What Are the Dangers of Driving Through a Flooded Street?

Floodwater often covers potholes, broken pavement, and debris that you cannot see. A tire can drop into a hole or hit a submerged object, causing a blowout or loss of steering. The road surface underneath may be washed out entirely, leaving a gap that can swallow a vehicle.

Even a few inches of water can hide a deep depression or a missing section of asphalt. You might feel the ground give way while you are moving, which can leave you stuck or worse. Without a clear view of the road, you are essentially driving blind over an unknown surface.

• Potholes and broken pavement hidden underwater
• Debris like branches, trash, or rocks
• Washed-out sections of the road
• Slippery surfaces from oil and mud
• Downed power lines that may be electrified

Floodwater moves with surprising force. Just six inches of fast-moving water can knock a person off their feet, and a foot of water can float a small car. Two feet of water can carry away most vehicles, including trucks and SUVs, according to general safety guidance.

The current is often stronger than it looks, and it can push your vehicle sideways or into obstacles. Once the water reaches the bottom of your doors, the vehicle can become buoyant and drift. Trying to drive through can put you and any passengers in a life-threatening position.

If you cannot avoid a flooded street, proceed with extreme caution. Slow down, shift into a low gear, and keep a steady speed to create a bow wave. Avoid stopping in the water, and test your brakes after you exit. If the water is moving or deeper than the bottom of your wheels, turn around.

Before you drive, check your surroundings for downed power lines and never drive over them. If you are in Cincinnati, keep a local map or GPS handy to find alternate routes. Your safety is more important than reaching your destination, so do not take unnecessary risks.
