Driving in the Fog:

• Slow down; allow extra time to reach the destination

• Use low beams and fog lights, if applicable

• Never use high beams, which cause glare

• Engage 4-way flashers when visibility is near-zero

• Increase following distance to account for sudden stops

• Stay in the proper lane by following the lines on the road

Consider the “three-second rule” for maintaining distance in bad weather: You should be able to count to three before you pass what the vehicle in front of you passed.

In extremely dense fog, the NWS recommends:

• Turn on hazards, pull into a safe location such as a rest area or parking lot, and stop

• If there is no safe location to pull into, pull off to the side of the road as far as possible and:

     Turn off all lights except hazards

     Set the emergency brake and remove foot from brake pedal to ensure tail lights are not illuminated.

Fog in mountain valleys is especially prevalent in autumn and spring; if the air has enough moisture, fog will form as night progresses.
