Motorists Risking Safety In Flood Water

Dangers Of Driving In Flood Water

Motorists are continuing to put themselves at risk by driving through flood water, the BBC has reported. The Fire Brigade has, therefore, rescued countless drivers from their cars during the recent bad weather. Driving through water is more dangerous than some people assume. Firstly, it can be hard to establish its depth. As such it might look – and indeed be – shallow at one end but far deeper in the middle if the road dips. It can also conceal hazards such as fallen tree branches, etc. If the water is deep it might flood a car's air intake and cause it to stall. It is then unlikely to restart without a mechanic. Furthermore, water can flood the passenger compartment which – even if the car is running – can add so much weight that it becomes hard to manoeuvre. After all, a volume of water measuring one metre cubed weighs one metric tonne. This volume of liquid inside a car can cause enough damage to write it off. Most seriously, in extreme cases a car can be swept into a river by the movement of water over a road. Whereas some people think this is unlikely - a tiny depth of water moving at speed has vast power.

 How To Drive Through Flood Water

There are simple steps that minimise the risk of passing flood water. The first is to estimate its depth by looking for clues such as its height in relation to the kerb, its transparency and – if available – a measuring pole. These are typically found at Fords. Consider the water's speed too. Naturally, if it is to deep or to fast find an alternative route. Whether the road is passable also varies according to the vehicle's specification. A low sports car is less capable than a Range Rover, for example. As a guide, twenty-five centimetres of still water is plenty to challenge the average car. Assuming it is safe to proceed look for the shallowest route. It is also wise to watch another motorist's attempt then learning from his/her experience. To proceed select first – or “low” in an automatic - then leave it in gear and maintain pressure on the throttle. This ensures that gas flows through the exhaust which should stop water being sucked into the engine. Speed can be controlled by simultaneously left foot braking. Furthermore, proceed at low speed to prevent water rising at the front and flooding the engine's air intake. Then - once the flood water is in the rear view mirror - test/dry the brakes with gentle pressure.
