    PennDOT Lifts Vehicle Restrictions on Interstates in Northwest Region

    January 26, 2026

    Speed Reductions Remain in Place throughout the Northwest Region

    The Pennsylvania Department of Transportation (PennDOT) has lifted the remaining temporary restrictions on certain vehicles from traveling on interstates in the Northwest Region.

    A vehicle restriction reflecting Tier 4 and later Tier 3 of the commonwealth’s weather event vehicle restriction plan was in place on interstates in the region in connection with Sunday’s winter weather event.

    Speed limits remain restricted to 45 mph for all vehicles, and commercial vehicles must move to the right lane on interstates 79, 80, 86, 90, and 376 in the Northwest Region.

    Additional restrictions are in place on roadways throughout Pennsylvania. Check www.511PA.com for the last updates on travel conditions and restrictions.  

    Although PennDOT crews have been treating roadways, the department’s primary goal is to keep roads passable, and they will not completely free of ice and snow. PennDOT will continue to treat roadways throughout the storm until precipitation stops and roads are clear.

    While PennDOT recommends not traveling during winter storms, motorists can check conditions on more than 40,000 roadway miles, including color-coded winter conditions on 2,900 miles, by visiting www.511PA.com. 511PA, which is free and available 24 hours a day, provides traffic delay warnings, weather forecasts, traffic speed information and access to more than 1,200 traffic cameras.

    511PA is also available through a smartphone application for iPhone and Android devices, by calling 5-1-1, or by following regional X alerts.

    Motorists should always allow plenty of space when driving near plow trucks. Also, for their own safety and the safety of plow operators, motorists should never attempt to pass a truck while it is plowing or spreading winter materials.
