What you need to tow commercially in New York

If you operate a tow truck in New York State, you need a Commercial Driver License (CDL) with a towing endorsement, not a standard driver license. The endorsement is called the T endorsement, and it tells the state and law enforcement that you have passed the knowledge and skills tests specific to towing operations.

You cannot legally tow for money or as part of a business without this endorsement, even if you hold a regular CDL. The T endorsement is separate from your base CDL and requires its own written test and practical exam.

New York's Department of Motor Vehicles (DMV) administers both the CDL itself and the towing endorsement. If you already hold a CDL from another state, you can transfer it to New York and add the T endorsement, but you will still need to pass New York's towing knowledge test.

Key Takeaways

  • You must hold a CDL with a T endorsement to operate a tow truck for money in New York; a regular driver license is not sufficient.
  • The T endorsement requires passing a written knowledge test covering towing equipment, safety procedures, and New York towing regulations.
  • You must also pass a practical skills test in a tow truck, which includes vehicle inspection, coupling and uncoupling, and on-road operation.
  • If you already have a CDL from another state, you can transfer it to New York but must still pass the state's towing knowledge test to add the T endorsement.
  • Your employer may require additional training or certifications beyond the CDL T endorsement, such as heavy wrecker certification or specific equipment training.

Steps to get your CDL with T endorsement in New York

Start by holding a valid New York driver license (Class D) for at least two weeks before you can take the CDL written test. You do not need a CDL yet—you are building toward it. Visit your local DMV office and request the CDL Information Packet, which includes the study materials for all CDL classes and endorsements, including towing.

Study the towing section of the CDL manual. The written test covers coupling and uncoupling procedures, weight distribution, brake systems on towed vehicles, securing cargo, and New York-specific towing laws. You can take the written test at any DMV office that administers CDL tests. Bring your valid driver license, proof of New York residency, and your Social Security number or ITIN.

Once you pass the written test, you receive a Commercial Learner Permit (CLP). With this permit, you can practice driving a tow truck with a licensed CDL holder in the passenger seat. You must hold the CLP for at least one day before you can take the practical skills test, though most people practice for several weeks.

Schedule your practical exam at a DMV office that offers CDL testing. Bring a tow truck that meets New York's specifications, a licensed CDL holder to supervise, and your CLP. The exam includes three parts: vehicle inspection (you walk around the truck and explain safety checks), coupling and uncoupling (you physically connect and disconnect a trailer), and an on-road driving test lasting 30 to 45 minutes.

What the towing knowledge test covers

The written test for the T endorsement focuses on the mechanics and safety of towing. You will answer questions about proper coupling procedures, how to inspect a tow truck before operation, weight limits and load distribution, and how to find a disabled vehicle to your truck.

The test also covers brake systems—specifically how air brakes work on heavy trucks and trailers, and how to recognize brake failure in a towed vehicle. You will see questions about New York regulations for tow trucks, including lighting requirements, marking requirements for wide or long loads, and rules for operating on highways.

The exam is typically 40 to 50 questions, and you must score at least 80 percent to pass. You can retake the test if you do not pass, but you must wait one day between attempts. The DMV does not charge a retesting fee.

The practical skills test: what happens during the exam

The practical exam takes place at a DMV testing facility and lasts about one hour total. You will perform three distinct tasks that the examiner watches and scores.

Vehicle inspection: You walk around the tow truck and explain what you are checking. The examiner asks you to identify lights, mirrors, coupling mechanisms, safety chains, and brake components. You must demonstrate that you know what to look for and why each part matters for safe towing.

Coupling and uncoupling: You physically connect a trailer to the tow truck, then disconnect it. The examiner watches for proper procedures: positioning the truck, lowering the coupling, securing safety chains, and connecting air and electrical lines. You then reverse the process to uncouple. Mistakes here—such as forgetting to find chains or failing to connect air lines—result in automatic failure.

On-road driving: You drive the tow truck with a trailer on public roads or a closed course, depending on the testing location. The examiner evaluates your ability to accelerate, brake, turn, back up, and park with a trailer attached. You must demonstrate smooth operation and awareness of the trailer's length and width.

Insurance and vehicle requirements for the exam

The tow truck you use for the practical exam must be registered and insured in New York. The truck must have a valid inspection sticker and meet all safety standards. If you do not own a truck, your employer or a training school may provide one for the exam.

Your truck must be equipped with a functioning coupling system, safety chains, and air brake lines if it is a heavy-duty truck. The examiner will not test you in a vehicle that does not meet these standards.

You will also need to show proof of insurance at the testing facility. The insurance must cover the specific truck you are using and must be active on the day of the exam. If your employer owns the truck, their insurance policy must list you as an authorized operator.

After you pass: maintaining your T endorsement

Once you pass both the written and practical tests, the DMV issues you a CDL with the T endorsement printed on the card. Your CDL is valid for five years in New York, and the T endorsement renews with it.

To renew your CDL, you must visit a DMV office before the expiration date. You will need to pass a new medical examination (a Department of Transportation physical) and pay the renewal fee. You do not need to retake the written or practical tests unless the DMV has suspended or revoked your CDL.

Your employer may require additional training beyond the state CDL, such as heavy wrecker certification, accident recovery procedures, or specific equipment training. These are separate from the T endorsement and vary by company. Ask your employer what certifications they require before you start the job.

If you already have a CDL from another state

If you hold a CDL from another state and move to New York, you can transfer it without retaking the written and practical tests—but only if your current CDL is valid and you have not had it suspended or revoked. Visit a DMV office with your out-of-state CDL, proof of New York residency, and your Social Security number.

The DMV will issue you a New York CDL that mirrors your out-of-state license, including any endorsements you already hold. However, if you want to add the T endorsement in New York and did not have it in your previous state, you must pass New York's towing knowledge test. Some states do not offer a towing endorsement, so this is common.

You will not need to take the practical exam again if you already passed one in another state, but you must pass the written test for the T endorsement specifically. Schedule the test at your local DMV office.

Frequently Asked Questions

Can I tow with a regular driver license if I own the tow truck?

No. New York law requires a CDL with a T endorsement to operate a tow truck for any purpose—whether you own it, work for a company, or operate it independently. Ownership does not change the requirement. Towing without the proper license can result in fines, license suspension, and criminal charges.

How long does it take to get the T endorsement after I pass the written test?

You can take the practical exam as soon as one day after passing the written test, since you only need to hold the Commercial Learner Permit for one day. However, most people practice for several weeks before attempting the skills test. The entire process from written test to passing the practical exam typically takes four to eight weeks.

What if I fail the practical exam?

You can retake the practical exam after waiting one day. There is no fee for retesting. Many people pass on the second or third attempt. Focus on the area where you struggled—coupling procedures, on-road handling, or vehicle inspection—and practice that specific skill before your next test.

Do I need a medical certificate to get the T endorsement?

Yes. To obtain a CDL in New York, you must pass a Department of Transportation physical examination performed by a certified medical examiner. The exam checks your vision, hearing, blood pressure, and ability to operate a commercial vehicle safely. You must bring the completed medical certificate (Form MCSA-5875) to the DMV when you explore for your CDL.

Can my employer train me on the job instead of requiring the CDL first?

No. You must obtain your CDL with T endorsement before you can legally operate a tow truck, even during training. Your employer cannot legally allow you to tow without the proper license. Many tow companies offer paid training or tuition reimbursement to help you obtain the CDL, so ask about that benefit during hiring.
