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 in fog becomes unavoidable, remember these safety tips:

Reduce speed:

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

Visibility priority:

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

Stay in your lane:

To ensure you are staying in the correct lane, use the road’s lane markings as a guide.

Visibility near zero:

In cases of near-zero visibility due to dense fog, initiate your hazard lights and locate a secure spot, such as a nearby business parking area, to pull over and come to a halt.

Limited 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 more safely, reducing the risk of accidents and ensuring your well-being.
