An AC class license is for riding motorcycles and motor scooters with engines up to 125cc

An AC class license (sometimes called an A1 class in some states) is a motorcycle license that lets you ride smaller motorcycles and scooters legally. The engine size limit is usually 125 cubic centimeters (cc) or smaller, and the bike's power output is capped at around 11 kilowatts (about 15 horsepower). This class exists because smaller bikes are considered lower-risk for new or younger riders.

The AC class is different from a full motorcycle license (often called an A or unrestricted class), which lets you ride any motorcycle regardless of engine size. It's also different from a moped or scooter license in states that have separate categories — an AC class typically requires more training and testing than a basic moped permit, but covers a wider range of two-wheeled vehicles.

Not every state uses the term "AC class." Some call it A1, some call it a restricted motorcycle license, and some don't have a separate small-bike category at all. The rules depend on your state's Department of Motor Vehicles (DMV) or equivalent agency. Check your state's specific motorcycle license classes before you study for a test.

Key Takeaways

  • An AC class license covers motorcycles and scooters with engines of 125cc or smaller, making it the entry-level motorcycle license in most states that offer it.
  • You must be a certain age (usually 16 or 17, depending on your state) to get an AC class license, and you may need to complete a motorcycle safety course.
  • The written test covers motorcycle rules, hazard awareness, and safe riding practices; the riding test shows that you can control the bike in real-world conditions.
  • An AC class license does not let you ride larger motorcycles — if you want to upgrade later, you will need to pass tests for a higher class.
  • Some states let you get an AC class at a younger age than a full motorcycle license, which is why it is popular with teenagers learning to ride.

Age requirements and when you can get an AC class license

The minimum age for an AC class license varies by state, but it is usually between 16 and 17 years old. Some states let you get a learner's permit (sometimes called a motorcycle endorsement permit) at 15 or 16, which lets you ride under certain conditions — usually only during daylight, only with a licensed rider present, or only on certain roads — before you take the full test.

A few states have no separate AC class and instead offer only a full motorcycle license starting at 18. Others have an even lower age for a moped or motorized bicycle license, which is a different category. Your state's DMV website will list the exact age and any restrictions that come with a learner's permit in your state.

What you need to study and what the tests cover

Most states require you to pass a written test and a riding test to get an AC class license. The written test covers motorcycle-specific rules: how to brake and turn safely, what road signs mean for riders, how to check your bike before riding, and how to handle hazards like gravel, potholes, or other riders. You study from your state's motorcycle handbook, which is free and available online or at your DMV office.

The riding test takes place on a closed course or a quiet road, not in traffic. An examiner watches you start the bike, ride in a straight line, make turns, brake smoothly, and perform maneuvers like figure-eights or quick stops. The test shows that you can control a 125cc bike safely and understand how it handles. You use your own bike or a bike provided by the testing site — check your state's rules on which is allowed.

Many states let you skip the riding test if you complete an approved motorcycle safety course. These courses teach the same skills and usually take one or two days. They cost money (typically $100 to $300), but they save you the time of scheduling a separate riding test and often lower your insurance cost afterward.

Documents you need to bring to the DMV

To get an AC class license, you will need to bring proof of identity, proof of residency, and your Social Security number (or an Individual Taxpayer Identification Number if you don't have a Social Security number). Acceptable identity documents include a passport, birth certificate, or state ID. Proof of residency can be a utility bill, lease, or bank statement with your name and address.

If you are under 18, you may also need a parent or guardian's signature on an process form, depending on your state. Some states require a medical form signed by a doctor if you have certain health conditions that might affect your ability to ride safely. Check your state's DMV website for the exact list before you go.

How an AC class license differs from other motorcycle classes

The main difference between an AC class and a full (unrestricted) motorcycle license is engine size and power. An AC class is capped at 125cc and about 15 horsepower; a full license lets you ride any motorcycle, including large touring bikes or sport bikes with 1000cc engines and hundreds of horsepower. A full license usually requires you to be at least 18 years old and pass the same written and riding tests, but on a larger bike.

Some states let you upgrade from an AC class to a full license by passing another riding test on a larger bike — you don't have to retake the written test. Others require you to wait until you turn 18 or meet other conditions. A few states let you get a full license directly if you are old enough, without going through the AC class first.

An AC class is also different from a moped or motorized bicycle license, which covers smaller vehicles with engines under 50cc. Moped licenses usually require less training and testing, and sometimes no test at all. If you want to ride a 125cc scooter or motorcycle, you need at least an AC class license, not a moped license.

Insurance and registration for an AC class bike

Once you have an AC class license, you can legally ride a 125cc motorcycle or scooter. Before you ride on public roads, you must register the bike with your state's DMV and buy motorcycle insurance. Registration costs vary by state but are usually $50 to $150 per year. Insurance is required by law in every state and protects you if you cause an accident that injures someone or damages their property.

Motorcycle insurance for a small 125cc bike is often cheaper than car insurance because the bike is less expensive to repair and the risk of serious injury is lower than with a large motorcycle. Rates depend on your age, riding history, the bike's value, and the coverage limits you choose. Most insurers offer discounts if you complete a motorcycle safety course, which can save you money over time.

Upgrading to a larger motorcycle license later

If you start with an AC class license and later want to ride a larger motorcycle, you will need to get a higher class license. The process usually involves passing a new riding test on a bike that matches the class you want — for example, a test on a 500cc or larger bike if you want an unrestricted license. You do not have to retake the written test in most states, but some require you to wait a certain amount of time (like six months) between tests.

The riding test for a larger bike is harder because the bike is heavier, more powerful, and handles differently. Many riders take a motorcycle safety course before testing on a larger bike to build confidence and practice the new handling. Some courses offer bikes in different sizes, so you can train on the exact bike you plan to ride.

Frequently Asked Questions

Can I ride a 125cc scooter with an AC class license?

Yes. An AC class license covers motorcycles and scooters with engines up to 125cc. The license does not distinguish between a motorcycle and a scooter — it is the engine size that matters. A 125cc scooter is legal to ride with an AC class license.

What happens if I ride a bike larger than 125cc without the right license?

Riding a bike that exceeds your license class is illegal and counts as driving without a valid license for that vehicle. You can be fined, your bike can be impounded, and you may face criminal charges depending on your state. Your insurance will not cover an accident if you were riding illegally.

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

No, but most states let you skip the riding test if you complete an approved course. The course is optional, but it teaches skills you will need to ride safely and often reduces your insurance cost. Check your state's DMV website to see which courses are approved in your area.

Can I get an AC class license if I already have a car license?

Yes. A car license and a motorcycle license are separate. You must pass the motorcycle written and riding tests even if you have been driving a car for years. Motorcycle handling is very different from car handling, so the tests are designed to make sure you understand those differences.

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

If you take a safety course, you can finish in one or two days and have your license within a week or two. If you study on your own and schedule a separate riding test, it usually takes two to four weeks from the time you pass the written test to the time you pass the riding test and get your license. Processing time at the DMV varies by location.
