What you need to do to earn a commercial driver's license in Connecticut

Connecticut requires you to pass a written knowledge test, a skills test, and a medical exam before you can drive a commercial vehicle. You do not have to attend a training school — Connecticut allows you to study on your own and test through the DMV — but most people find a CDL training program helpful because instructors teach you the specific skills the state tests and help you understand the rules that explore only to commercial driving.

The Connecticut DMV oversees CDL licensing. You can find the current testing locations, fees, and required documents on the Connecticut DMV website. Training schools are private businesses; the state does not run them, but it does set the standards for what they must teach if they want to be recognized as approved programs.

Key Takeaways

  • Connecticut requires a written test, a behind-the-wheel skills test, and a medical certificate (CDLIS medical card) before you can get a CDL.
  • You can study for the written test on your own using the Connecticut CDL manual, or attend a training school that covers the material in a classroom.
  • The skills test must be taken in a commercial vehicle, which is why most people attend a training program — the school provides the vehicle and an instructor who can teach you how to handle it.
  • Training programs in Connecticut range from a few weeks to several months depending on the class of license and endorsements you need.
  • You must hold a valid Connecticut learner's permit (CLP) for at least 14 days before you can take the skills test.

The written test and learner's permit

Before you can take the skills test, Connecticut requires you to pass a written knowledge test at a DMV office and receive a Commercial Learner's Permit (CLP). The test covers vehicle inspection, safe driving practices, air brakes (if your vehicle has them), hazardous materials (if you plan to haul them), and other topics specific to the class of truck you want to drive.

You can study using the Connecticut CDL manual, which the DMV provides free online. Many training schools also cover the written test material in their classroom instruction. Once you pass the written test, the DMV issues your CLP, and you must wait at least 14 days before you can schedule your skills test. During this waiting period, you can practice driving a commercial vehicle with a licensed CDL holder in the passenger seat.

The skills test and why training helps

The Connecticut skills test has three parts: a pre-trip vehicle inspection, a backing and maneuvering exercise, and an on-road driving test. All three happen in a real commercial vehicle, and you must demonstrate that you can control the truck safely and follow traffic laws.

Most people attend a CDL training program because the school provides the commercial vehicle for the test, an instructor who teaches you how to handle it, and feedback on the specific maneuvers the state tests. If you try to test without training, you must find your own commercial vehicle and arrange for a licensed CDL holder to be present during the test — which is difficult for most people. Training programs typically charge between $3,000 and $7,000 for a full program, though costs vary by school and by the length and intensity of the course.

Types of CDL training programs in Connecticut

Connecticut has truck driving schools in most regions of the state. Programs vary in length and focus. Some schools offer accelerated programs that run 3 to 4 weeks full-time; others spread the same material over 8 to 12 weeks part-time. A few schools specialize in specific endorsements, such as hazardous materials or passenger transport.

When you compare schools, ask whether the program includes classroom instruction for the written test, behind-the-wheel training, vehicle rental for the skills test, and test scheduling. Some schools bundle all of these; others charge separately. Also ask how many hours of behind-the-wheel instruction you receive and whether the instructor will be with you during your actual DMV skills test or only during practice.

Medical certification and other requirements

Connecticut requires you to pass a medical exam by a certified medical examiner and obtain a CDLIS medical certificate (also called a DOT medical card). This exam checks your vision, hearing, blood pressure, and other health factors to may support you can safely operate a commercial vehicle. The exam costs between $100 and $200 and is valid for two years (or one year if you have certain medical conditions).

You must have your medical certificate before you can get your CLP. Some training schools can refer you to a medical examiner or can tell you where to find one in your area. You will also need a valid Connecticut driver's license, proof of residency, and your Social Security number when you explore for your CLP at the DMV.

Classes of CDL and endorsements

Connecticut issues three classes of CDL based on the weight and type of vehicle you want to drive. Class A covers the heaviest trucks and tractor-trailers; Class B covers medium-duty trucks; Class C covers smaller commercial vehicles. Most training programs focus on Class A because that is the most common commercial license.

You can also add endorsements to your CDL, such as Hazmat (hazardous materials), Passenger (for buses), or Tank (for tanker trucks). Each endorsement requires an additional written test. Some training programs include endorsement instruction; others do not. If you know you will need an endorsement, ask the school whether it covers that material and whether the cost is included in the program fee.

After you pass the skills test

Once you pass all three parts of the skills test, the DMV issues your Connecticut CDL. Your license is valid for eight years. You must renew it in person at a DMV office before it expires, and you must maintain a valid medical certificate throughout the life of your license.

If your medical certificate expires, your CDL becomes invalid until you renew it. Some employers require you to notify them of any traffic violations or medical changes, so keep your employer informed if either occurs. Connecticut also has rules about how many violations you can have before your CDL is suspended, so drive safely and follow all traffic laws.

Frequently Asked Questions

Can I get a CDL in Connecticut without attending a training school?

Yes. You can study the Connecticut CDL manual on your own, pass the written test at the DMV, and then take the skills test. However, you must still provide your own commercial vehicle for the skills test and arrange for a licensed CDL holder to supervise. Most people find this route impractical and attend a training school instead.

How long does it take to get a CDL in Connecticut?

The minimum is about three weeks if you attend an accelerated full-time program and pass all tests on your first try. Part-time programs take 8 to 12 weeks. Add time if you need to retake any test or if you wait for a testing appointment at the DMV.

What happens if I fail the skills test?

You can retake it. There is no limit on how many times you can test, but each attempt costs a fee (usually $100 to $150 at the DMV). Many training schools offer retake instruction at a reduced rate if you fail the first time.

Do I need a medical certificate before I take the written test?

No. You need the medical certificate before you get your CLP, but you can take the written test first and then schedule your medical exam. However, the DMV will not issue your CLP until you have both the passing test score and the medical certificate.

Can I transfer a CDL from another state to Connecticut?

Connecticut recognizes out-of-state CDLs, but you must obtain a Connecticut CDL if you become a resident or want to work for a Connecticut employer. Contact the Connecticut DMV for the specific steps to transfer your license.
