Tips for Drivers Caught in a Flash Flood

Sept. 17 -- Even as Hurricane Isabel approaches, high water is already becoming a road hazard, and drivers are running into deep trouble.

In spite of many daring rescues, not everyone is saved. The National Weather Service estimates flash floods take 110 lives every year. Half those victims die trapped in their cars.

Water rescue experts say the last thing you should do in the event of a flash flood is to sit in your car and let it fill up with water. Get out right away, before the car sinks. Do not expect there to be an air pocket to save you.

"The first thing you do is try to relax," said Sgt. Al Greco, of the Hillsborough County, Fla., Sheriff's Office. "Second thing to do, take off your seat belt. After that, roll your window down, get out of the car. Do not try to ride it down to the bottom."

Good Morning America Consumer Correspondent Greg Hunter tested out a worst-case flash flood scenario with help from the sheriff's department. Hunter sat in a car during a simulated flash flood, but he had an air supply and was surrounded by expert divers.

Many don't realize the tremendous power of rising water. In just two feet, the average car will bob up and down like a cork, completely out of your control. But in a flash flood, your car will not sink right away. You usually have a few minutes to act.

Believe it or not, your best exit is not the door. Opening the door will let in more water, making the car sink faster. Go for the window instead, experts say. Power windows will not stop working immediately.

"In fresh water they'll work up to 30 minutes," Greco said. "We've pulled cars out before where the wipers are still going, headlights are still going. In salt water you have about a minute before the salt water hits the battery and will short the battery out at that time."

Underwater rescue experts have a handy acronym for motorists to keep in mind, POGGO. It stands for: First, pop your seat belt. Next, open a window. Then grab your baby and go.
