When a drawbridge signal is red, you should:
- Come to a complete stop. ✓
- Quickly speed up.
- Proceed with caution.
- Stop only if you see a boat.
Answer: A. Come to a complete stop.
When the drawbridge signal is red, come to a complete stop at the marked stop line.
Why this is the answer
The handbook's drawbridge signal section says a red light means you stop completely at the marked stop line. It explains the bridge is in operation and the roadway is closed to all pedestrian and motor vehicle traffic, so there is nothing to proceed through until the signal changes. That is why stopping fully, rather than slowing or rolling ahead, is the correct response to the red drawbridge light.
Why the other answers are wrong
- B. Quickly speed up. — Speeding up is the opposite of what the red signal calls for, since the roadway is closed while the bridge operates.
- C. Proceed with caution. — Proceeding with caution describes the green drawbridge signal, not the red one.
- D. Stop only if you see a boat. — The red signal stops you because the bridge is in operation and the roadway is closed, not because you happen to spot a boat.
Remember it
On a drawbridge, red means the road is shut for the bridge, so treat it like any red light and stop at the line.
