Aquaplaning Dangers Highlighted In Online Movie

BY Azfar Hashim

A new online movie has been launched, to educate drivers about the risks associated with aquaplaning

In the dramatic clip, (available to view on Tyresafe's YouTube Channel) a car with low tyre tread depth can be seen aquaplaning on a flooded road surface, dangerously continuing to travel in a straight line despite the driver turning the steering wheel furiously in an attempt to make the car change direction. “Our latest movie and animation illustrate perfectly why it’s so important to regularly check your tyre tread depth at this time of year,” comments Stuart Jackson, chairman, TyreSafe. “Not only are braking, cornering and acceleration all affected by low tread depth, but in heavy rain, there’s a real risk of aquaplaning which could cause you to lose control of your vehicle, placing yourself, your passengers and other road users at an increased risk of being involved in an accident.”

Adequate tread depth is important for safety in wet conditions as the tread grooves help to remove the water from the contact patch between the tyre and the road surface. As the tyre’s tread depth wears down, its ability to remove water from the road decreases meaning that grip levels are reduced and stopping distances are extended. In extreme circumstances when the tyre has insufficient tread depth to clear the water properly, increased water pressure causes the tyres to lift on top of the water surface and lose contact with the road surface. During this dangerous aquaplaning situation any input from the driver such as pressing the brake or turning the steering wheel has no effect on the vehicle, leaving it at an increased risk of being involved in an accident.

Checking the condition of your tyre tread depth can be done quickly and easily by taking the coin test. To perform the test, simply place a 20-cents coin into the main tread grooves of your tyre. If the outer band of the 20-cents coin is obscured when inserted into your tread, then your tyre is above the legal minimum limit. Meanwhile if the outer band of the 20-cents coin is visible, then your tyre tread depth may be dangerously low and should be inspected immediately by a tyre professional.
