Why is it not safe to be in a car during even a shallow flood?
 
A vehicle can be swept away in just 18 to 24 inches of water, so even shallow floods are dangerous. Flood water moves very fast, and even large vehicles are under threat of losing control. You can drown if your car is swept away into flood water.

Remember that you do not want to turn on any lights until you know that gas and electrical lines are safe. Having a flashlight can help you check lines if it is dark outside or if power has been disrupted.
