What 3 things add up to the total stopping distance of your vehicle?

• A. Perception distance, braking distance, and reaction distance
• B. Acceleration distance, friction distance, gravity distance
• C. Reaction distance, perception distance, and wind distance
• D. Perception distance, reaction distance, and wind distance

Answer: (A)

Total stopping distance is the sum of three parts: perception distance, reaction distance, and braking distance. Perception distance is how far you travel while you notice a hazard and decide to act. Reaction distance is how far you move from the moment you decide to brake to when you actually apply the brakes. Braking distance is the distance you cover after you start braking until the vehicle comes to a stop, and it depends on speed, road conditions, tire grip, and brake effectiveness. Adding these together gives the total stopping distance. The other options mix in terms that aren’t standard components of stopping distance (like wind distance or gravity distance), and while factors like friction influence braking distance, they are not separate components on their own.
