Texas Driver's License Knowledge TestSafe Driving PracticesEasy

A driver is following another vehicle on a dry road. The vehicle ahead suddenly stops. To react safely, how many seconds of following distance should the driver maintain under normal conditions?

  1. A1 second
  2. B4 seconds
  3. C3 seconds
  4. D2 seconds
Show answer & explanation

Correct answer: C. 3 seconds

The Texas Driver Handbook recommends a minimum of a three-second following distance under ideal driving conditions. This provides enough time to react and stop safely if the vehicle ahead suddenly brakes.

Why the other options are wrong

  • A. 1 second is far too short and does not allow adequate reaction time.
  • B. 4 seconds is a good distance, especially in less than ideal conditions, but 3 seconds is the minimum for normal conditions.
  • D. 2 seconds is insufficient for most drivers to react and stop safely.

Three-Second Rule

The three-second rule is a guideline for maintaining a safe following distance. A driver should count three seconds from when the vehicle ahead passes a fixed object until their own vehicle passes the same object.

  • Minimum for ideal conditions.
  • Increases reaction time.
  • Provides stopping distance.

Memory trick: Three seconds to see, react, and be free!
