How to Prevent Hydroplaning While Driving In Rainstorms

The average driver, the one daydreaming, or half asleep, or putting on makeup, or engrossed in NPR, will be taken by surprise when the car suddenly accelerates as it enters into a hydroplane. Yes that's right. It goes faster. And rather fast, mean rather suddenly.

When water settles on roadways, and you come barreling down the highway with limited visibility (hopefully your lights are on), in order for the tires of your vehicle to maintain contact with the road, the tires must displace the water. Like parting the red sea. This task is handled by the tire's treads, if they're not worn. If the treads on the tires are worn, the water will stay right where it is -- as a layer between the wheels of your car and the road. Not good.

When water becomes your new road, the vehicle will "hydroplane". Similar to water skiing but without an engine and a screaming child in the back seat. And that doesn't leave much traction for the tires. The lack of traction between the tires and the road decreases the amount of drag (or resistance) therefore the vehicle gains forward momentum.

Here's how that plays out. You're bee bopping down the road in the rain and hating your boss for making you drive into the office when you could have easily worked from home, and your tires loose contact with the road surface and you and your trusty vehicle go gliding across a sheet of water like an olympic figure skater. If you're lucky, the vehicle will continue moving in the same direction and with the front of the vehicle leading the way. If you're not so lucky, the back of your car will be leading the way.

If this ever happens to you, NEVER, NEVER, step on the brakes. Why? Because stepping on the brakes will prevent the tires from rolling. If the tires aren't rolling, but the vehicle is still moving, then there is no possibility of the tires regaining their traction. With hydroplaning, you have a big hunk of out of control useless mechanical energy parting the waters as it spins along the interstate at high speed. With you in it. Getting dizzy.

What you should do is remove your feet from the gas and the brake pedals. Hold the steering wheel firmly as your vehicle initially picks up speed. Your job at this point is to try and keep the vehicle heading in the same direction as before the hydroplaning began. You do this by turning the wheel ONLY if the car begins to turn first. You want to turn the wheel in the direction the back of the vehicle is moving. Basically, that translates into turning the wheel in the opposite direction of which the car wants to spin. Turn the wheel just enough to compensate for the vehicle wanting to spin/turn. This helps to keep the tires in line with the path of travel.

As the vehicle turns to the left, you turn the wheel to the right. Then as the vehicle changes direction and begins to turn to the right, you turn the wheel to the left. These movements will be large at first, but with each turn they should become smaller and smaller until the vehicle comes to a complete stop, or until the tires regain traction with the road surface.

If the vehicle stops completely before you regain control, you could be facing any direction. If you haven't collided with any other vehicles, calmly and quickly restart the engine if it stopped, and continue driving. Don"t sit there waiting for someone to come crashing into you. If you need to do so, drive your car to the side of the road to regain your composure but do it quickly.

If the vehicle doesn't stop, but instead you gain control, then just keep on going as though nothing happened.

Happy Trails,

Why does my jeep vigorously shake after either going over 50mph or a bump n i'm not talkn about a vibration plz help...tie rods,sway bars, track/control arm, new tires,4x alignment, pwr steer pump

I had the same problem with mine, if u look on the drivers side there is a bracket bolted to the frame that the drag link hooks too. If this bracket is cracked or broken or bolts have come loose or fallen out, your front end will go crazy after htting a bump at any speed over say 25 mph.

Front end Vibration is felt when I hit a bump in the road and it stops when I hit another bump in the road, why is this happening

You need to get this checked out immediately. You are most likely looking for worn out tie rod ends, ball joints and the rest of the steering assembly depending on what you are driving. It is also likely to be a combination of bad parts so make sure shocks or struts and control arm bushings are checked as well.

If you are driving a jacked up truck with 33" or bigger tires it could also be the infamous "death wobble". There's a reason they call it that and you will need to get stabilizers attached to the drag link to eliminate it. They look like long shock absorbers and mount between the frame and the drag link. Hope this helps.

I have a 1993 Jeep Grand Cherokee Laredo. There is a "violent" vibration that occurs only when you are going 40-60 MPH and you hit a bump or pot hole on the highway. The front end begins to...

Vibration from about 40-60 mph is usually attributed to wheel balancing, but the onset when you hit a bump seems to indicate play in the steering linkages (tie rods etc) or suspension members and stabiliser bar rubbers but you had that all checked out, that brings us back to the wheel balancing.

When hitting a bump the vehicle begins to vibrate and must be slowed almost to a stop to regain control

Sounds like it needs a new steering stabilzer. It is like a shock absorber for the steering linkage.

My chevy silverado 2500 shakes like crazy when i hit a bump on the road

Your steering damper that controls the steering system's lateral motion is a shock absorber mounted to the steering components under the vehicle. This is most likely the cause of the shaking. Also inspect the tie rod ends and all other suspension systems for possible failure.
The damper looks like this with the replacement hardware;

If i hit a small bump at 50 mph, front ends shakes so bad,I have to stop truck \r\nalso lots of play in steering

My friend, you have very serious wear in the front end of your vehicle as evidenced by the severe vibration when you hit a bump. The front end steering equipment in your Jeep is very complex requiring special tools and expertise to properly repair. Please get your 1995 Jeep looked at soon by a front end alignment specialty shop in your area. This is a very dangerous condition.

Thank you for your interest in
