Instruction: 
Motorists should not attempt to drive around barricades or drive cars through flooded areas. Even 6 inches of fast-moving flood water can knock you off your feet and a depth of 2 feet will float your car. Never try to walk, swim, or drive through such swift water. If you come upon flood waters, stop, turn around and go another way. Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles.
