Thinking distance is the distance a vehicle travels between the time the driver notices a hazard and the moment they start to brake. It is an important part of stopping distance, which also includes the braking distance. Thinking distance depends on the driver's reaction time; factors like tiredness, distractions, and the influence of alcohol or drugs can increase this time. It is also affected by the speed at which the vehicle is moving: the faster the vehicle, the longer the thinking distance. Understanding thinking distance helps you grasp how quickly a vehicle can stop in an emergency.
