What affects a driver’s reaction time and stopping distance?

If a driver is tried their reaction time will be longer than a driver who is alert. Alcohol and certain drugs can make the reaction time longer. Distractions in the car, such as a smartphone, will also increase a driver’s reaction. And because all of these factors increase the reaction time they also increase the thinking distance. A driver’s stopping distance can be stopped by wet or icy conditions, worn tires and brakes. This is because wet or icy conditions reduce the friction between the tyres and the road, increasing the braking distance. Worn tyres increase the stopping distance because they reduce the friction between the tyre and the road. And work brakes also increase the braking distance.
