The National Weather Service issued a dense fog advisory at 4:34 a.m. on Tuesday in effect until 9 a.m. for Pike and Barbour counties.

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

“Low visibility could make driving conditions hazardous,” states 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

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 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:

• 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 staying 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.

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 remain unlit, minimizing the chance of other drivers colliding with your stationary vehicle.

By adhering to these weather service precautions, you can navigate foggy conditions more safely, reducing the likelihood of accidents and ensuring your personal safety.
