When a driver sees a problem ahead, their vehicle will travel some distance while the driver reacts to the situation
What is the braking distance
The vehicle will then go some distance further while the brakes are working to bring it to a halt
What is the stopping distance
Stopping distance = thinking distance + braking distance
What is a reaction time
