Avoid Flooded Roads

Turn Around, Don’t Drown!®

• Avoid walking or driving through flood waters.
• Do not drive over bridges that are over fast-moving floodwaters. Floodwaters can scour foundation material from around the footings and make the bridge unstable.
• Just 6 inches of moving water can knock you down, and one foot of moving water can sweep your vehicle away.
• If there is a chance of flash flooding, move immediately to higher ground.
• If floodwaters rise around your car but the water is not moving, abandon the car and move to higher ground. Do not leave the car and enter moving water.
• Avoid camping or parking along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.

Driving Precautions during Heavy Rain and Flooding

• Always exercise caution on roadways during periods of heavy rain: use headlights whenever you use windshield wipers, reduce speeds and maintain a safe distance between vehicles.
• Know your location and do not become distracted while driving. If you need public safety assistance, you need to be able to provide your specific location.
• If you encounter high water, turn around and drive to a safe spot. Call the police non-emergency number – 301-279-8000 to report the situation to emergency personnel.
• ever drive around a street barricade.
• If your vehicle is trapped in high water call 9-1-1 for rescue. Get out and go to higher ground if you can safely do so.
• Six inches of water can sweep a person off their feet and rocks, tree limbs and other debris can be caught in moving water and be dangerous to you when walking, wading or swimming through flood waters.
• If you have to walk or wade through flood water, use a stick to poke the ground in front of you to determine depth and any underwater debris.

For emergencies, call 911 immediately.
