Flooded Road Safety

Floodwater hides washouts, debris and depth. Choosing another route is the single most useful decision a driver can make. In an emergency, call 911.

Why is floodwater so dangerous?

Moving water carries force that surprises people, and roads under water may be damaged or missing beneath the surface. You cannot see how deep it is or whether the road remains. Vehicles of all sizes can be swept or stalled.

Farm machines may feel heavy and safe, but a loaded trailer, a high center of gravity and soft shoulders can make them unstable in water.

Floods can also develop upstream while the sky above you is clear, so a dry spot is no guarantee that the road ahead is safe.

• Depth and road damage are hidden by the water
• Vehicles of every size can stall or be swept away
• Water may keep rising after rain stops

What does the National Weather Service say to do?

The NWS and other agencies promote the message to turn around and not drive through flooded roads. Check the weather.gov site for the exact wording and advice, and for flood watches and warnings in your area.

Learn the difference between watch and warning as the NWS defines them, and share it with workers.

A washed-out section can be many feet across and invisible under moving water, which is why depth guesses are unreliable.

• Turn around and choose another route
• Never assume you know the depth
• Keep children and passengers away from water
• Check official alerts before each trip

How should you plan before heavy rain?

Look at the forecast and the routes you use. Know which roads and low crossings flood in your area, and have a second route in mind. Move machinery to higher ground if flooding is likely.

Talk with workers about the plan, and agree that nobody is expected to drive through water to finish a job. Keep fuel tanks and phones charged.

Mark flood-prone crossings on a farm map and share it with every driver and delivery person who visits.

• Know which roads and crossings flood in your area
• Have a second route planned
• Move machines to higher ground when flooding is likely

What if you meet water on the road?

Stop well back. Do not enter it to test the depth, and do not follow another vehicle through. Turn around where it is safe to do so and choose another route. If darkness or fog hides the road, slow down and watch for signs of water.

Tell others about the hazard if you can, such as by calling the county road department or emergency management office to report it.

Never drive around barricades or closure signs, because they are placed by local officials who know the road damage.

• Do not follow another vehicle through water
• Do not drive around barricades

What if a vehicle is stalled or caught in water?

This is an emergency. Call 911 and follow what the dispatcher says. Do not enter the water to help another person, because rescuers are trained and equipped for it and bystanders often become victims too.

I am not giving rescue steps here. Ask local fire departments and the American Red Cross about water safety training and what to do if your vehicle is caught in water.

What happens after the water goes down?

Roads may be damaged under the surface, with erosion, holes or weakened pavement even after water drops. Treat flood-affected roads with caution, and watch for debris, mud and downed power lines.

Report damage to local authorities, and have equipment checked before returning it to heavy use. Water can damage brakes, electrical systems and engines.

Check livestock, fuel tanks and chemical storage for contamination or damage, and ask local authorities before moving contaminated material.

• Look for erosion, holes and weakened pavement
• Watch for debris and downed power lines
• Report damage to the county road department

What should farm families discuss?

Include children and teens in the conversation. Explain that streams and ditches can rise quickly, that play near floodwater is dangerous, and that nobody should enter it to retrieve anything.

Review the family emergency plan, including where to go, who to call and how to get information. FEMA, the Red Cross and your local emergency management office have planning resources.

Practice the family plan once a year, so that children know what to do and where to go if water rises.
