Motorists should not attempt to drive around barricades or drive
cars through flooded areas.

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

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.
