Explanation

Three factors determine the distance it takes to stop your vehicle: perception time, reaction distance, and braking distance. All three factors are affected by weather, visibility, and your mental and physical condition, as well as the condition of your brakes, tires and the pavement. Therefore, it is important to adjust your driving speed to the weather and road conditions to ensure that you have enough time to stop if something is in your path.
