How should drivers adjust their driving behavior when it begins to rain?

When it begins to rain, adjusting driving behavior is crucial for maintaining safety on the road. Increasing following distance is the correct response because wet roads can significantly reduce tire traction, leading to longer stopping distances. By increasing the space between vehicles, a driver allows for greater reaction time if sudden stops are necessary. This is especially important in rainy conditions where visibility can also be compromised, meaning that both stopping distances and awareness of surroundings must be taken into account.

Driving at the normal speed limit does not account for reduced traction, which can lead to skidding or losing control of the vehicle. Using high beams is not advisable in rain as they can create glare and reduce visibility further. While reducing speed significantly may seem sensible, it's more important to adjust your speed to a safe level rather than just a blanket reduction, combined with the fundamental practice of maintaining a greater following distance.
