Hydroplaning happens when a film of water forms between the tire and the road, causing a loss of traction. The best way to prevent it is to keep the tire firmly in contact with the road and to move water out of the way. Slowing gradually gives the tire more time to grip the road and reduces the amount of water pressure under the tire. Avoiding standing water reduces how much water the tire must evacuate, and maintaining proper tire tread ensures the grooves can channel water away instead of letting a slick film form. Together, these actions help you keep traction, steering, and braking response on wet pavement. The other options don’t help: driving fast through water dramatically increases hydroplaning risk; cruise control keeps a constant speed and doesn’t react to changing road conditions; pumping the brakes on wet roads isn’t a reliable or effective way to remove water and can reduce control, especially with ABS.
