WHAT HAPPENS TO A CAR DURING A FLOOD?*
Water weighs 62.4 lbs. per cubic foot and typically flows downstream at 6 to 12 miles an hour.
When a vehicle stalls in the water, the water's momentum is transferred to the car. For each foot the water rises, 500 lbs. of lateral force are applied to the car.
But the biggest factor is buoyancy. For each foot the water rises up the side of the car, the car displaces 1,500 lbs. of water. In effect, the car weighs 1,500 lbs. less for each foot the water rises.
Just two feet of water will carry away most automobiles!
Driving through flooded areas is extremely dangerous.
STAY SAFE: KEEP OUT OF FLOODED AREAS!
