During a rainstorm, how much following distance should be maintained from the vehicle ahead?

Maintaining a much greater following distance during a rainstorm is crucial due to the decreased traction and increased stopping distances that wet road conditions create. In ideal driving conditions, a driver might follow the three-second rule, which is a guideline for maintaining a safe distance under normal circumstances. However, in rainy weather, this distance needs to be extended to allow for additional reaction time and braking distance. Wet surfaces can lead to hydroplaning, which significantly reduces a vehicle's control, making it essential to provide more space between vehicles. This extra following distance helps accommodate the longer time it takes to stop and gives drivers time to react if the vehicle in front suddenly stops or swerves. Therefore, the recommendation is to increase following distance to ensure safety while driving in adverse weather conditions.
