When you are traveling at 55 mph on dry pavement, how far will your vehicle go from the moment you spot a hazard until it stops?

Correct answer: Roughly a football field's length.

Answer options

  1. ARoughly twice your vehicle's length
  2. BRoughly half a football field's length
  3. CRoughly a football field's length Correct

Why

At 55 mph on a dry road, the distance covered while you notice the hazard, react and brake adds up to roughly 400 feet, about the length of a football field. Large vehicles need far more room to stop than most drivers expect, so leave plenty of space ahead.
