A truck on its way from Warren to New Castle caused flat tires in vehicles over four counties.

According to Pennsylvania State Police, a McClymonds Supply and Transit Company truck lost pieces of its load — small pieces of scrap metal — along the way.

Motor Carrier Safety Assistance Program (MCSAP) personnel discovered the violation as there were multiple vehicles disabled with flat tires along Routes 62, 6, 227, 8, 80, 79, and 422 in Warren, Venango, Mercer, and Lawrence counties between 8 a.m. and noon Monday, Sept. 10.

State police in Warren, Franklin, and New Castle participated in the investigation. PennDOT assisted with the sweeping of those roadways.

Anyone whose tires were punctured from the incident is asked to contact McClymonds — (724) 368-8040 — Clint Hancox.
