How do you measure a three-second following distance?

  2. Count from when the car ahead passes a fixed object
  3. Measure it by the length of your car
  4. Look at the brake lights of the car ahead
Show answer

Correct answer: Count from when the car ahead passes a fixed object

Pick an object that does not move. Count when the car ahead passes it. You should reach it at "three".
