  1. AFour seconds.
  2. BOne car length.
  3. CThree seconds.
  4. DTwo seconds.
Show answer & 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.
