What should drivers do if roads are wet and there is water on the road?

When driving on wet roads, it is crucial for drivers to reduce their speed to minimize the chances of hydroplaning. Hydroplaning occurs when a vehicle's tires lose traction and rise on top of a layer of water, preventing effective steering and braking. By slowing down, drivers ensure that their tires maintain better contact with the road surface, allowing for improved control and safer maneuvering.

In wet conditions, maintaining a safe speed is essential for not only the driver’s safety but also for the safety of others on the road. Slowing down gives drivers more reaction time to adjust to slippery conditions, obstacles, or sudden stops that may be necessary. It also helps to increase the effectiveness of braking, making it less likely for a vehicle to skid or lose control.

The other options suggest actions that do not effectively address the primary concern of maintaining control on wet roads. For instance, applying brakes before encountering water can lead to more sudden starts and stops that may exacerbate skidding. Asking pedestrians to move aside does not address the driving situation directly, and simply driving at regular speed disregards the increased risks associated with wet road surfaces.
