Precautionary / Preparedness Actions

  • If possible, wait for temperatures to warm above freezing before traveling.

  • Slow down and give 3 times as much space as normal between vehicles.

  • Shaded areas may be more slippery than unshaded areas.

  • Use low beams. High beams reflect back fog making visibility worse for you and other drivers.

  • Fog makes objects appear farther away than they are.

  • Be ready for low visibility by keeping your headlights clean.

  • Don`t use cruise control. Most crashes occur because the driver is going too fast for weather conditions.
