Hydroplaning: What Is It and How To Avoid It

Driving on wet roads is challenging for several reasons, such as reduced grip level, low visibility and many other factors. One of the dangers of driving on wet roads is the phenomenon called hydroplaning. It occurs when there is too much water on the road. And when it happens, the vehicle loses traction. Hence, it can be very dangerous, especially if the vehicle is at high speed. Read on as we provide you with all the information related to hydroplaning, including its definition, causes and preventive measures.

What is Hydroplaning?

Hydroplaning refers to the loss of traction that occurs when a vehicle's tyres encounter more water than they can disperse, causing the tyres to ride on a thin layer of water instead of maintaining contact with the road surface. It results in a loss of control, making it difficult for the driver to steer, brake, or accelerate effectively.

To better understand hydroplaning, it is crucial to grasp the underlying science. When driving on wet roads, the water accumulates on the surface, creating a thin film that can prevent tyres from effectively gripping the road. As a vehicle approaches this water film, the tyre treads attempt to channel the water away through their grooves. However, hydroplaning can occur if the volume of water exceeds the tyre's capacity to disperse it.

Factors Contributing to Hydroplaning

Hydroplaning is influenced by various factors, each of which can significantly impact the likelihood and severity of the phenomenon. Let's explore some of the key factors to consider.

1. Speed

Speed plays a critical role in hydroplaning incidents. As your vehicle's speed increases, the chances of hydroplaning also rise. It is because higher speeds cause the tyre treads to be less effective in dispersing water, leading to reduced traction and increased vulnerability to hydroplaning.

2. Tyre Tread Depth

The depth of your tyre treads is vital in maintaining proper traction on wet roads. Tyres with worn-out or insufficient tread depth are more prone to hydroplaning. It is crucial to regularly inspect the vehicle’s tyres and ensure they meet the recommended tread depth for optimal safety.

3. Tyre Inflation

Proper tyre inflation is essential for maintaining good traction. Underinflated tyres create a larger contact patch with the road, increasing the risk of hydroplaning. Conversely, overinflated tyres reduce their contact area, potentially compromising grip. Regularly check and maintain the recommended tyre pressure for a safe driving experience.

4. Water Depth and Road Conditions

The depth of water on the road directly affects the likelihood of hydroplaning. Deeper pools of water pose a higher risk, particularly if they are accumulated in ruts or tyre tracks. Additionally, the condition of the road surface, such as the presence of oil, debris, or uneven textures, can also contribute to hydroplaning incidents.

5. Vehicle Weight and Size

The weight and size of your vehicle impact its susceptibility to hydroplaning. Heavier vehicles tend to have a greater potential for hydroplaning due to increased momentum and higher tyre loads. It is essential to consider this factor when driving larger vehicles or carrying heavy loads.

Dangers of Hydroplaning

Hydroplaning poses significant dangers to drivers and passengers, including the following.

• Loss of Control: Hydroplaning reduces the driver's ability to control the vehicle, making it difficult to steer, brake, or accelerate effectively.

• Increased Stopping Distance: With reduced traction, the stopping distance of a vehicle significantly increases, increasing the risk of collisions.

• Reduced Visibility: Hydroplaning often leads to water spray, obscuring the driver's vision and making it challenging to navigate safely.

• Vehicle Damage: Hydroplaning can cause damage to tires, wheels, and other vehicle components due to the loss of control and sudden jolts experienced during the process.

• Accidents and Injuries: The loss of control during hydroplaning can result in accidents, leading to injuries or even fatalities.

What To Do If Your Vehicle is Hydroplaning?

During hydroplaning, it's crucial to remain calm and take immediate action to regain control of your vehicle. Here are the tips to follow if your vehicle is hydroplaning.

• Stay Calm: Panicking can worsen the situation. Stay calm and focused on regaining control of your vehicle.

• Avoid Abrupt Movements: Do not make sudden or aggressive movements with the steering wheel, brakes, or accelerator. Abrupt actions can cause skidding and further loss of control.

• Maintain a Steady Grip: Keep a firm grip on the steering wheel with both hands to maintain control and be prepared for any sudden movements.

• Do Not Slam the Brakes: Avoid slamming the brakes as it can lock the wheels and make it harder to regain traction. Instead, apply gentle and steady pressure on the brakes.

• Ease Off the Accelerator: Gradually release pressure on the accelerator to slow down the vehicle. It helps reduce speed and regain control.

• Steer Straight: Keep the steering wheel straight and avoid making sharp turns until control is regained. Steering into the skid can make the situation worse.

• Focus on a Safe Path: Look for an open and clear path in the direction you want to go. Keep your eyes on the road and steer towards it gradually.

• Regain Traction: As the vehicle slows down, the tyres may regain contact with the road surface. You will feel the steering become responsive again. Once traction is regained, you can start making controlled manoeuvres.

• Resume Normal Driving: Once you have regained control, adjust your speed to match the road conditions and continue driving cautiously.

How to Prevent Hydroplaning

Now that you know the factors contributing to hydroplaning, let's delve into effective preventive measures to help you stay safe on wet roads. By following these guidelines, you can significantly reduce the chances of hydroplaning incidents.

1. Slow Down and Drive Defensively

Reducing your speed is crucial when driving on wet roads. Slowing down allows your tyres more time to disperse water, enhancing their grip and minimising the risk of hydroplaning. Additionally, maintaining a safe distance from the vehicle ahead and anticipating potential hazards will provide you with ample time to react and prevent accidents.

2. Ensure Proper Tyre Maintenance

Regular tyre maintenance is essential for optimal traction and safety. Here are some key aspects to consider.

• Tyre Tread Depth: Monitor and maintain the recommended tread depth for your tyres. Consider replacing worn-out tyres promptly.

• Tyre Inflation: Check your tyre pressure regularly and inflate them to the recommended levels. This will ensure proper tyre contact with the road surface.

• Tyre Rotation: Rotate your tyres regularly to promote even wear and extend their lifespan.

3. Invest in Quality Tyres

Choosing high-quality tyres with reliable wet-weather performance is a wise investment. Look for tyres specifically designed to enhance traction on wet surfaces. These tyres often feature advanced tread patterns and special compounds that improve grip and reduce the risk of hydroplaning.

4. Avoid Sudden Manoeuvres

When driving on wet roads, sudden manoeuvres such as hard braking, quick acceleration, or sharp turns can increase the likelihood of hydroplaning. Maintain a smooth and controlled driving style to minimise risk. Gradual and gentle inputs to the steering, braking, and acceleration will help maintain stability and control.

5. Keep a Safe Following Distance

Maintaining an adequate following distance is essential to ensure your safety and minimise the risk of hydroplaning accidents. By keeping a reasonable distance from the vehicle ahead, you provide yourself with ample time to react and manoeuvre safely, even in unexpected situations.

6. Avoid Standing Water

Whenever possible, try to avoid driving through standing water or large puddles. If you are unable to avoid such large puddles, reduce the vehicle’s speed significantly when tackling standing water on roads.
