Braking distance is the distance a vehicle travels from the moment the brakes are applied until it comes to a complete stop. This distance is influenced by several factors, including the vehicle's speed, the condition of the brakes, and the type of road surface. For example, wet or icy roads can increase braking distance significantly. Additionally, the weight of the vehicle and the reaction time of the driver also play crucial roles. A heavier vehicle or a driver who takes longer to react will generally have a longer braking distance. Understanding these factors is essential for safe driving and accident prevention.
