Published On:

The National Weather Service reported heavy fog through 10 a.m. Sunday for Indiana’s higher elevations, as well as Mercer, Venango, Forest, Lawrence, Butler, Clarion, Jefferson, Beaver, Allegheny, Armstrong, Washington, Westmoreland, and Indiana counties. The report was released at 5:35 a.m.

“As the skies have cleared this morning, patchy dense fog is predicted over a large portion of the region. At times, visibility may be diminished to less than a quarter mile. This fog will last till daybreak and then gradually clear by mid-morning. Drivers need to be ready for patches of severely diminished visibility. The weather service advises travelers to take these decreased visibilities into consideration this morning.

Fog safety: Tips from the weather service for safe travels

The following safety advice should be kept in mind if you must drive in foggy conditions:

Slow down:


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

Visibility is important.


  • Ensure your vehicle is visible to others by using low-beam headlights, which also activate your taillights. If available, employ your fog lights.

Steer clear of high beams:


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

Keep your gaps safe:


  • Keep a considerable following distance to account for sudden stops or shifts in traffic patterns.

Remain in your lane:


  • Use the road’s lane markings as a guide to remaining in the correct lane.

Strategy for zero visibility:


  • In cases of near-zero visibility due to dense fog, initiate your hazard lights and locate a secure spot, such as a nearby business parking area, to pull over and come to a halt.

Restricted parking possibilities


  • 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.

Following these weather service guidelines will help you drive more safely in foggy circumstances, reducing the chance of accidents and putting your health first.
