What an AC class license covers and who needs one
An AC class license is a motorcycle endorsement that lets you ride automatic transmission motorcycles and scooters. The "A" stands for motorcycle, and the "C" specifies automatic transmission only — you cannot ride manual clutch bikes with this class alone. If you want to ride both automatic and manual motorcycles, you need an A class license instead.
You need an AC class license if you own or plan to ride any automatic motorcycle or scooter, regardless of engine size. Some states have no engine displacement limit for AC class; others cap it at 125cc or 150cc. Check your state's motor vehicle handbook or website to confirm the specific rules where you live, because these limits vary.
The AC class is often the fastest route to motorcycle riding if you prefer automatic transmission bikes. The written test and riding test are usually shorter than the full A class process, and you do not need to demonstrate manual clutch control.
Key Takeaways
- You must be at least 16 or 17 years old (depending on your state) and hold a valid driver's license or learner's permit before you can test for an AC class endorsement.
- The written test covers motorcycle safety, road signs, and traffic laws specific to riding; study materials are free from your state's motor vehicle department.
- The riding test happens on an automatic motorcycle provided by the testing site or your own bike, and you must demonstrate basic control, stopping, and turning.
- Most states let you take the written test and riding test on the same day, though some require a waiting period between them.
- After you pass both tests, you pay a fee (usually $15 to $50) and receive your AC class endorsement added to your existing driver's license.
Age requirements and what license you need to start
You must be at least 16 years old in most states to get an AC class license, though a few states require 17 or 18. Check your state's motor vehicle handbook for the exact minimum age, because it varies.
You also need either a valid driver's license or a learner's permit before you can test for the AC endorsement. You cannot get an AC class as your first license — it is always added to an existing driver's license. If you do not yet have a driver's license, you must get one first through the standard written and driving test process.
Some states let you hold a learner's permit and test for the AC class at the same time. Others require you to have a full driver's license already. Contact your state's motor vehicle department or check their website to confirm which applies to you.
The written test: what to study and where to find materials
The AC class written test covers motorcycle-specific safety and traffic laws. You will answer questions about how to brake on a motorcycle, what to do if your front tire blows out, how to lean into turns, and how to spot hazards on the road. The test also includes standard traffic signs and road markings.
Study materials are free. Your state's motor vehicle department publishes a motorcycle handbook online and in print at any DMV office. The handbook contains all the information the test covers. Some states also offer free practice tests on their website or through their mobile app — take these multiple times until you score 80 percent or higher consistently.
The written test usually has 25 to 50 questions and you must score at least 80 percent to pass. You take it at a DMV office or testing center on a computer or paper form. Most states let you retake it the same day if you fail, though a few require you to wait a week.
The riding test: what the examiner watches for
The riding test happens on an automatic motorcycle, either one you bring or one the testing site provides. The examiner watches you perform basic riding skills: starting the bike, riding in a straight line, stopping smoothly, turning at different speeds, and swerving to avoid an obstacle. The test usually lasts 10 to 15 minutes and takes place in a closed course or parking lot, not on public roads.
The examiner is looking for smooth throttle control, proper braking, and the ability to keep the bike upright and stable. You must demonstrate that you can handle the bike safely at low and moderate speeds. Common reasons people fail are jerky acceleration, braking too hard, leaning too far, or dropping the bike.
Wear a helmet, long pants, closed-toe shoes, and a long-sleeved shirt or jacket — most testing sites require this safety gear and will not let you test without it. Arrive early so you have time to get comfortable with the bike before the test starts.
Timing: how long the whole process takes
The written test and riding test can usually happen on the same day. You take the written test first, and if you pass, you move directly to the riding test a few minutes later. Some states require a waiting period of one to seven days between the two tests — check your state's rules before you schedule.
Preparation typically takes one to four weeks if you study the handbook regularly and practice on an automatic motorcycle beforehand. If you already ride automatic bikes, you may feel ready in a week or two. If you have never ridden before, give yourself more time to build muscle memory and confidence.
After you pass both tests, the DMV processes your endorsement and adds it to your driver's license. This usually takes one to two weeks. You receive your updated license by mail or can pick it up at the DMV office the same day, depending on your state.
The fee and what happens after you pass
The fee for an AC class endorsement ranges from $15 to $50 depending on your state. Some states charge a single flat fee; others charge separately for the written test, riding test, and license update. Ask the DMV what the total cost will be before you schedule your tests.
Once you pass both tests and pay the fee, the AC class endorsement is added to your existing driver's license. You do not receive a separate motorcycle license — it appears as a code or notation on your regular driver's license. Your license will show something like "Endorsement: AC" or "Motorcycle - Automatic" depending on how your state formats it.
You can then legally ride any automatic motorcycle or scooter in your state. If you later want to upgrade to an A class license (to ride manual transmission bikes), you can test for that endorsement separately — you do not have to start over from scratch.
Preparing for the riding test if you have never ridden before
If you have never ridden a motorcycle, spend at least two to four weeks practicing on an automatic bike before you test. Borrow a friend's automatic scooter or motorcycle, or rent one from a local shop. Practice in a parking lot or quiet street until you feel confident with starting, stopping, turning, and basic speed control.
Some states offer motorcycle safety courses that include classroom instruction and hands-on riding practice. These courses often waive the riding test — if you pass the course, you can get your AC endorsement without taking the DMV riding test. The course usually costs $100 to $300 and takes one to two days. Check whether your state recognizes these courses before you enroll.
Focus on smooth, gradual movements rather than jerky ones. Practice emergency stops, gentle turns, and riding in straight lines. The examiner is not testing speed or tricks — just basic control and safety awareness.
Frequently Asked Questions
Can I take the riding test on my own bike or do I have to use the DMV's bike?
Most states let you use your own automatic motorcycle if it is registered and insured. Some testing sites provide bikes for a small fee if you do not have one. Call your local DMV to ask what bikes are available and whether you can bring your own.
What if I fail the written test or riding test?
You can retake either test. Most states let you retake the written test the same day or within a few days. The riding test usually requires you to wait a few days or a week before retesting. You pay the test fee again each time you retake it.
Do I need to take a motorcycle safety course to get an AC class license?
No, a safety course is not required in most states. However, some states waive the riding test if you pass an approved safety course, which can save you time. Check your state's motor vehicle website to see if this option is available where you live.
Can I ride a manual transmission motorcycle with an AC class license?
No. An AC class license covers automatic transmission only. If you want to ride manual clutch motorcycles, you must test for an A class endorsement instead, which requires demonstrating manual clutch control on the riding test.
How long is an AC class endorsement valid?
An AC class endorsement is valid as long as your driver's license is valid. When your driver's license expires and you renew it, the AC endorsement renews automatically — you do not have to retake the tests.
