- ATwo seconds
- BOne car length
- CFour seconds
- DThree seconds
Show answer & explanationAnswer & explanation
Correct answer: D. Three seconds
The Florida Driver's Handbook recommends a minimum three-second following distance under normal driving conditions. This provides enough time to react and stop safely.
Why the other options are wrong
- A. Two seconds is often cited as a bare minimum but is generally not considered sufficient for safety under normal conditions.
- B. Car lengths are unreliable as a measure because vehicle lengths vary greatly.
- C. Four seconds is a good distance, especially in adverse conditions, but three seconds is the minimum for normal conditions.
Safe Following Distance (3-Second Rule)
Under normal driving conditions, maintain at least a three-second following distance behind the vehicle in front of you to allow for adequate reaction and stopping time.
- Measured by picking a fixed object and counting 'one thousand one, one thousand two, one thousand three'.
- Increases in adverse weather (rain, fog) or heavy vehicles.
- Provides a buffer for emergencies.
Memory trick: Three-Second buffer adds safety to your drive.
