flooded roadTurn Around - Don't Drown

The Centers for Disease Control and Prevention report that over half of all flood-related drownings occur when a vehicle is driven into hazardous flood water. The next highest percentage of flood-related deaths is due to walking into or near flood waters. People underestimate the force and power of water. Never drive around the barriers blocking a flooded road. The road may have collapsed under that water.https://www.weather.gov/safety/flood-turn-around-dont-drown
