Safety Tips

  • Reduce speed to allow safe stopping distance.
  • Drive with your headlights on low-beam. Never drive using only your parking or fog lights.
  • Avoid crossing traffic or busy intersections whenever possible.
  • Listen for traffic you cannot see.
  • Use windshield wipers and the windshield defogger to improve visibility.
  • Be patient! Don’t pass long lines of traffic in fog.
  • If visibility diminishes to a point that you can no longer proceed, don't stop in the traveled lanes.
  • Attempt to utilize the closest off-ramp which will afford you a safe location to stop and wait for the fog to clear. Steer to the right and onto the shoulder (further to the right if safe and practical). Turn off your lights and remain stopped until visibility improves.
  • If your car stalls or is disabled, turn off your lights, exit your vehicle and move away from it to avoid injury.
  • Call the Caltrans Highway Information Network at 1-800-427-ROAD for the latest highway condition information
