The M endorsement lets you drive a motorcycle on a commercial license
An M endorsement is an add-on to your commercial driver's license (CDL) that permits you to operate motorcycles for work. Without it, your CDL does not cover motorcycles — even if you hold a regular motorcycle license for personal use. The M endorsement is separate from your standard CDL classes (A, B, or C) and requires its own knowledge test and, in most states, a skills test on an actual motorcycle.
You might need this endorsement if your job involves riding a motorcycle commercially — for example, as a motorcycle courier, police officer, or delivery driver. The requirements and testing process vary by state, but all states that offer the M endorsement require you to pass a written exam covering motorcycle-specific rules and hazards.
Key Takeaways
- The M endorsement is added to a CDL and allows you to operate motorcycles for commercial purposes.
- You must pass a written test about motorcycle operation and safety; most states also require a riding skills test on a motorcycle.
- Holding a personal motorcycle license does not automatically give you the M endorsement on your CDL.
- Not all states offer the M endorsement, so check your state's CDL handbook to see if it is available where you live.
When you need the M endorsement versus a regular motorcycle license
A regular motorcycle license (often called an M-class or motorcycle endorsement on a standard driver's license) covers you for personal motorcycle use. A CDL with an M endorsement is required only when you are riding a motorcycle as part of your job — that is, for commercial purposes.
The distinction matters because employers and law enforcement treat commercial and personal riding differently. If you are a motorcycle courier or ride for delivery, you need the M endorsement on your CDL. If you ride a motorcycle to work but do not use it for work itself, your regular motorcycle license is sufficient. Some states do not distinguish between the two and may not offer a separate M endorsement on the CDL; in those cases, check your state's CDL manual to understand what motorcycle operation is permitted under your license class.
What the M endorsement written test covers
The written test for the M endorsement focuses on motorcycle-specific knowledge that differs from four-wheel vehicle operation. You will be tested on topics like how motorcycles handle in different weather, how to brake and accelerate safely on two wheels, how to position yourself in a lane, and how to spot hazards that affect motorcycles differently than cars.
The test also covers motorcycle maintenance basics — tire pressure, chain tension, and brake fluid levels — because a small mechanical problem on a motorcycle is more dangerous than on a car. You will study your state's CDL handbook, which has a section dedicated to motorcycle operation. Most states allow you to take this test at the same location where you test for your CDL, often at your local DMV or testing center.
The motorcycle skills test and what examiners watch for
Most states require you to demonstrate your riding ability on an actual motorcycle during a skills test. You will ride a course set up by the testing authority — usually in a parking lot or closed area — while an examiner watches for safe handling, control, and awareness. The examiner is looking for smooth acceleration and braking, proper turning technique, and your ability to maintain balance and lane position.
You must provide your own motorcycle for the test in most states, though a few allow you to use a state-provided bike. The motorcycle must be street-legal and registered, and you must wear a helmet and protective gear as required by your state's laws. If you do not own a motorcycle, you may be able to rent one from a motorcycle training school, many of which offer bikes specifically for CDL testing.
How to prepare for the M endorsement test
Start by reading the motorcycle section of your state's CDL handbook — this is the primary source for the written test. Many states also offer study guides or practice tests online through their DMV website. Take these practice tests seriously; they closely mirror the real exam.
For the skills test, practice on a motorcycle in a safe, controlled environment before your test date. If you are not already an experienced rider, consider taking a motorcycle safety course. Many states recognize completion of a Motorcycle Safety Foundation (MSF) course or similar state-approved training and may waive or reduce the skills test requirement. Check your state's CDL handbook to see if this option is available to you. Even if it is not required, the training will make you a safer rider and more likely to pass the test on your first attempt.
States that offer the M endorsement
Not every state includes an M endorsement on its CDL. Some states treat motorcycle operation under different rules or do not permit commercial motorcycle operation at all. Before you begin studying or scheduling a test, confirm that your state offers the M endorsement by checking your state's CDL handbook or contacting your local DMV.
If your state does not offer an M endorsement but you need to ride a motorcycle for work, ask your state's CDL program what rules explore. Some states may allow motorcycle operation under certain conditions without a separate endorsement, while others may require you to hold both a CDL and a separate motorcycle license. The rules are specific to each state, so direct contact with your DMV is the most reliable way to get an answer.
The cost and timeline for adding the M endorsement
The cost of the M endorsement varies by state. Most states charge a testing fee that ranges from $10 to $50 for the written exam, and an additional fee for the skills test if your state requires one. Some states bundle these into a single endorsement fee. Check your state's DMV website or call your local office to learn the exact cost.
The timeline depends on how quickly you can schedule your tests. The written test can often be taken within a few days of explore, but the skills test may have a longer wait depending on how many examiners are available in your area. Plan for at least two to four weeks from start to finish, though this varies widely. Once you pass both tests, the endorsement is usually added to your CDL within a few business days.
Frequently Asked Questions
Do I need an M endorsement if I already have a motorcycle license?
A personal motorcycle license and a CDL with an M endorsement are separate. You need the M endorsement on your CDL only if you ride a motorcycle for commercial purposes — as part of your job. A personal motorcycle license does not automatically add the M endorsement to your CDL, even though you may be may have access to to ride. You must test for the endorsement separately.
Can I take the M endorsement test without owning a motorcycle?
Most states require you to provide your own motorcycle for the skills test, but you do not have to own one. You can rent a motorcycle from a rental company or motorcycle training school. Some training schools offer bikes specifically for CDL testing. A few states allow you to use a state-provided motorcycle, so check your state's CDL handbook to see if this option is available.
What happens if I fail the M endorsement skills test?
If you fail the skills test, you can retake it. The number of retakes allowed and the waiting period between attempts vary by state. Most states allow you to retake the test within a few days or weeks. You will likely pay the test fee again. Consider additional practice or training before your next attempt.
Can I get the M endorsement waived if I complete a motorcycle safety course?
Some states waive the skills test if you complete an approved motorcycle safety course, such as one offered by the Motorcycle Safety Foundation (MSF). A few states may waive both the written and skills tests. Check your state's CDL handbook or contact your DMV to see if this option is available where you live.
Does the M endorsement expire or need to be renewed?
The M endorsement is part of your CDL and renews on the same schedule as your CDL. When you renew your CDL, the M endorsement renews with it. You typically do not need to retake the M endorsement test during renewal unless your state has specific rules about endorsement renewal — check your state's CDL handbook for details.
