Fog safety: Tips from the NWS for safe travels

If you must drive in foggy conditions, keep the following safety tips in mind:

Moderate your speed:

• Slow down and allocate extra travel time to reach your destination safely.

Visibility matters:

• Ensure your vehicle is visible to others by using low-beam headlights, which also activate your taillights. If available, employ your fog lights.

Avoid high-beams:

• Refrain from using high-beam headlights, as they create glare that impairs your visibility on the road.

Keep your distance:

• Leave a safe distance between you and the vehicle in front of you to account for sudden stops or changes in the traffic pattern.

Stay in your lane:

• Use the road's lane markings as a guide to remaining in the correct lane.

Zero visibility strategy:

• In extremely dense fog where visibility is near zero, the best course of action is to first turn on your hazard lights, then simply pull into a safe location such as a parking lot of a local business, and stop.

Limited parking options:

• If there is no parking lot or driveway to pull into, pull your vehicle off to the side of the road as far as possible. Once you come to a stop, turn off all lights except your hazard flashing lights, set the emergency brake, and take your foot off of the brake pedal to be sure the tail lights are not illuminated so that other drivers don't mistakenly run into you.

By adhering to these recommendations from the NWS, you can navigate foggy conditions with greater safety, mitigating the risk of accidents and prioritizing your well-being.
