How do weather conditions affect stopping distances?

Weather conditions significantly impact stopping distances, particularly in wet or slippery situations. In wet conditions, the road surface becomes slick, which reduces the friction between the tires and the pavement. This diminished traction means that when a driver applies the brakes, the vehicle is less able to slow down effectively, leading to longer stopping distances. Factors such as the type of tire, the depth of water on the road, and the vehicle's speed also play critical roles in how much the stopping distance is affected.

While the assertion that sunny conditions can improve traction is often true, it's too absolute to say they always reduce stopping distances—variations in road conditions, tire maintenance, and vehicle load can all influence this outcome. Hence, while sunny weather generally means better stopping power, it cannot be stated definitively that it always results in shorter stopping distances. Understanding the effects of different weather conditions on stopping distances is crucial for safe driving practices.
