Staying safe

Never drive into floodwater, because twelve inches of moving water can carry away most cars

It is never safe to drive or walk into flood waters, says the National Weather Service. Six inches of fast-moving water can knock over an adult, and twelve inches of rushing water can carry away most cars.

Key takeaway

If you meet a flooded road, turn around. Do not drive around a barrier. If water starts to rise where you are, get to higher ground immediately and follow evacuation orders.

Water depthWhat it can do (NWS)
6 inches of fast-moving waterCan knock over an adult.
12 inches of rushing waterCan carry away most cars.
2 feet of rushing waterCan carry away SUVs and trucks.

Why cars are not safe

Over half of flood-related drownings occur when a vehicle is driven into hazardous floodwater, according to the CDC as cited by the NWS. Water may be deeper than it looks and may hide hazards.

Barriers and closed roads

Never drive around the barriers blocking a flooded road. The road may have collapsed under the water.

When water starts to rise

Avoid flood waters at all costs and evacuate immediately when water starts to rise. If you are in a flood-prone or low-lying area, get to higher ground immediately. If told to leave, go right away. Lock your home and, if time allows, shut off utilities and appliances.

If you are trapped

If you are trapped by moving water, get to the highest possible point and call 911 if you can.

Electrical hazards

Stay out of basements or rooms where water covers outlets or submerges cords. Get out if you notice sparks or buzzing, crackling or popping sounds.

What this guide does not cover

The NWS pages we used do not say what to do if your car stalls in water, so we do not give advice on that. Call 911 if you are in danger.

Common misconception
A road that looks passable may not be. Water can be deeper than it appears and the road beneath may have collapsed.
