You are coming to an intersection with a flashing red light. You should:

  1. Slow down and yield the right-of-way.
  2. Slow down and drive carefully through the intersection.
  3. Come to a complete stop, check the traffic, and go when it is safe to do so. ✓

Answer: C. Come to a complete stop, check the traffic, and go when it is safe to do so.

You should come to a complete stop, check the traffic, and go when it is safe to do so.

Why this is the answer

The handbook says a flashing red signal light means STOP. After you stop, you may go when it is safe. That is why the correct choice includes a complete stop before you check traffic and proceed. A flashing yellow light is the signal that tells you to slow down and proceed with caution without stopping, so slowing alone is not enough at a flashing red.

Why the other answers are wrong

Remember it

Red means stop, flashing or solid; flashing red lets you go only after you stop and check.
