Fog safety: Tips from the NWS for safe travels

If a dense fog advisory is issued for your area, it means that widespread dense fog has developed and visibility often drops to just a quarter-mile or less. These conditions can make driving challenging, so exercise extreme caution on the road, and if possible, consider delaying your trip.

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

Reduce speed:

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

Visibility priority:

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 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 remaining in the correct lane.

Visibility near zero:

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 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.
