Q:

# At what speed does hydroplaning occur?

A:

Hydroplaning can occur at any speed whenever a road is wet. While higher speeds increase the risk of hydroplaning, vehicles traveling at lower speeds are at risk any time there is at least 1/10 of an inch of water on the road.

Hydroplaning occurs when a car's tires pass over a wet surface and are unable to displace enough water on the road to establish traction. This causes the car to skid and slide, giving the driver minimal control over the vehicle. Vehicles traveling faster than 35 miles per hour are more likely to experience hydroplaning, so it is best to travel at slower speeds in rainy conditions. Keeping tires properly inflated also helps reduce the risk of hydroplaning.

The formula for speed is s = d/t, where s equals the speed, d is the distance covered and t is the time it took to cover the distance. The formula for finding the instantaneous speed at a specific point is found by taking the derivative of the speed equation.

Speed measures how fast an object is moving, whereas acceleration is how much the speed of an object changes during a specified period of time. If an object is speeding up, it has a positive acceleration, whereas an object slowing down has a negative acceleration.

Speed and velocity share many similarities, speed is a scalar property while velocity is a vector property. A vector is a scalar quantity with a direction attached to it.
