Driving through a flood.

We’ve just made a repair to a vehicle with water damage so we thought this piece of advice may just help.
Never forget that floods are inherently dangerous, and before you try driving through one, you should be absolutely certain that it’s safe to do so.And even if you think the flood is relatively safe, remember that driving through deep water can cause serious damage to your car which might not be covered by your insurance company.
Watch other cars driving through to get a feel for how deep the flood is. If there are no other cars around, don’t risk it – there may be submerged obstacles, or the water might be fast-flowing, which could sweep your car away. If you’re in any doubt whatsoever, turn around and find another route.
If you do opt to drive on, though, make sure your path is clear right the way through to the other side of the flood. Don’t drive into the water when there is still another car driving through the flood. They might stop, which would strand you in the water.
Try and keep the car at the highest point on the road, if it’s safe to do so, so that it’s as far out of the water as it can get.
Don’t drive too fast, as this might cause you to aquaplane. Instead, find a steady speed you’re comfortable with.
Once you’ve accelerated up to that speed, try not to slow down, if you can help it. Any reduction in speed can cause water to flow back into the radiator grille and be ingested into the engine, or even to be sucked up by the exhaust pipe. Either will likely cause expensive damage, potentially even writing the car off.
As you reach the other side of the flood, drive out of the water carefully, and test your brakes before continuing your journey.
