Braking distance is the distance a vehicle travels from the moment the brakes are applied until it comes to a complete stop. This distance can vary based on several factors, including the vehicle's speed, road conditions, and the effectiveness of the braking system. For example, a car traveling at a higher speed will require a longer braking distance compared to one moving slowly. Additionally, wet or icy roads can increase braking distance, making it essential for drivers to maintain a safe following distance to allow for unexpected stops.
