Navigating fog: Safety tips by the NWS

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 matters:

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.

Keep your distance:

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 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.

Limited parking options:

If no parking area is available, pull your vehicle as far to the roadside as possible. Once stationary, turn off 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 precautions from the NWS, you can navigate foggy conditions more safely, reducing the likelihood of accidents and ensuring your personal safety.
