On Wednesday at 5:11 a.m. the National Weather Service issued a dense fog advisory in effect until 9 a.m. for Shelby, Talladega, Clay and Randolph counties.

The weather service states, “Visibility one quarter mile or less in dense fog.”

“Low visibility could make driving conditions hazardous,” says the weather service. “If driving, slow down, use your headlights, and leave plenty of distance ahead of you.”

Guidance from the weather service for navigating foggy conditions

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 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 also activate your taillights. If available, employ your fog lights.

Avoid high-beams:

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

Keep a safe distance:

Keep a considerable following distance to account for sudden stops or shifts in 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 situations of near-zero visibility due to dense fog, activate your hazard lights and seek a secure location, such as a nearby business’s parking lot, to pull over and come to a 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 precautions from the weather service, you can navigate foggy conditions more safely, reducing the likelihood of accidents and ensuring your personal safety.
