Connecticut adopted the Federal Commercial Motor Vehicle Safety Act of 1986, and is part of a nationally uniform system of classifying, testing, and licensing commercial vehicle drivers.

When is an Connecticut CDL Required

You need an Connecticut CDL when you operate the following vehicles:

CLASS A – Applies only to “combination” vehicles with a Gross Combination Weight Rating (GCWR) more than 26,000 pounds, and the Gross Vehicle Weight Rating (GVWR) of the vehicle being towed is more than 10,000 pounds. A driver with a Class A CDL (plus any appropriate endorsements) can also operate all vehicles included in Class B, C, and D (below)

CLASS B – Includes single or combination vehicles where the GVWR of the single vehicle is more than 26,000 pounds. The vehicle being pulled must not be more than 10,000 pounds. A driver with an Connecticut Class B CDL (plus appropriate endorsements) can also legally operate all vehicles in Class C or D.

CLASS C – Any single vehicle, or combination of vehicles, that meets neither the definition of Group A nor that of Group B as contained in this section, but that either is designed to transport 16 or more passengers including the driver, or is used in the transportation of materials found to be hazardous for the purposes of the Hazardous Materials Transportation Act and which require the motor vehicle to be placarded under the Hazardous Materials Regulations (49 CFR part 172, subpart F).
