What is hydroplaning and how can you reduce risk while responding?

• A. Hydroplaning is a tire failure causing blowout; replace tire.
• B. Hydroplaning is caused by oily surface; drive slowly.
• C. Hydroplaning is a layer of water reduces tire traction; reduce speed and avoid hard braking or sharp steering on wet surfaces.
• D. Hydroplaning is a lack of traction due to dirt; clean tires.

Answer: (C)

Hydroplaning happens when a layer of water builds between the tires and the road, so the tires can’t grip the surface and steering, braking, and acceleration become ineffective. This loss of traction is exactly why the best way to reduce risk while responding is to slow down and avoid abrupt actions on wet roads. Reducing speed helps the tire tread displace water and regain direct contact with the pavement, while gentle braking and steering maintain control instead of pushing the vehicle further into a slick situation. If you sense the vehicle starting to slide—like a loss of steering or a feeling of gliding—ease off the accelerator gradually (don’t slam the brakes), keep the steering smooth in the direction you want to travel, and wait until traction returns before resuming normal maneuvers. Maintaining good tire tread and a larger following distance in wet conditions further lowers the chance of hydroplaning during response.
