Which of the following increases your risk of crashes in rain?

Using regular tires without tread significantly increases the risk of crashes in rain due to the reduced traction that worn-out tires provide. Tread on tires is essential for channeling water away from the contact surface between the tire and the road. When tires lack sufficient tread, they are more prone to hydroplaning, where the vehicle rides on top of the water instead of making contact with the road. This loss of grip can lead to a loss of control over the vehicle, making it difficult to steer, brake, or accelerate effectively in wet conditions.

In contrast, driving below the speed limit, keeping a safe following distance, and using low beam headlights are all practices that enhance safety in wet weather. Lower speeds can reduce the severity of a crash, maintaining a safe following distance allows for extra reaction time on slick surfaces, and low beam headlights improve visibility during rain, making it easier to see and be seen by other drivers. Thus, maintaining proper tire tread is crucial for preventing crashes in rainy conditions.
