What does a flashing red traffic light mean?

Same as a STOP sign: stop, then go when it is safe.

  1. Slow down and keep going
  2. Stop and wait for green
  3. Stop, then go when safe ✔

Why: A flashing red light works just like a STOP sign. Come to a full stop, yield to anyone with the right-of-way, then go when it is clear.

Huh, didn't know that: A steady red light is different: stop and do not go until the light is green (or a legal right on red).

The dad joke
Why was the traffic light blushing? It saw the car changing.
