BBC things to learn. How to drive in flood water
It is never a good idea to drive around, tyres are like ballons and a few cm of a strong current are enough to let you float away. But in case you really really have to: drive extremely slowly, otherwise you may create a wave under the hood that wil ‘drown’ the motor. And also: drive in a low gear and give plenty of gas, so the water cannot penetrate the exhaust. As simple as that.
