Endorsements are add-ons to your license that let you drive certain vehicle types or perform specific driving tasks

An endorsement is a notation on your driver's license that says you are legally permitted to operate a particular class of vehicle or perform a particular driving function. Without the correct endorsement, you cannot legally drive that vehicle, even if you pass a test. Endorsements are not the same as license classes — they are additions to a class you already hold.

The most common endorsements are for commercial driving (the CDL, or Commercial Driver's License), but states also issue endorsements for motorcycles, hazardous materials transport, passenger transport, and air brake operation. Each endorsement requires its own written test, skills test, or both, and each has its own fee.

You cannot straightforward decide to add an endorsement. You must pass the required tests and meet the medical and background requirements for that endorsement. The process varies by state and by endorsement type, but the general path is the same: study the manual, pass the written test, pass the driving test (if required), and pay the fee.

Key Takeaways

  • Endorsements are separate from your license class and allow you to drive specific vehicle types or perform specific tasks, such as hauling hazardous materials or carrying passengers for hire.
  • The most common endorsement is the Commercial Driver's License (CDL), which requires a written test, a skills test, and a medical certificate from a certified examiner.
  • Each state sets its own endorsement rules, fees, and test requirements, so the process in your state may differ from a neighboring state.
  • You must pass both the written and skills tests for an endorsement before you can legally use it, and some endorsements require a background check or medical clearance.

The most common endorsement: the Commercial Driver's License (CDL)

A Commercial Driver's License is required to operate any commercial vehicle over a certain weight (usually 26,001 pounds or more) or to transport hazardous materials or passengers for hire. If you drive a semi-truck, a school bus, or a tanker truck, you need a CDL. If you drive a delivery van for a company, you may or may not need one, depending on the vehicle weight and your state's rules.

To get a CDL, you must first hold a valid regular driver's license. You then study the CDL manual for your state, pass a written test on general knowledge, pass a written test on the specific endorsement you want (such as hazmat or passenger), and pass a behind-the-wheel driving test in a commercial vehicle. You must also pass a medical examination by a certified medical examiner and obtain a Medical Certificate. The entire process typically takes several weeks to several months, depending on how quickly you schedule your tests and how many attempts you need.

CDL fees vary by state but typically range from $50 to $200 for the license itself, plus the cost of the medical exam (usually $100 to $200). Some states charge per test; others charge one flat fee for all tests. You will need to check your state's DMV website for the exact breakdown.

Motorcycle endorsements and their requirements

A motorcycle endorsement (often called an M endorsement or motorcycle class, depending on the state) allows you to operate a motorcycle on public roads. In most states, you cannot legally ride a motorcycle without this endorsement, even if you hold a regular driver's license.

To get a motorcycle endorsement, you typically must pass a written test on motorcycle safety and rules, and pass a skills test on a motorcycle. Some states allow you to take a Motorcycle Safety Foundation (MSF) course instead of the skills test; completing an MSF course often waives the riding test and sometimes the written test as well. The MSF course usually costs $150 to $300 and takes one or two days.

If you do not take the MSF course, you must bring your own motorcycle to the DMV for the skills test, or use a motorcycle provided by the testing facility (if available). The written test covers topics like braking, turning, protective gear, and road hazards. Fees for motorcycle endorsements are usually $15 to $50, though the MSF course fee is separate.

Other endorsements: hazmat, passenger, and air brake

Beyond CDL and motorcycle endorsements, states offer several others that attach to a CDL or regular license:

  • Hazmat (H) endorsement: Allows you to transport hazardous materials. Requires a written test, a background check, and a Transportation Security Administration (TSA) clearance. Fees range from $50 to $100, plus TSA processing fees. This endorsement is valid for five years.
  • Passenger (P) endorsement: Allows you to operate a vehicle designed to carry 16 or more passengers (including the driver). Requires a written test and a skills test. Fees are typically $25 to $75.
  • Air brake (X) endorsement: Allows you to operate a commercial vehicle with air brakes. Requires a written test only. Fees are usually $10 to $30.
  • Tank vehicle (N) endorsement: Allows you to operate a commercial vehicle that carries liquid or gas in bulk. Requires a written test. Fees are typically $15 to $40.

Some endorsements can be combined. For example, you can hold both a hazmat and a passenger endorsement on the same CDL. However, each endorsement requires its own test and fee, and some endorsements have restrictions that prevent you from holding them together (your state's DMV will clarify this).

How to add an endorsement to your existing license

The process for adding an endorsement depends on whether you already hold a license and what type of endorsement you want. Here is the general sequence:

  1. Obtain the study manual for the endorsement from your state's DMV website or office.
  2. Study the manual and any supplementary materials (such as the CDL manual for a commercial endorsement).
  3. Schedule your written test at your local DMV office. Some states allow online scheduling; others require you to call or visit in person.
  4. Pass the written test. If you do not pass, you can usually retake it after a waiting period (often 1 to 7 days, depending on the state).
  5. If a skills test is required, schedule it at a DMV testing facility. You may need to bring your own vehicle or use one provided by the facility.
  6. Pass the skills test. If you do not pass, you can usually retake it after a waiting period.
  7. If a medical exam or background check is required, complete it before or after the tests, depending on your state's procedure.
  8. Pay the endorsement fee at the DMV office.
  9. Receive your updated license with the endorsement notation.

The timeline varies widely. A motorcycle endorsement can be added in a single visit if you pass both tests on the same day. A CDL can take several months because you must schedule the medical exam, the written tests, and the skills test separately, and some facilities have long wait times.

State-by-state differences in endorsement rules and fees

Endorsement requirements, fees, and procedures differ by state. For example, some states require a CDL medical exam to be renewed every two years; others require it every five years. Some states charge a single flat fee for a CDL; others charge per test. Some states waive the motorcycle skills test if you complete an MSF course; others do not.

The written test content also varies. While all states test on federal CDL standards (for commercial endorsements), the specific questions and passing score may differ. Some states offer the test in multiple languages; others offer it in English only.

Before you begin the process, visit your state's DMV website and look for the endorsement you want. The website should list the specific tests required, the fees, the study materials, and the scheduling process. If the information is unclear, call your local DMV office and ask to speak with someone who handles endorsements.

Common mistakes when pursuing an endorsement

One of the most common mistakes is not obtaining a medical certificate before scheduling a CDL test. Many people pass the written and skills tests, then discover they cannot get the medical certificate because of a health condition, and their test results expire before they can resolve the issue. Get the medical exam first, or at least confirm with a certified medical examiner that you will pass before you invest time in the written and skills tests.

Another mistake is not studying the correct manual. Some people study the regular driver's license manual when they should be studying the CDL manual or the motorcycle manual. The tests are specific to the endorsement, and the regular manual will not cover the material you need to know.

A third mistake is not understanding the difference between an endorsement and a license class. Some people think they can add a motorcycle endorsement to a commercial license and then drive a motorcycle commercially without a separate passenger or hazmat endorsement. Endorsements are specific; you must have the exact endorsement for the task you are performing.

Frequently Asked Questions

Can I get multiple endorsements at the same time?

Yes, you can hold multiple endorsements on a single license. However, you must pass the test for each endorsement separately and pay each fee. Some endorsements have restrictions that prevent them from being combined, so check your state's rules before scheduling multiple tests.

What happens if I fail the endorsement test?

You can retake the test after a waiting period, which is usually 1 to 7 days depending on the state. You will need to pay the test fee again. There is no limit on how many times you can retake the test, but each attempt costs money and takes time.

Do I need to renew my endorsement?

Most endorsements renew automatically when you renew your driver's license. However, some endorsements, such as hazmat, have their own renewal cycle and expiration date. Check your license to see the expiration date of each endorsement, and plan to renew before it expires.

Can I transfer an endorsement from another state?

No. If you move to a new state, you must obtain a new license in that state and pass the endorsement tests again. Some states may waive the written test if you show proof of a valid endorsement from another state, but you will still need to pass the skills test and pay the fee.

What is the difference between an endorsement and a restriction?

An endorsement allows you to do something (drive a motorcycle, haul hazmat). A restriction prevents you from doing something (such as driving at night or without corrective lenses). Restrictions are noted on your license separately from endorsements.
