Massachusetts Trucking Regulations

Massachusetts follows the federal 80,000 lbs GVW limit on interstate highways. The Massachusetts Department of Transportation (MassDOT) Highway Division issues oversize/overweight permits. Single-trip permits start at $40. Massachusetts has strict weight limits on many state roads and historic bridges — the state maintains a bridge sufficiency database. MassDOT operates weigh stations along I-90 (Mass Turnpike), I-95, and I-91. The Registry of Motor Vehicles (RMV) enforces commercial vehicle regulations. Overweight fines in Massachusetts are steep — starting at $500 for the first offense. The state is known for low-clearance overpasses, particularly along the Storrow Drive corridor in Boston (10'0" clearance) where truck strikes occur regularly.

Trucking in the Boston metro area requires special planning. Many bridges, tunnels, and overpasses have clearance restrictions below 13'6". Storrow Drive and Memorial Drive explicitly prohibit commercial vehicles. The Ted Williams Tunnel (I-90) has hazmat restrictions. The Sumner and Callahan Tunnels have height and weight limits. Boston's street layout (colonial-era streets that predate urban planning) creates tight turns and narrow delivery access points. The city enforces delivery time windows in many commercial districts. Massachusetts has adopted the Advanced Clean Trucks rule requiring zero-emission truck sales beginning in 2028. The Mass Turnpike (I-90) charges trucks $4.55-$19.70 for full-length crossing depending on axle count.

Massachusetts requires annual safety inspections for all commercial vehicles at authorized inspection stations — one of the strictest inspection states. Emissions testing is included in the annual inspection. The state enforces IFTA and IRP requirements. Massachusetts requires intrastate carriers to register with the Department of Public Utilities (DPU) for operating authority. The state follows federal HOS and ELD regulations. Massachusetts has a comprehensive anti-idling law: no vehicle may idle for more than 5 minutes (310 CMR 7.11). Fines start at $100 for first offense. State police and local environmental officers enforce the anti-idling law. The Massachusetts Environmental Police also conduct vehicle emissions enforcement.
