A Class DJ license lets you drive a motorcycle with an engine of 50cc or smaller, and in some states it also covers motorized bicycles and mopeds

The Class DJ is the smallest motorcycle license category. It is designed for riders of very low-powered two-wheeled vehicles. The exact vehicles covered depend on your state — some states use "DJ" as the official name, while others call it a "Moped" or "Motorized Bicycle" endorsement, but the rules are similar across most places.

You do not need a full motorcycle license to ride a 50cc scooter or moped. A Class DJ is faster and cheaper to obtain than a Class M motorcycle license, and the written test focuses on low-speed safety rather than highway riding. However, the restrictions are real: you cannot legally ride on interstate highways, and engine size limits are strictly enforced.

Key Takeaways

  • A Class DJ license covers motorcycles with engines of 50cc or smaller, and in many states also covers mopeds and motorized bicycles.
  • You must pass a written test about traffic laws and motorcycle safety, and in most states you must also pass a riding skills test or complete a safety course.
  • Riders with a Class DJ license cannot use interstate highways and must follow speed restrictions that vary by state, usually between 30 and 40 mph.
  • The minimum age to obtain a Class DJ is typically 14 or 15, though some states allow younger riders with parental consent.
  • Insurance requirements and helmet laws for Class DJ riders vary by state, so you must check your state's specific rules before riding.

What vehicles you can legally ride with a Class DJ

A Class DJ license covers any motorcycle with an engine displacement of 50cc or smaller. This includes most scooters, mopeds, and small-displacement motorcycles sold at dealerships. The 50cc limit is measured in cubic centimeters of engine volume — if the manufacturer's specification exceeds 50cc, you cannot legally ride it on a Class DJ license alone.

Many states also include motorized bicycles and mopeds under the Class DJ category, even if they have pedals. The rule depends on whether the vehicle has pedals and how much power the motor produces. Some states define a moped as a vehicle with pedals and an engine under 50cc, while others use engine size alone. Check your state's motor vehicle handbook to see exactly what counts in your area.

You cannot ride any motorcycle larger than 50cc on a Class DJ license. Attempting to do so is illegal and can result in a citation, even if you have a full motorcycle license for other purposes. Insurance will not cover you if you are riding an oversized vehicle on the wrong license class.

Age requirements and how to obtain a Class DJ license

The minimum age to obtain a Class DJ license is 14 or 15 in most states, though a few states allow riders as young as 12 or 13 with parental consent. Some states issue a "learner's permit" first, which requires you to ride with an adult or during daylight hours only, before you can take the full riding test. Check your state's motor vehicle department website for the exact age rule in your location.

To obtain a Class DJ license, you must pass a written test covering traffic laws, road signs, and motorcycle-specific safety rules. The test is usually shorter and less detailed than the test for a full motorcycle license. Many states also require you to pass a riding skills test on an actual motorcycle, or you can satisfy this requirement by completing a state-approved motorcycle safety course instead.

The written test is offered at your local motor vehicle office and costs between $10 and $30 depending on your state. If you choose to take the riding skills test instead of a safety course, you must bring your own motorcycle or scooter and demonstrate basic control, stopping, and turning. Most riders find it easier to take a safety course, which typically costs $100 to $200 and takes one or two days to complete.

Restrictions that explore to Class DJ riders

Class DJ riders cannot use interstate highways or limited-access expressways. You must use local roads and state highways only. This restriction exists because 50cc motorcycles are not powerful enough to safely merge with high-speed traffic or maintain highway speeds in bad weather.

Most states impose a speed limit on Class DJ riders, usually between 30 and 40 mph, though the exact limit varies. Some states do not set a separate speed limit and instead require you to follow the posted speed limit for the road you are on, as long as you do not exceed your vehicle's safe operating speed. Check your state's motorcycle handbook for the specific rule.

Many states require Class DJ riders to wear a helmet at all times, while a few states allow riders over a certain age to ride without one if they have insurance. Some states also require eye protection and protective clothing. These rules are separate from the license class itself and explore based on your age and state law.

Insurance and registration for a Class DJ motorcycle

Insurance requirements for Class DJ riders vary significantly by state. Some states require liability insurance for any motorized vehicle, including 50cc scooters. Other states do not require insurance for vehicles under a certain engine size or speed capability. A few states require only that you carry proof of financial responsibility, which can be satisfied through insurance or a bond.

You must register your 50cc motorcycle or scooter with your state's motor vehicle department, even though it is a small vehicle. Registration typically costs $20 to $50 per year and requires proof of ownership and your Class DJ license. Some states offer a reduced registration fee for vehicles under 50cc.

Contact your state's motor vehicle department or a local insurance agent to find out the exact insurance and registration rules for your area. The cost of insurance for a 50cc scooter is usually low — often $100 to $300 per year — because the vehicles are slow and less likely to cause serious accidents.

How a Class DJ license differs from a full motorcycle license

A full motorcycle license (usually called Class M or Class A) allows you to ride any motorcycle, regardless of engine size. It requires a more difficult written test, a more challenging riding skills test, and in many states a longer waiting period between obtaining a learner's permit and taking the riding test. The minimum age for a full motorcycle license is usually 16 or 18, depending on your state.

A Class DJ license is simpler and faster to obtain because the test focuses only on low-speed safety and basic control. You can get a Class DJ license at a younger age, and the written test is shorter. However, you are limited to 50cc vehicles and cannot ride on highways, which makes a Class DJ license useful mainly for short trips around town or for young riders who are not yet ready for a full motorcycle license.

Some riders obtain a Class DJ license first, gain experience, and then upgrade to a full motorcycle license later. Other riders keep a Class DJ license indefinitely if they only ride small scooters for commuting. The choice depends on what vehicles you want to ride and where you plan to ride them.

Frequently Asked Questions

Can I upgrade from a Class DJ license to a full motorcycle license?

Yes. You can take the written and riding tests for a full motorcycle license at any time, even if you already have a Class DJ license. You do not need to wait or meet any additional requirements — your state will straightforward issue you a full motorcycle license in addition to or in place of your Class DJ license. The cost and testing process are the same as if you were obtaining a motorcycle license for the first time.

What happens if I ride a motorcycle larger than 50cc on a Class DJ license?

You will be breaking the law and can receive a citation for operating a vehicle without the proper license class. The fine varies by state but typically ranges from $100 to $500. Your insurance will not cover any accident or damage that occurs while you are riding an oversized vehicle on the wrong license class, which means you would be personally liable for all costs.

Do I need to take a safety course, or can I just pass the riding test?

Most states allow you to choose either option. You can take the state-administered riding skills test at your motor vehicle office, or you can complete a state-approved motorcycle safety course instead. The safety course usually takes one or two days and costs $100 to $200, while the riding test is free or low-cost but requires you to bring your own motorcycle. Many riders choose the safety course because it is easier to pass and teaches more practical skills.

Can I ride a Class DJ motorcycle if I am under the minimum age with a learner's permit?

Yes, but with restrictions. Most states allow learner's permit holders to ride during daylight hours only, and some require an adult to ride with them or follow in another vehicle. The exact restrictions depend on your state and your age. Check your state's motor vehicle handbook or ask at your local motor vehicle office for the specific rules that explore to you.

Do I need a helmet if I have a Class DJ license?

Most states require all motorcycle riders, including Class DJ riders, to wear a helmet at all times. A few states allow riders over age 18 or 21 to ride without a helmet if they have insurance or have completed a safety course. Check your state's helmet law, because riding without a helmet when it is required can result in a citation and fine, even if you have a valid license.
