Hydroplaning (also known as aquaplaning) occurs when a layer of water builds up between your vehicle’s tires and the surface of the road. This causes your tires to lose contact with the road, leading to a loss of steering, braking, and traction control.
Why Hydroplaning Happens
Hydroplaning typically occurs when:
- Water on the road is more than 1/10 of an inch deep.
- You’re driving at higher speeds (usually over 35 mph / 55 km/h).
- Tires are underinflated, bald, or worn out.
- The vehicle is lightweight or has poor tire tread design for wet conditions.
Why It’s Dangerous
- Loss of control: Your car may skid or spin.
- Inability to steer or brake: You can’t change direction or slow down safely.
- Higher risk of collisions: Especially in heavy traffic or when turning or braking suddenly.
How to Avoid Hydroplaning
- Slow Down in Wet Conditions
- Drive under the speed limit when it’s raining or the roads are wet.
- Avoid sudden acceleration or sharp turns.
- Check Your Tires
- Ensure tires are properly inflated.
- Replace tires that are bald or have shallow tread (minimum safe tread depth is 2/32 inch; 4/32 inch is better in rain).
- Consider rain-optimized tires if you live in a wet climate.
- Avoid Standing Water
- Steer clear of puddles, especially on outer lanes where water tends to collect.
- Drive in the Tracks of the Car Ahead
- Let other vehicles “clear” the road ahead of you.
- Avoid Using Cruise Control
- It may delay your reaction time and reduce control if you start to hydroplane.
What to Do if You Hydroplane
- Stay calm.
- Ease off the gas pedal gently.
- Do not brake suddenly.
- Steer in the direction you want to go—don’t jerk the wheel.
- Wait until traction returns, then regain control gradually.
