What an AC Class License Is and Who Needs One

An AC class license is a motorcycle endorsement that permits you to ride automatic-transmission motorcycles and scooters. The "AC" designation appears on your license card and means you are restricted to bikes with automatic clutches — you cannot legally operate manual-transmission motorcycles even if you know how to ride them.

Most states do not issue a separate AC class license. Instead, they issue a full motorcycle endorsement (usually called Class M or Class A) that covers both automatic and manual bikes. A few states — primarily Australia and some European countries — use the AC classification as a restricted category for riders who have not passed the manual transmission test or who are under a certain age.

If you are in the United States, check your state's DMV website first. You almost certainly need a standard motorcycle endorsement, not an AC class. If you are outside the US or your state does use AC classification, the process below covers the typical requirements.

Key Takeaways

  • Most US states do not recognize AC class licenses; they issue full motorcycle endorsements instead, which cover both automatic and manual bikes.
  • If your state does use AC classification, you will need to pass a written motorcycle knowledge test, a riding skills test on an automatic bike, and a vision and medical screening.
  • Age requirements vary by state but typically range from 16 to 18 years old for a motorcycle endorsement.
  • The riding test is usually conducted on your own automatic motorcycle or a state-provided bike, and you must demonstrate basic control, stopping, and turning.
  • Fees for motorcycle endorsements or AC class licenses range widely by state and typically cost between $15 and $50 for the endorsement itself.

Age and Residency Requirements

Age requirements for a motorcycle endorsement or AC class license depend on your state. Most states allow riders as young as 16 to obtain a motorcycle endorsement, though some require you to be 18. A few states offer a learner's permit for younger riders (sometimes called a motorcycle instruction permit) that lets you practice under supervision before taking the full test.

You must be a resident of the state where you explore. Residency is typically proven with a utility bill, lease, or mortgage statement dated within the last 60 days, or by holding a valid driver's license from that state. If you are not yet a resident, you will need to obtain a state ID or driver's license first.

Some states allow non-residents to test for a motorcycle endorsement if they hold a valid out-of-state driver's license, but the rules vary. Contact your state DMV before traveling to test.

Written Knowledge Test Requirements

You will need to pass a motorcycle knowledge test that covers traffic laws, road signs, hazard recognition, and motorcycle-specific skills like braking and turning. The test is usually 25 to 50 questions, and you must score at least 80 percent to pass. Most states allow you to retake the test the same day if you fail, though some require a waiting period.

Study materials are free and available on your state DMV website. Many states publish the exact question bank or a study guide. Some offer online practice tests. You do not need to pay for a third-party study app, though they exist.

The test is administered at your local DMV office or testing center. You take it on a computer or on paper, depending on your state. Bring your learner's permit or ID and any required documents listed on the DMV website.

Riding Skills Test and Bike Requirements

After passing the written test, you must pass a riding skills test on an automatic-transmission motorcycle. The test is usually 10 to 15 minutes long and takes place in a closed course or parking lot. You will be asked to demonstrate basic control: starting, stopping, turning, swerving, and riding in a straight line.

You can bring your own automatic motorcycle or use one provided by the state. If you use your own bike, it must be registered, insured, and in safe working condition. The examiner will do a quick safety check (brakes, lights, tires) before the test begins. If your bike fails, you cannot test that day.

Some states offer Motorcycle Safety Foundation (MSF) courses that waive the riding test if you pass. These courses are taught by certified instructors and take one to three days. You pay a course fee (typically $150 to $300) but skip the DMV riding test. This route is often faster and less stressful than the DMV test, especially if you are new to riding.

Vision and Medical Screening

You must pass a vision test showing you can see at least 20/40 in each eye (with or without corrective lenses). If you wear glasses or contacts, bring them to the DMV. You will also be asked about your medical history — specifically whether you have conditions that affect your ability to ride safely, such as seizure disorders, severe hearing loss, or loss of limb function.

Most medical conditions do not automatically disqualify you. The DMV will ask follow-up questions and may require a letter from your doctor confirming you can operate a motorcycle safely. If you have a condition you are unsure about, call your state DMV before explore.

Documents to Bring and Fees

Bring the following to your DMV appointment:

  • A valid state ID or driver's license
  • Proof of residency (utility bill, lease, or mortgage statement dated within 60 days)
  • Your Social Security number or an ITIN
  • Proof of motorcycle insurance (if you are using your own bike for the riding test)
  • Your motorcycle registration (if you are using your own bike)
  • Corrective lenses if you wear them

Fees vary by state. A motorcycle endorsement or AC class license typically costs between $15 and $50. Some states charge separately for the written test, the riding test, and the license itself. A few states charge nothing. Check your state DMV website for the exact breakdown.

If you take an MSF course instead of the DMV riding test, you will pay the course fee (usually $150 to $300) but may save the DMV riding test fee. The course fee is not refundable if you do not complete it.

State-by-State Differences in AC Class Licensing

The United States does not have a uniform AC class license system. Most states issue a single motorcycle endorsement (Class M, Class A, or Class 1) that covers all motorcycles, regardless of transmission type. You do not need a separate test for automatic bikes.

If you are in a state that does recognize AC classification, the process above applies. If you are outside the US, check your country's or region's licensing authority. Australia, for example, uses the AC class for riders under 24 or those who have not passed a manual transmission test. The UK uses the AM class for automatic scooters under 50cc.

If you are unsure whether your state uses AC classification, search "[your state] motorcycle endorsement" on the DMV website or call the motorcycle licensing unit directly. They can tell you in one call whether you need an AC class or a standard motorcycle endorsement.

Frequently Asked Questions

Can I ride a manual motorcycle with an AC class license?

No. An AC class license restricts you to automatic-transmission bikes only. If you want to ride a manual motorcycle, you must pass the riding test on a manual bike or take an MSF course that covers manual transmission. You can then upgrade to a full motorcycle endorsement.

What happens if I fail the riding test?

Most states let you retake the test the same day or within a few days at no extra charge. Some charge a small retest fee ($5 to $15). You do not have to retake the written test. If you fail multiple times, some states require you to wait 30 days before trying again or to take a motorcycle safety course.

Do I need a motorcycle safety course to get an AC class license?

No, but taking one can make the process faster. An MSF or state-approved course waives the DMV riding test in most states. If you are nervous about the riding test or new to motorcycles, a course is worth the cost and time.

Can I get an AC class license if I already have a driver's license?

Yes. A motorcycle endorsement is added to your existing driver's license. You do not need a separate license card in most states — the endorsement appears on your current license or on a separate document you carry with it.

How long does it take to get an AC class license?

If you pass the written and riding tests on the same day, you can receive your endorsement the same day or within a few days. If you take an MSF course first, add one to three days for the course. If you fail a test and need to retake it, add a few days to a few weeks depending on your state's retesting schedule.
