Guidance from the NWS for navigating foggy conditions

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 venture out in foggy conditions, keep these safety tips from the NWS in mind:

Reduce speed:

Slow down and allocate extra time for your trip 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 you have fog lights, use them.

Avoid high-beams:

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

Keep a safe distance:

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.

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.

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 are not illuminated, reducing the risk 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.
