Connecticut Trucking Regulations

Connecticut follows the federal 80,000 lbs GVW limit on interstate highways but has stricter limits on many state roads — some bridges and routes are posted at 73,000 lbs or lower. The Connecticut Department of Transportation (CTDOT) State Traffic Administration issues oversize/overweight permits. Single-trip permits start at $35. Connecticut enforces weight limits at weigh-in-motion systems and portable scales along I-95, I-91, I-84, and the Merritt/Wilbur Cross Parkways. The Merritt Parkway prohibits all commercial vehicles, and the Wilbur Cross Parkway has a 13'6" height restriction that regularly traps unwary truckers. Connecticut's permit system is increasingly online through the CT PERMITS portal. Overweight fines start at $200 and escalate rapidly with excess weight.

Connecticut is a key link in the Northeast I-95 corridor, one of the most congested freight routes in the nation. The state enforces strict truck lane restrictions on portions of I-95, particularly through Bridgeport and New Haven. Peak-hour truck restrictions apply on the Gold Star Memorial Bridge (I-95 over the Thames River). Connecticut participates in the Northeast Diesel Collaborative and follows EPA emissions standards. The state has adopted California's Advanced Clean Trucks rule, requiring increasing zero-emission truck sales starting in 2027. Commercial vehicles must have reflective marking meeting FMCSA standards — enforcement is stricter in the Northeast corridor due to dense traffic. Connecticut State Police Commercial Vehicle Division conducts approximately 25,000 inspections annually.

Connecticut does not currently have highway tolls for trucks but has considered implementing them. The state charges a Highway Use Fee on all carriers registered in or traveling through Connecticut — effective since 2023, it charges $0.026 per mile for trucks over 26,000 lbs. Carriers must register through the Department of Revenue Services (DRS) and report miles quarterly. Failure to register carries a $500 fine per violation. Connecticut commercial vehicle registration through DMV ranges from $400-$900 based on gross weight. The state requires all CMVs to carry a current registration card and have valid USDOT markings. Connecticut enforces IFTA and IRP requirements. The state income tax is progressive, ranging from 3% to 6.99%, making it one of the higher-tax states for owner-operators.
