CT DOT regulations for commercial motor vehicles
CT Department of TransportationOfficial CT DOT websiteOverview
Connecticut's commercial vehicle enforcement is handled by the Connecticut State Police Commercial Vehicle Enforcement Unit and the Department of Motor Vehicles. As a northeastern corridor state on I-95 and I-84, Connecticut sees significant through-truck traffic. The state participates in multi-state enforcement initiatives with neighboring New York, Massachusetts, and Rhode Island.
Inspection & Enforcement Program
Connecticut operates weigh stations on major highways and uses mobile enforcement units. The state performs Level I through Level III inspections with a focus on the I-95 corridor. Connecticut also participates in the New England Motor Freight Task Force for coordinated multi-state enforcement.
Weight Limits & Oversize/Overweight
Connecticut follows federal weight limits of 80,000 lbs GVW on Interstate highways. On non-Interstate routes, the state has lower weight limits on many roads due to aging infrastructure and numerous weight-restricted bridges. The Merritt Parkway (Route 15) prohibits commercial vehicles entirely. Connecticut has some of the most restrictive local road weight limits in the country.
Connecticut-Specific Requirements
- The Merritt Parkway (Route 15) prohibits all commercial vehicles. Severe fines apply for violations.
- Connecticut has numerous local road weight restrictions. Many roads have posted limits well below federal standards.
- The state enforces strict anti-idling regulations: no more than 3 minutes of idling for diesel commercial vehicles.
- Connecticut requires a state permit for overweight/oversize loads with specific routing through the DOT permit office.
