What is the proper following distance rule recommended for normal driving conditions?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

Use the three-second rule — stay at least three seconds behind the vehicle ahead (more in poor conditions)

  1. A Use the three-second rule — stay at least three seconds behind the vehicle ahead (more in poor conditions)
  2. B Stay one foot behind
  3. C Follow at exactly 10 feet
  4. D Stay as close as possible

Why this is the answer

The THREE-SECOND RULE: maintain at least THREE SECONDS of following distance behind the vehicle ahead under normal conditions. DMV/permit rules of the road.

How: when the vehicle ahead passes a fixed object (sign, pole), count 'one-thousand-one, one-thousand-two, one-thousand-three' — if you reach the object before finishing, you're too close. INCREASE the distance (4+ seconds) in poor conditions: rain, snow, fog, heavy traffic, at higher speeds, or when being tailgated. Adequate following distance gives time to react and stop safely, preventing rear-end collisions. Knowing the three-second following rule (and increasing it in bad conditions) is commonly tested.
