Course Outline

Use the following to calculate stopping distance:

Stopping Distance = Reaction Time Distance + Braking Distance

  • Braking distance is the distance traveled while you’re braking to a stop. It depends on two factors: speed and drag.
  • Drag is the amount of friction between the tires and the surface of the terrain. For example, mud has more drag than dirt. A hard, dry surface has more drag than a hard, wet surface; and ice has very little drag.

The graph gives stopping distances at various speeds. Note, however, that your stopping distance could be different depending on your speed and the surface conditions.
