In the picture, a blue car travels behind a red one. At a minimum, how much space should the blue car's driver allow?

Correct answer: A gap of at least 3 seconds.

Answer options

  1. AA gap of about 1 second
  2. BA gap of about half a second
  3. CA gap of at least 3 seconds Correct

Why

The basic minimum is 3 seconds of following time; an easy check is to count the seconds after the red car passes a fixed marker. Leave extra room in rain or fog, and remember that 1 second is dangerously close.
