Hydroplaning or aquaplaning happens when the tires of a vehicle lose traction on a wet roadway, causing the car to drift like a sled until the wheels gain traction again. As one might imagine, hydroplaning is extremely dangerous, since the vehicle is out of the driver's control while it slides. During rainy or slushy weather, drivers need to be aware of the risk of hydroplaning, and it is important to drive carefully in these conditions to avoid this dangerous driving situation. There are also some vehicle maintenance tips which can reduce the risk of hydroplaning.

The tires of a vehicle are extremely important, since they connect the vehicle with a roadway. The better the traction between the tires and the road, the more control a driver has. Traction is greatly improved by treads which help to grip the road. Treads also wick away water when drivers navigate in wet conditions. When tires travel too quickly, they cannot push water away quickly enough, and they may start skidding on the surface of the water, which will cause hydroplaning.

In rainy conditions, people should drive slowly, because high speeds increase the danger of hydroplaning. Drivers should also avoid pools of water and puddles on the roads, as these pools can be deeper than they look, and they could cause a car to hydroplane. Drivers should be especially careful on bridges, since water often pools on one section of the bridge. It is also important to keep tires properly inflated, which increases the potential for traction, and to check for tread wear and replace tires in a timely fashion.

If your vehicle starts hydroplaning, do not jerk on the wheel or slam on the brakes. While a car is hydroplaning, the driver has little control over its trajectory, and these actions can cause the car to move violently and potentially dangerously. The best thing to do is to let up on the gas and to gently guide the tires with a movement of the wheel, ideally in the direction of the side of the road so that if the car skids, it will skid out of the way of traffic. If a driver absolutely must brake, it should be done gently; in a car without antilock brakes, pump the brakes.

By using caution in wet conditions or avoiding them altogether, you can prevent a hydroplaning experience. You should also look out for other drivers who might be in trouble when you're driving in inclement weather, as a hydroplaning car could easily slam into you, potentially causing serious damage. Hydroplaning can also happen to aircraft during taxiing and takeoff, so pilots should beware as well.
