If your turn signals fail, you should use ____ to indicate that you are turning.
- Your horn
- Your headlights
- Hand signals ✓
- Your emergency flashers
Answer: C. Hand signals
If your turn signals fail, use hand signals to show other drivers that you are turning.
Why this is the answer
The Florida handbook says you must use vehicle directional signals or hand signals to show others that you are turning. That means the hand signal is the listed backup when the vehicle's directional signals are not working. It is not enough to hope other drivers guess your intention; you still need to communicate the turn. The passage ties this directly to showing other drivers that you are turning, so hand signals are the correct choice.
Why the other answers are wrong
- A. Your horn — The handbook passage lists directional signals or hand signals for turns, not the horn, so the horn is not the stated substitute.
- B. Your headlights — Headlights are not named in the passage as a way to indicate a turn when signals fail.
- D. Your emergency flashers — Emergency flashers are not listed in the passage as the signal to use for a turn.
Remember it
If the lights quit, let your arm do the talking: use hand signals.
