Fog safety: Tips from the NWS for safe travels

When a dense fog advisory is issued for your area, it means that widespread dense fog has developed and visibility can plummet to a quarter-mile or less. These conditions pose challenges for travel, so exercise extra caution on the road or consider postponing your trip if possible.

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

Moderate your speed:

Slow down and allocate extra time for your trip to reach your destination safely.

Visibility matters:

Ensure your vehicle is visible to others by using low-beam headlights, which automatically activate your taillights. Utilize fog lights if your vehicle is equipped with them.

Avoid high-beams:

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

Maintain safe gaps:

Maintain a significant following distance to account for abrupt stops or shifts in traffic patterns.

Stay in your lane:

Use the road’s lane markings as a guide to staying in the correct lane.

Visibility near zero:

In cases of near-zero visibility due to dense fog, activate your hazard lights and seek a safe spot, like a nearby business parking lot, to pull over and stop.

No 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.
