With a foot of water, you need to be really careful. You could drive your car into a lake or sinkhole you aren’t able to see because it is obscured by the surface of the water.
If you are going to drive through this water regardless of the warnings, drive as slow as possible to keep water from splashing into the air intake.
I had to drive home in Miami during the last Hurricane Irene in 1999, and it was in more than a foot of water. It took me a really long time to get home, but when I finally made it, I had done no harm to my car. I am still driving that same car, and have had no issues with any suspension components.
While driving through water like this, it’s really frustrating to drive as slow as you have to drive to prevent damage, but in a case like this, you can’t go too slow. If you are driving an automatic, you will need to use the brake to control your speed since even at idle speed, you could easily go too fast.
If your car can survive driving in a heavy downpour, it can survive driving in a foot of water, just make sure you always control your speed. Drive as if you are in a boat in a “no wake” zone, but much slower. If you see any white caps in the wake you leave behind, you are going too fast. The wake you leave with your car should be extremely slow and gentle.
oldbodyman: “When you are moving the air is trapped under the hood keeping the water from getting around the engine.”
OMG, that has to be one of the most outlandishly BOOOOOOOGUS things I have ever heard. oldbodyman, what kind of car are you driving that has an air tight hood?
