Hydroplaning Hydroplaning is dangerous. So much water can build up under your tires that they can actually rideon the water. This can happen if the road is wet enough and you're going fast enough. When your vehicle is hydroplaning, it has little or contact with the road. no Hydroplaning doesn't happen often. But it can if your tires haven't much tread or if the pressure in one or more is low. It can happen if a lot of water is standing on the road. If you can see reflections from trees, telephone poles, or other vehicles, and raindrops "dimple" the water's surface, there could be hydroplaning. Hydroplaning usually happens at higher speeds. There just isn't a hard and fast rule abouthydroplaning. The best advice is to slow down when it is raining. Driving too fast through large water puddles or even going through some car washes can cause problems, too. The water may affect your brakes. Try to avoid puddles. But if you can't, try to slow down beforeyou hit them.
