red light.

Why this is the answer

The Florida handbook lists a flashing red light under traffic signals and says to treat it like a stop sign: stop, then go ahead when it is safe. Because the light is red and flashing, the required first action is to stop at the intersection; you do not simply slow down or continue without stopping. The same passage treats flashing yellow as a caution signal, not a stop command, so the flashing red light is the one that matches the question.

Why the other answers are wrong

Remember it

A red flash acts like a stop sign: stop first, then move when the way is clear.
