A Commercial Driver's License (CDL) is required in Connecticut to operate commercial motor vehicles over 26,000 lbs GVWR, buses carrying 16 or more passengers, or vehicles placarded for hazardous materials. Connecticut CDL fees start at $60 for a 4-year license. Three CDL classes are available: Class A for tractor-trailer combinations, Class B for single large vehicles, and Class C for passenger and HazMat vehicles. First-time applicants must complete Entry Level Driver Training (ELDT) through an FMCSA-registered provider before taking the skills test. All interstate CDL holders must maintain a valid DOT Medical Certificate. Test your knowledge with the Connecticut CDL knowledge test, then pass the skills test — pre-trip inspection, basic vehicle control, and road driving — to earn your license.
Any combination of vehicles with a GCWR of 26,001 lbs or more, provided the GVWR of the towed vehicle exceeds 10,000 lbs.
Any single vehicle with a GVWR of 26,001 lbs or more, or any such vehicle towing a vehicle with a GVWR not exceeding 10,000 lbs.
Any single vehicle or combination not covered by Class A or B, designed to transport 16 or more passengers including the driver, or required to be placarded for hazardous materials.
TSA security threat assessment and fingerprinting required. Required for fuel and chemical hauling in Connecticut's dense Northeast corridor. Note: certain HazMat loads are restricted from specific Connecticut highway segments and tunnels.

Required for vehicles carrying 16 or more passengers. Used for CTtransit, casino shuttle, and commuter transportation operations.
Requires P endorsement. Connecticut requires background check and fingerprinting for school bus operators.
Required for double and triple trailer combinations on designated routes. Connecticut permits standard double trailers on designated highways. Class A CDL required.
Combination H and N endorsements for HazMat tank vehicles. TSA background check applies. Common for heating oil and fuel tanker operators — Connecticut has high residential fuel oil demand.
Entry Level Driver Training (ELDT) is required by federal regulation (49 CFR Part 380, effective Feb 7, 2022) for first-time Class A or B CDL applicants and for adding H, P, or S endorsements. Connecticut has registered CDL training providers in the Hartford, New Haven, and Bridgeport areas. Find registered providers at tpr.fmcsa.dot.gov.

Connecticut CDLs are valid for 4 years. Your DOT Medical Certificate must be renewed separately — typically every 24 months for interstate drivers. Renew your CDL at any Connecticut DMV office before expiration. Connecticut's 30-day CDL transfer window for new residents is shorter than most states — act quickly after establishing residency.
The Merritt Parkway (Route 15) and Wilbur Cross Parkway are strictly prohibited to commercial trucks and vehicles over 7 feet 6 inches wide. Violations carry significant fines. These parkways have low overpasses (as low as 10 feet clearance) that cause serious accidents every year. Always use truck-rated GPS and confirm your route before traveling in southwestern Connecticut.
Yes. Connecticut allows 22,400 lbs on a single axle and 36,000 lbs on a tandem axle — both higher than the federal standards of 20,000 and 34,000 lbs respectively. This allows operators to carry heavier payloads per axle on Connecticut roads, which can be beneficial for distribution operations based in the state.
Connecticut's location on the I-95 Northeast corridor makes it a significant hub for regional distribution. Major CDL opportunities include LTL and TL freight for NYC/Boston corridor carriers, heating oil and fuel delivery (high demand given Connecticut's residential fuel oil dependence), retail and grocery distribution (Walmart, Stop & Shop, Big Y distribution centers), and pharmaceutical logistics from the New Haven and Hartford biotech clusters.
