When you arrive at an intersection with a flashing red light, you must
  1. stop as you would at a stop sign ✓
  2. slow down and yield the right of way
  3. slow down and proceed with caution
  4. wait until the light turns green

Answer: A. stop as you would at a stop sign

At a flashing red light, you must stop as you would at a stop sign: come to a complete stop, then continue only when it is safe.

Why this is the answer

The handbook says a flashing red light means you must stop, and then continue only when it is safe. It also describes flashing red as requiring a complete stop before you move into the intersection when it is clear. That matches the basic action of stopping at a stop sign: you bring the vehicle to a full stop first, then go when the way is safe. The rule is not to slow down and roll through, and it is not to wait for a green light.

Why the other answers are wrong

Remember it

Red flash: brake to a full stop, then go only when clear.
