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 driving through fog becomes inevitable, remember these safety guidelines:

Moderate your speed:

Slow down and allow extra travel time 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 lights, as they create glare, making it more difficult for you to see what’s ahead of you on the road.

Maintain safe gaps:

Maintain a generous following distance to account for abrupt stops or shifting traffic patterns.

Stay in your lane:

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

Zero visibility strategy:

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 no designated parking area is available, pull your vehicle as far off the road as possible. Once stationary, deactivate all lights except the hazard flashers, engage the emergency brake, and release the brake pedal to ensure your tail lights remain unlit, minimizing the chance of other drivers colliding with your stationary vehicle.

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.
