What should a driver do after passing through deep water?

After passing through deep water, it is important for the driver to ride the brake gently for a while. This action helps to dry the brake components, which can become wet and lose effectiveness due to the water. Riding the brake means applying light pressure to the brake pedal, which generates heat through friction and effectively helps evaporate the moisture from the brake pads and rotors, restoring normal braking function.

This practice is crucial for maintaining safety on the road, as wet brakes can result in longer stopping distances and decreased overall vehicle control. The other options, while they may seem beneficial in alternative contexts, do not directly address the critical need to ensure the brakes are functioning properly after being exposed to water.
