PennDOT: Tier 2 Vehicle Restrictions in Effect on I-86 and I-90

January 9, 2024

OIL CITY, Pa. – Due to the windy conditions of the winter storm, PennDOT is temporarily restricting certain vehicles on Interstate 86 and Interstate 90 in Erie County.

Vehicle restrictions reflect Tier 2 of the commonwealth’s weather event vehicle restriction plan and are in effect on the entire length of Interstate 86 and Interstate 90 in Erie County.

Under Tier 2 restrictions, the following vehicles are not permitted on affected roadways:

  • Tractors without trailers.
  • Tractors towing unloaded or lightly loaded enclosed trailers, open trailers, or tank trailers.
  • Tractors towing unloaded or lightly loaded tandem trailers.
  • Tractors towing loaded tandem trailers unless there are chains or other approved Alternate Traction Devices (ADTs).
  • Enclosed unloaded or lightly loaded cargo delivery trucks/box trucks that meet the definition of a CMV.
  • Passenger vehicles (cars, SUVs, pickup trucks, etc.) towing trailers.
  • Recreational vehicles/motorhomes.
  • School buses, commercial buses, and motor coaches regardless of the availability of trains or ATDs.
  • Motorcycles.

The purpose of the restriction is to help ensure the interstates remain open during the most challenging conditions of the winter storm. When conditions improve, PennDOT will remove the travel restrictions.

Restrictions will be communicated via variable message boards, the 511PA traveler information website at, and smartphone apps. Motorists can also sign up for alerts on the website.

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