Hydroplaning: Why it Occurs and What to Do When It Happens to You

Hydroplaning -- also known as Aquaplaning -- takes place when water gets between the tires of a vehicle and the road surface. Friction is the force used to both propel a vehicle forward, control motion and to bring the vehicle to a stop. Water on the roadway can act as a lubricant, causing the tires to skid uncontrollably in certain weather conditions.

The Dangers of Hydroplaning

Losing control of a vehicle is a hazard that should be avoided at all cost. During a hydroplane, tires lose contact with the surface of the roadway, putting the driver into an uncontrolled skid until one or more tires regain contact with the road or the vehicle collides with another object.

What Is Hydroplaning?

Hydroplaning occurs as water on the surface pools in front of the vehicle. A vehicle in motion tends to push rainwater to the front of the tire. Water displaced by the tires can then get between the rubber and the road surface, causing the vehicle to move in an uncontrolled skid or slide. The beginning of a rain or snowstorm can be the most dangerous time for hydroplaning because oils, gasoline, transmission fluids and other engine liquids that may have leaked from other vehicles and dried to the road surface becomes slick when exposed to rainwater.

How to Avoid Hydroplaning

The most effective prevention tool to losing control of your vehicle is to maintain a safe speed during hazardous conditions. If you do find yourself in an uncontrolled slide, be careful not to overcorrect. If possible, avoid slamming the brakes in favor of waiting for tires to regain grip on the road surface and coming to a controlled stop. 

The Difference Your Tires Make

Your tires’ tread can make the difference when combatting a hydroplane. The grooves of your tires are specially designed to whisk away water in order to keep rubber in contact with the road. When your tires lose tread as a result of common wear, your vehicle becomes more susceptible to hydroplaning when exposed to wet or icy road conditions. Keep your vehicle safe by choosing high-quality tires designed to prevent hydroplaning, and by keeping your tires properly balanced and rotated. Manufacturers recommend rotating and balancing your tires every time you change your oil -- about every 7,000 - 10,000 miles of use.
