A red flashing traffic light has the same meaning as a:

  1. Solid red light.
  2. Stop sign. ✓
  3. Yield sign.
  4. Caution sign.

Answer: B. Stop sign.

A red flashing traffic light means the same as a stop sign: stop, yield the right-of-way, and go only when it is safe.

Why this is the answer

The handbook's traffic-signal section says a flashing red signal carries the same instruction as a STOP sign. That means you bring the car to a halt, give the right-of-way, and continue only after you have checked that it is safe. The same passage treats steady red and flashing red as separate signals, so flashing red is not just another way of showing a solid red. The listed match is the stop sign.

Why the other answers are wrong

Remember it

Red flash, stop-sign task: halt, yield, then go when clear.
