  Hydroplaning (road vehicle) - Wikipedia, the free encyclopedia
Hydroplaning (sometimes aquaplaning) in a road vehicle is an effect similar to planing in a boat.
A layer of water between the rubber tires of a road vehicle and the road surface (or between airplane wheels and the runway) reduces the friction with the tires.
In a typical hydroplaning situation, increasing water pressure in front of the wheel means that the amount of water being dispersed by the tread is less than the amount being forced under the wheel.

 Controlling Speed or dealing with stopping a vehicle
Vehicle Braking distance is the distance it takes the vehicle to stop once you hit the brakes.
Traction is the friction between the tires and the road.
Hydroplaning is more likely if tire pressure is low or the tread is worn.

Rain is most dangerous when it falls after a long, dry spell on to roads that have become polished and smooth: the rain blends with oil and rubber-dust deposits on the road surface to form a highly dangerous skid mixture.
Hydroplaning (called aquaplaning in Europe and Asia) occurs when water on the roadway accumulates in front of your vehicle's tires faster that the weight of your vehicle can push it out of the way.
Hydroplaning science - Hydroplaning is the result of your tires moving quickly across a wet surface - so fast that they do not have sufficient time to channel that moisture away from the center of the tire.

 Fire Fighter Fatality Investigation Report F2003-19 | CDC/NIOSH
The victim responded to the call in his POV and was heading east on a two-lane paved road, toward the fire department, when, according to the State Police report, he drove over a large pool of water which caused him to hydroplane and lose control.
Although the victim’s speed at the time of the hydroplaning and subsequent crash is unknown, shortly before the crash, he had passed a vehicle that was traveling at approximately 40 mph, thus he likely was going in excess of 40 mph.
To avoid hydroplaning, the driver must be aware of the environmental conditions that increase the potential for this event such as a heavy downpour or standing water on the road.

 Hydroplaning Tyres on Wet Roads - MotorPoint   (Site not responding. Last check: 2007-11-02)
You're driving on a wet stretch of road and all of a sudden it feels as though your vehicle has a mind of its own.
Of course, your vehicle isn't possessed; it has "caught a wave." You're hydroplaning — your tyres are no longer in direct contact with the road as they are riding on top of the water that has pooled on the road.
Hydroplaning can occur when a combination of speed, tyre wear, tyre inflation or the depth of water on the pavement causes the tyres to lose traction.

 Controlling Speed
This is the distance your vehicle travels from the time your eyes see a hazard until your brain recognizes it.
Hydroplaning can occur at speeds as low as 30 mph if there is a lot of water.
Vehicles going the same direction at the same speed are not likely to run into one another.

 hydroplaning
Since hydroplaning can result in a complete loss of traction and vehicle control, you should always reduce speed, paying attention to the traffic around you.
The rear end of your vehicle may feel a little squirrelly (loose, giving you the sensation that it has moved to one side or the other), especially in a high crosswind.
If your vehicle’s tires are still in partial contact with the road surface, you should be able to regain control of the vehicle in the same way that you would on snow or ice.

 Spotter Safety Guide
Hydroplaning is a major area of concern, and if there is any doubt about the situation, the first response should be to slow down and exercise good judgment.
Water on the roads deep enough to cause hydroplaning may not be obviously visible, so caution must be exercised on any wet roads.
In fact, loss of control of the vehicle on wet roads is possible even when hydroplaning is not involved, if the vehicle is moving too fast for the conditions.

 NPRM on TIRE PRESSURE MONITORING SYSTEM FMVSS No. 138
The conditions that influence hydroplaning include speed, tire design, tread depth, water depth on the road, load on the tires, and inflation pressure.
When a vehicle is overloaded, (too much weight is added for the suspension, axle, and tire systems to carry) and the tires are under-inflated, there is an increased risk of tire failures.
Fatal crash involvements in multi-vehicle crashes on wet roads and fatal crashes with pedestrians and bicyclists were significantly reduced.

 Hydroplaning - Wikipedia, the free encyclopedia
With boats, planing or hydroplaning is a method by which a hull skims over the surface of the water, rather than plowing through it.
With rubber wheeled vehicles, aquaplaning, planing or hydroplaning is a cause of loss of steering control when a layer of water prevents direct contact between the tires and the road surface.
Hydroplane is also a technical term for a submarine wing used to help control depth, analogous to the elevators on the tail of an aircraft.

 Defensive Driving Rule #29: Check for Hydroplaning
Hydroplaning is what happens when the tread on your tires cannot channel all the rain-water out from under your tires - or, from under each patch of tire that is supposed to be resting on the road and providing you with traction.
When hydroplaning, those tire patches are riding on a layer of water instead of pavement.
Remember that not hydroplaning means your tread is removing all of the water that gets between your tires and the road surface (channeling it away).

 The National Road Safety Foundation
Heavy Rains not only diminish visibility, they increase the risk of hydroplaning: when a car traveling at high speeds actually lifts and travels on a thin layer of water that forms between the tire and the road.
Stay to the center of the road to avoid deep water and run-off areas, which can pull you off the road.
Generally, the car pulls in the direction of the blown tire or, if the rear tire is blown, the car may fishtail from side to side.

 Hydroplaning - The Hidden Danger of Driving In the Wet
Of course, your vehicle isn't possessed; it has "caught a wave." You're hydroplaning – your tires are no longer in direct contact with the road as they are riding on top of the water that has pooled on the road.
Hydroplaning can occur when a combination of speed, tire wear, tire inflation or the depth of water on the pavement causes the tires to lose traction.
At higher speeds (50 mph and higher), the wedge of water in front of the tires may pass under the tires and the tires will ride on a cushion of water –; resulting in possible complete loss of traction.

 Manitoba Public Insurance > Driving Tips
In cases where the tires are excessively worn (bald tires) or underinflated, or the water is very deep, you may still hydroplane at slower speeds.
At higher speeds (70 km/h and higher), the wedge of water in front of the tires may pass under the tires and the tires will ride on a cushion of water.
As soon as the tires regain contact with the road surface, brake gently to reduce your speed, re-engage the transmission, resume driving at a slower speed and turn off the hazard lights.

 Tires: Where the Rubber Meets the Road
A great deal is expected from our tires and the vehicle’s well being — not to mention our own — depends upon how well they do their job.
How the vehicle performs, rides, corners and brakes depends upon the choice of tire with which it is equipped.
The “P” stands for passenger vehicle tires, “205” refers to the nominal width of the tire in millimeters, “70” refers to the aspect ratio (ratio of the tire’s height to its width), “R” means radial and “14” refers to the wheel rim’s diameter.
