Inspection & Enforcement Program
Pennsylvania operates weigh stations and mobile enforcement units. PSP performs Level I through Level III inspections. The PA Turnpike has enforcement at service plazas and toll facilities. Pennsylvania's inspection volumes are among the highest in the nation.
Weight Limits & Oversize/Overweight
Pennsylvania follows federal weight limits of 80,000 lbs GVW on Interstate highways. The state has specific weight limits on the PA Turnpike and on numerous bridges on the extensive secondary road system. Many Pennsylvania bridges are weight-restricted, requiring careful route planning for heavy loads.
Pennsylvania-Specific Requirements
- Pennsylvania has a very large number of weight-restricted bridges on secondary roads. PennDOT's bridge restriction list is essential for route planning.
- The PA Turnpike uses all-electronic tolling; commercial vehicles need E-ZPass or are billed by mail at a higher rate.
- Pennsylvania enforces an anti-idling law limiting diesel vehicle idle time to 5 minutes in most areas.
- The state requires specific permits for loads exceeding 80,000 lbs even on designated overweight corridors.
- Philadelphia has specific truck routing requirements and parking restrictions within the city.
