The distance a vehicle travels during the driver's reaction time, before the brakes are applied.

The distance it travels in this stage is its thinking distance.

The distance a vehicle travels during the driver's reaction time, before braking begins.

During the thinking distance, the driver is reacting and has not yet applied the brakes.

Stopping distance includes both thinking distance and braking distance; braking distance alone is not the total.

To find braking distance, subtract thinking distance from stopping distance. Give distances in metres.

Link road safety explanations explicitly: longer reaction time → greater thinking distance at the same speed.
