  • Tractors towing unloaded or lightly loaded tandem trailers

PennDOT says vehicle restrictions are in effect at “Tier 3” on the following sections of Interstate 80: From the Ohio Border to Interstate 79 and from Interstate 180 to the New Jersey border. The restrictions mean no commercial vehicles are permitted except loaded single trailers with chains or approved alternate traction devices.
