Driving Through Floods.

Driving Through Floods.

Britain has experienced, if that’s the right word, the most rain in 248 years and it’s not showing any sign of stopping. This presents more and, for many, new challenges when driving on our soaked highways. Here’s some advice for dealing with any flooded roads drivers might find themselves encountering.

For starters and rather obviously, it is best to avoid flooded roads altogether. Basically, if a driver knows a road is at risk he shouldn’t go down it at all. Nevertheless, we must all prepare for the unexpected. Essentially, for most cars except massive 4×4’s, fifteen centimetres is about as much as the average car can manage.

The answer is to get out and check. The water will usually be most shallow on the crown of the road. If it is deep there then it will be deeper along the sides. Try to establish visual markers; the height of the water against traffic signs for example, or indeed, stranded vehicles. If in doubt, don’t.

When it comes to road speed through water then less is definitely more in safety terms. Enter the water at no more than four or five miles per hour. Tick-over in first gear may be faster than this so there’s a need to slip the clutch in order not to go too quickly. Keeping the engine revving prevents water sneakily entering via the exhaust pipe.

It is necessary to go this slowly because the car needs to push the water aside, creating a depression in front to prevent the engine sucking in water through its air intake. The faster you go the more the water is disturbed then a bow wave is created and there is more likelihood that the engine will flood. If there are other cars coming in the opposite direction then wait for a turn. Their actions could result in your engine becoming flooded.

Once through, gently apply the brakes to remove excess water from the pads. If the engine sounds odd then it might have swallowed some water. Driving a misfiring car could cause more damage. Stop immediately and seek help. Ideally of course, avoid driving altogether if your district is afflicted with floods; but if you must go out then try to remember these wise words.
