Stay safe around flooded roads

Never drive through a flooded roadway or around a road-closure barricade. Water may be deeper or moving faster than it appears, and the roadway underneath may be damaged. If you encounter water covering the road, turn around and choose a safer route.

Turn around, don’t drown.

Get your vehicle ready for wet weather

Prepare before the rain begins:

  • Replace worn windshield wipers.
  • Check your headlights, brake lights, and turn signals.
  • Clean or restore weathered or hazy headlight lenses.
  • Inspect your tires and replace any with worn tread or visible damage.
  • Check tire pressure with a tire gauge. The recommended PSI is usually listed inside the driver’s door.
  • Keep a flashlight, extra batteries, a cellphone charger or power bank, a warm jacket, gloves, and a first-aid kit in your vehicle.

If you purchase fuel at a California gas station, ask the attendant about free air and use of a tire-pressure gauge. Keeping an inexpensive tire gauge in your vehicle is also a good idea.
