What to do if…
your vehicle is trapped in rising floodwater

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

If water is rising inside the vehicle, get onto the roof immediately and call 911 as soon as you can do so safely. If the vehicle is trapped in rapidly moving water but water is not rising inside, stay inside and call 911.

Do not do these things

  • Do not keep trying to drive through the water.
  • Do not leave the vehicle to test the water’s depth.
  • Do not walk or swim through floodwater to reach another place.
  • Do not climb down from the roof unless rescuers direct you or conditions force an immediate move.
  • Do not delay for bags, documents, or other belongings.
  • Do not touch downed power lines or water that may be in contact with them.
  • Do not assume the road beneath the water is intact.

What to do now

  1. If water is rising inside the vehicle, move onto the roof now. Take your phone only if it is already within reach and will not delay you.
  2. Call 911. Give your location, nearby landmarks, vehicle description, number of occupants, any injuries, and whether the water or vehicle is moving.
  3. If the vehicle is trapped in rapidly moving water and water is not rising inside, stay inside, stop trying to drive, and follow the 911 call-taker’s instructions.
  4. Once on the roof, remain there and make yourself visible to rescuers. Do not enter the floodwater.
  5. Keep everyone together. Tell 911 if children, injured people, or anyone with limited mobility needs help leaving the vehicle.
  6. Tell the 911 call-taker immediately if water starts entering faster, the vehicle shifts, or anyone’s condition changes.

What can wait

Towing, vehicle recovery, repairs, insurance claims, retrieving possessions, and arranging the rest of your journey can wait. Focus only on keeping everyone together, staying out of the floodwater, and helping rescuers find you.

Important reassurance

You do not need to save the vehicle or your belongings. Staying inside when the vehicle is trapped in rapidly moving water, moving to the roof if water rises inside, and following 911 instructions are appropriate immediate actions.

Scope note

This guide covers immediate first steps only. Vehicle recovery, medical assessment, insurance, and travel arrangements may require specialist help after everyone is safe.
