Slow down by at least 5 or 10 miles an hour.
At certain speeds, your car can hydroplane, lifting off the ground, and you will be driving on a layer of water. If that happens, don’t panic; just slow down until the car feels normal again.
Avoid driving through flooded areas.
It will be difficult to gauge the water’s depth. This is dangerous in itself. And if water gets sucked into the air-intake valve and then the engine, the car will probably shut off.
Feather the brakes after you’ve driven through a puddle.
And make sure you take your foot off the gas. This creates heat and friction, which will help dry the brakes.
