A flashing red traffic light at an intersection means:
- Slow down before entering.
- Stop before entering. ✓
- Stop and wait for the green light.
Answer: B. Stop before entering.
A flashing red traffic light means stop before entering the intersection.
Why this is the answer
The California Driver Handbook says a flashing red signal light means STOP. It also says that after stopping, you may go when it is safe. That makes a flashing red different from a flashing yellow, which only warns you to slow down and be alert. It also differs from a steady red arrow, where the handbook says to remain stopped until a green light or green arrow appears. For a flashing red, the required action is a stop before entering, then proceed only when safe.
Why the other answers are wrong
- A. Slow down before entering. — Slowing down before entering is not enough because a flashing red signal requires a stop, not just caution.
- C. Stop and wait for the green light. — Waiting for a green light is wrong because after stopping at a flashing red, you may go when it is safe.
Remember it
Treat a flashing red like a stop sign: come to a full stop, then go only when it is safe.
