Hydroplaning Hydroplaning is dangerous. So much water can build up under your tires that theycan actually ride on 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 no contact with the road. Hydroplaning doesn't happen often. But it can if your tires haven't much tread if the pressure inone or 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 couldbe hydroplaning. Hydroplaning usually happens at higher speeds. There just isn't a hard and fast rule about hydroplaning. The best advice is to slow down when it is raining. Driving Through Deep StandingWater NOTICE: If you drive too quickly through deep puddles or standing water, water can come in through your engine's air intake and badly damage your engine. Never drive through water that is slightly lower than the underbody your vehicle. If you of can't avoid deep puddles or standing water, drive through them very slowly. Some Other Rainy Weather Tips 0 Turn on your low-beam headlamps -- not just your parking lamps -- to help make you more visible to others . Besides slowing down, allow some extra following distance. And be especially careful when you pass another vehicle. Allow yourself more clear room ahead, and be preparedto have your view restricted by road spray. 0 Have good tires with proper tread depth.
