Hydroplaning happens when your tires encounter more water than they can scatter, so they lose contact with the road and skid along the water's surface. The water pressure in front of the tire forces a layer of water underneath the tire, reducing friction and causing the driver to lose control of the car.

Why are wet roads slippery?

When it rains, the water on a road causes a loss of friction. As tires move over a wet surface, the water fills in the tiny pits in the road surface, effectively smoothing out the surface. As a result, the normal heat and friction created is decreased, leading to a surface that is more slippery than when dry.
