How to Get a CDL Permit in Connecticut
Connecticut's commercial learner's permit process costs $16 for the knowledge exam and $10 for the permit itself — and once issued, the CLP stays valid for a full year.
Line up your medical exam and registration first
Complete a physical examination with a Certified Medical Examiner, who determines whether you're medically qualified to operate commercially and notifies the DMV of the results.
Register with the Federal Motor Carrier Safety Administration's Drug and Alcohol Clearinghouse, and self-certify with DMV as to intrastate or interstate operation.
Pass the knowledge test and pay the fees
Pass the General Knowledge test ($16), plus combination-vehicle and air-brake tests if applicable to your training vehicle.
Pay the $10 permit fee to receive your commercial learner's permit, valid for a full year from issuance.
Complete ELDT within the year
Complete entry-level driver training (ELDT) through an authorized provider before applying for your first CDL — a federal requirement since February 2022.
Since the CLP lasts a full year, there's real room to schedule ELDT and the road test without rushing, unlike states with a much shorter CLP window.
The skills test and beyond
Schedule and pass your skills (road) test.
Passing gets you your Class A, B, or C commercial driver's license, with any endorsements reflecting the additional tests you passed along the way.
