Show answer & explanationAnswer & explanation
Correct answer: C. Three seconds.
Florida law recommends a minimum following distance of three seconds under normal driving conditions. This provides enough time to react and stop safely.
Why the other options are wrong
- A. Four seconds is a good practice, especially in adverse conditions, but three seconds is the minimum for normal conditions.
- B. One car length is generally insufficient for safe stopping distance, especially at higher speeds.
- D. While better than one car length, two seconds is often insufficient, particularly in adverse conditions.
Three-Second Rule
The three-second rule is a guideline for maintaining a safe following distance by counting three seconds after the vehicle ahead passes a fixed object.
- Minimum safe following distance.
- Count three seconds after vehicle ahead passes a fixed point.
- Increase distance in adverse conditions (rain, fog, heavy traffic).
Memory trick: Three seconds gives you space to think and react.
