Remember back in high school, when driver’s ed classes taught you not only where to place your hands on a steering wheel, but also what to avoid in tough driving weather?
That’s still relevant today. One of the most common risks drivers face in inclement weather is hydroplaning. Here’s exactly what it is, how to avoid it, and what to do if it arrives.
What is Hydroplaning?
Hydroplaning occurs when a tire encounters more water than it can scatter. As speed increases, the tires start to ride up on the layer of water, much like waterskiing. This means the driver can't brake, accelerate, or turn, and eliminates all traction from the tires—and it happens in a matter of seconds.
Hydroplaning can occur at speeds as low as 35 mph, and the likelihood increases when traveling at 55 mph or higher. According to AAA data, cars are at greatest risk during the first 10 minutes of a downpour, especially if the water is more than one-tenth of an inch deep.
“When hydroplaning, you are literally riding on top of water without any control of your vehicle,” said AAA Car Doctor John Paul.
Light rain, however, mixed with oil residue on the road surface, can also create slippery conditions that can lead to hydroplaning.
How Can Drivers Avoid Hydroplaning?
To avoid hydroplaning, experts recommend the following:
Keep tires properly inflated and maintain good tread.
Rotate and replace tires when necessary.
Slow down on wet roads.
Avoid driving in outer lanes where water tends to pool and steer clear of puddles.
Try to drive in the tracks of the vehicle in front of yours for a clear path.
Don't use cruise control.
Avoid sharp turns or hard braking.
Pay attention to a “shushing” sound — it's a signal to slow down.
What Steps Can Drivers Take to Recover from a Hydroplane Incident?
Keep the wheels straight and reduce speed.
Don’t brake. Stay calm and ease off the accelerator. Allow your vehicle to regain traction first.
If you need to brake, simply pump it, and do so gently with a light foot.
Understand anti-lock brakes. If you have anti-lock brakes, you can brake normally, as the technology is programmed to mimic pumping when necessary.
