How should you handle driving in heavy rain?

When driving in heavy rain, the safest approach is to slow down, increase your following distance, and use your headlights. Heavy rain reduces visibility and can create slippery road conditions. By slowing down, you allow yourself more time to react to obstacles and reduce the risk of losing control of the vehicle.

Increasing your following distance is crucial because, in wet conditions, the stopping distance can be significantly longer than on dry roads. It ensures you have enough space to react should the vehicle in front of you suddenly stop or slow down. Using headlights is important for improving visibility for both yourself and other drivers. It allows you to see the road better while also making your vehicle more visible to others, enhancing overall safety.

The other options are less safe because speeding up can lead to loss of control and could put you at greater risk of accidents. Maintaining a constant speed without regard for conditions does not take into account the need for adjusted driving behaviors in adverse weather. Frequently changing lanes can be dangerous in heavy rain as it can create confusion and reduce your overall control of the vehicle.
