OIL CITY, Pa. - The Pennsylvania Department of Transportation (PennDOT) has implemented temporary vehicle restrictions on highways in Mercer and Lawrence County on Friday morning due to winter weather impacts.

According to 511PA, Tier 3 vehicle restrictions are in place on I-80 in Mercer County between the Ohio state line through I-81 at North Wilkes-Barre, as well as I-376 between I-80 and the PA Turnpike.

In Lawrence County, those same restrictions are in place on I-76 just after the Ohio Turnpike in New Springfield, as well as on I-376 in New Castle between the start and end of the toll road.

Under Tier 3 restrictions, no commercial vehicles are permitted on the road except for loaded single trailers with chains or approved alternate traction devices. 

Additionally, all school buses, commercial buses, motor coaches, motorcycles, RVs/motorhomes, and passenger vehicles towing trailers are prohibited from the affected roadways.

Speed limits have also been reduced to 45 miles per hour until the restrictions are lifted.
