Increasing your following distance is particularly crucial during rainy or slippery conditions because these factors significantly affect vehicle traction and braking performance. When the road is wet, the likelihood of hydroplaning increases, which can occur when a vehicle's tires lose contact with the road surface due to water. This reduced traction means that stopping distances are longer, making it important to maintain a greater distance from the vehicle ahead. A larger following distance provides additional time to react to sudden stops or emergencies, contributing to overall road safety.

In contrast, while sunny weather, heavy traffic, and low-light conditions also warrant attention to following distances, the need is amplified in adverse weather situations. This is because the hazards associated with wet or slippery roads present unique challenges that necessitate a more cautious approach to driving.
