Hydroplaning happens when tires lose contact with the road and ride on a film of water. It is most common during the first rain after a dry spell, when roads are slick with accumulated oil. Recognizing the risk and adjusting your driving prevents it.
Reduce speed in rain
The faster you travel, the harder it is for tires to disperse water. Slow down well below the speed limit in heavy rain — hydroplaning can begin at speeds as low as 35 mph when water pools.
Maintain your tires
Worn tires with shallow tread cannot channel water away. Check tread depth and tire pressure regularly. See tire safety and maintenance for how to check both.
If you hydroplane
Ease off the gas, keep the steering wheel straight, and avoid hard braking. Smooth inputs help tires regain contact gradually. Jerking the wheel or slamming the brakes can send the vehicle into a spin.
