Rain in the UK is not a surprise, but sometimes the amount of rain we receive can make things difficult. After a deluge of water or a long period of rain the water level can rise on a road.
The level of water on a road can be hard to determine in the drivers chair. If you want to drive through the water there are a few strategies you should learn about before attempting to do so. You do not want to be stranded in the road because you could not make it. Checkout tips for driving through flooded areas in Huntsville for more info
You can use landmarks to determine the level of water on the road. For example road signs, markers, or even kerbs allow you to ascertain the depth. If you feel it is unsafe to cross the flooded area you can wait until another vehicle takes the plunge. By allowing someone else to go first you are able to tell the depth of the water, and establish if driving on is worth the risk to your vehicle.
Even when the rain on the road is a couple of centimetres caution still needs to be made in reducing your speed. If you go the speed limit you could still be entering a scenario in which the tyres are unable to grip the surface. A hydroplane could result in which you skid over the water and it could cause a loss of control.
Deep water can infiltrate your engine, especially if it is deep enough to get into the air intake or cylinders. When water enters the engine it will stop, it will not start again, and you are going to have to pay for the repairs. Air intake height changes from car to car. A good estimation of its height is the car lights. If the rainwater on the road is higher than your headlights you should not cross.
When you establish that the rainwater is not too deep to pass you will want to remain in first gear. You will need to rev the engine, but remain at low speed. In a manual vehicle you can keep depressing the clutch to help rev the engine. In an automatic apply the throttle.
Aim to drive through on the crown of the road as the water will be shallowest at this point, and be wary of drivers coming the other way who could be travelling too fast, as they could easily swamp your vehicle with their bow wave.
Once through the hazard, apply your brakes several times to allow them to dry off and to check that they are still working effectively before continuing on your journey.
Driving through a heavily flooded road requires considerable caution and adequate preparation, however if you are at all unsure about your chances of crossing through successfully, then it is best to turn around and find an alternative route.
