Driving Through Flooded Roads in Virginia: Turn Around, Don't Drown

From summer thunderstorms to the remnants of Atlantic hurricanes, Virginia sees its share of fast-flooding roads. A dip that is dry on your morning commute can be a foot deep by evening. It is tempting to think your car can handle a little water, but flooded roads are one of the most underestimated dangers drivers face. Here is how to stay safe when the water rises.

How Little Water It Takes to Be Deadly

The numbers surprise almost everyone. According to the National Weather Service:

• 6 inches of water reaches the bottom of most cars, causing loss of control and possible stalling.

• 12 inches of rushing water can float and carry away a small car.

• 2 feet of moving water can sweep away most vehicles, including SUVs and pickup trucks.

Moving water is the real threat. Just six inches of fast-moving flood water can knock an adult off their feet. And because water hides what is beneath it, you often cannot tell whether the road underneath has washed out entirely.

Over half of all flood-related drownings happen when a vehicle is driven into hazardous water, which makes this the most preventable flood danger of all.

Why Your Vehicle Is No Match for Floodwater

Cars are far more buoyant than people expect. Once water gets deep enough, it lifts the tires off the pavement and the current—not you—decides where the vehicle goes. Even before that point, water pulled into the engine can stall it instantly, leaving you stranded in a rising, fast-moving hazard. Electric and hybrid vehicles are no exception. Four-wheel drive and high ground clearance help on rough terrain, but they do nothing to keep a floating vehicle from being swept downstream—and a stalled engine leaves every vehicle equally helpless.

This is why every emergency agency repeats the same simple rule: Turn Around, Don't Drown.

What to Do When You Encounter a Flooded Road

Before you reach the water

• Never drive past barricades. They are there because officials already know the road is unsafe.

• Slow down and assess. If you cannot clearly see the road surface and how deep the water is, treat it as too deep.

• Turn around and find another route. A longer drive home always beats a water rescue.

If your car stalls or is caught in water

• If water is rising around a stalled car and you can safely exit, abandon the vehicle and move to higher ground.

• If the car is being swept away, get out through a window as soon as you can; cars can fill and sink quickly.

• Call 911 as soon as you are safe.

Wet Roads Are Risky Even Without Flooding

You do not need a full-blown flood to lose control. Standing water and heavy rain cause hydroplaning, where your tires ride on a film of water instead of the pavement. Good tires and reduced speed are your best defense—learn more in our guides to preventing hydroplaning and driving safely in rain and fog. Pushing your speed in these conditions can even rise to the level of driving too fast for conditions, which carries real penalties in Virginia.

After You Drive Through Shallow Water

Sometimes you safely cross a shallow, clearly passable puddle. When you do, dry your brakes by gently pressing the pedal a few times at low speed—wet brake pads can grab unevenly or feel soft and slow to respond. Watch the dashboard for warning lights, listen for unusual sounds, and if the steering or braking feels off afterward, have your vehicle checked before getting back up to speed. Standing water can also hide potholes and debris, so ease through slowly rather than splashing through at speed. When in doubt about depth, though, the safest choice is always to find another route.

Frequently Asked Questions

How many inches of water is dangerous to drive through?

Just 6 inches can cause loss of control or stall a car, and 12 inches of moving water can float a small vehicle. If you are unsure of the depth, turn around.

Is it illegal to drive around a flood barricade in Virginia?

Driving past barricades is both dangerous and can result in citations or rescue fees. Barricades signal that authorities have already determined the road is unsafe.

What should I do if my car stalls in floodwater?

If water is rising and you can exit safely, leave the vehicle and get to higher ground immediately, then call 911. Do not stay with a car that is being swept away.
