Massachusetts issues five classes of driver’s license, and the one you need depends entirely on what you plan to drive. Class D covers everyday passenger vehicles. Class M covers motorcycles. Classes A, B, and C are commercial licenses, sorted by vehicle weight and what you’re hauling or carrying. Each class has its own age minimums, testing, and fees, and operating a vehicle with the wrong class on your license can bring fines, suspension, or criminal charges.
Class D: The Standard Passenger License
Class D is the license almost every Massachusetts driver holds. State regulations treat it as a residual category: it covers any vehicle that doesn’t fall into the commercial or motorcycle classes.1Mass.gov. 540 CMR 2.00 – Motor Vehicle Regulations In practical terms, that means passenger cars, SUVs, pickup trucks, and vans built to carry fewer than 16 people including the driver. A Class D also covers motorized bicycles and motorized scooters.2Legal Information Institute. 540 CMR 2.06 – Operating a Motor Vehicle
You can apply for a Class D learner’s permit at 16. Applicants under 18 need a parent, legal guardian, or other authorized person to sign the application. The permit exam is 25 multiple-choice questions on traffic laws, road signs, impaired driving, and the Junior Operator Law. You have 25 minutes and need 18 correct to pass.3Mass.gov.

Class M: Motorcycles
A Class D does not let you ride a motorcycle. Operating a motorcycle or motor-driven cycle in Massachusetts requires a separate Class M license.2Legal Information Institute. 540 CMR 2.06 – Operating a Motor Vehicle The minimum age is 16, parental consent applies for minors, and the skills test is done on a two-wheeled vehicle, separate from the Class D road test.
Every rider must wear a helmet that meets federal safety standards. Compliant helmets carry a “DOT” certification label on the outer rear surface showing they meet FMVSS No. 218 for impact protection, penetration resistance, and retention.4eCFR. 49 CFR 571.218 – Standard No. 218, Motorcycle Helmets Riding without a compliant helmet is a citable offense on its own.
Riding a motorcycle without a Class M license is a criminal matter. Unlicensed operation carries a fine of up to $500 on a first offense, and repeat violations bring steeper penalties and possible vehicle impoundment.5General Court of Massachusetts. Massachusetts General Laws Part I, Title XIV, Chapter 90, Section 20
Classes A, B, and C: Commercial Licenses
Massachusetts commercial driver licenses follow the federal classification under 49 CFR 383.91, split into three groups by vehicle weight and by passenger or cargo type.6eCFR. 49 CFR 383.91 – Commercial Motor Vehicle Groups State regulations mirror the federal definitions.1Mass.gov. 540 CMR 2.00 – Motor Vehicle Regulations
- Class A (Combination Vehicle): Any combination of vehicles with a gross combination weight rating of 26,001 pounds or more, where the towed unit is rated above 10,000 pounds. This is the license for tractor-trailers and most heavy hauling.
- Class B (Heavy Straight Vehicle): Any single vehicle with a GVWR of 26,001 pounds or more, or that vehicle towing a unit rated at 10,000 pounds or less. Large buses, dump trucks, and box trucks fall here.
- Class C (Small Vehicle): Any vehicle that does not meet the Class A or B thresholds but is designed to carry 16 or more people including the driver, or that requires hazardous materials placards.
Federal law sets the minimum age at 18 for operating a commercial vehicle within Massachusetts (intrastate) and 21 for crossing state lines (interstate).7Federal Register. Commercial Drivers Licenses – Pilot Program to Allow Drivers Under 21 to Operate Commercial Motor Vehicles in Interstate Commerce Driving a commercial vehicle on the wrong class of license can trigger an immediate out-of-service order and federal disqualification.
CDL Endorsements
Several specialized types of commercial driving require endorsements added to your CDL. Common ones are T (tank vehicle), P (passenger transport), S (school bus), and H (hazardous materials). Each endorsement has its own knowledge test, and some require additional skills testing.
The hazardous materials endorsement is the one that takes real planning. The TSA runs a background investigation on every driver seeking to obtain, renew, or transfer an H endorsement. You visit an application center to submit fingerprints and documentation, and TSA recommends starting at least 60 days before you need the endorsement because processing alone can take over 45 days. The security assessment fee is $85.25, and the endorsement must be renewed every five years.8Transportation Security Administration. HAZMAT Endorsement
Junior Operator Rules for Drivers Under 18
Drivers between 16½ and 18 who hold a Class D or M license are classified as Junior Operators, and the restrictions on them go well beyond anything adult drivers face.9Mass.gov. Junior Operator Violations
For the first six months of licensure, a Junior Operator cannot carry any passenger under 18 who is not an immediate family member, unless a licensed driver who is at least 21 and has at least one year of experience is seated beside them.10General Court of Massachusetts. Massachusetts General Laws Part I, Title XIV, Chapter 90, Section 8 Emancipated minors can request an exemption. Junior Operators also cannot drive between midnight and 5:00 a.m. unless accompanied by a licensed parent or legal guardian with at least one year of experience and no suspension or revocation on their record.11Mass.gov. Junior Operator License (JOL) Requirements
Penalties escalate quickly. A first passenger-restriction violation brings a 60-day suspension and a $100 reinstatement fee. A second brings a 180-day suspension, the same fee, and mandatory attendance at a Driver Attitudinal Retraining Course. A third brings a one-year suspension and forces you to start over with a new learner’s permit and road test. The nighttime curfew carries a similar structure, with the added consequence that even a first offense requires reapplying for a permit.9Mass.gov. Junior Operator Violations Any suspension during the six-month passenger-restriction window extends the restriction.
Standard License or REAL ID
Whatever class you apply for, you’ll also choose between a Standard license and a REAL ID. The driving privileges are identical. The difference is paperwork at the counter and what the card does at a federal checkpoint.
A REAL ID requires four categories of documentation: one document proving lawful presence in the United States (such as a U.S. passport or birth certificate), one document verifying your Social Security number (such as a Social Security card or W-2), and two documents proving your Massachusetts address (such as a utility bill, lease, or mortgage statement).12Mass.gov. REAL ID in Massachusetts Undocumented residents cannot obtain a REAL ID. Non-citizens with lawful status of at least 12 months can apply for a limited-term REAL ID tied to their authorized stay.
A Standard license has a lighter burden. Applicants who do not have a Social Security number can submit an affidavit in its place, which is not an option for REAL ID.13Mass.gov. Affidavit of No Social Security Number Standard licenses still require proof of identity and Massachusetts residency, but not proof of lawful presence.
Since May 7, 2025, federal agencies including TSA no longer accept Standard licenses for purposes like boarding a domestic flight or entering a federal building.14Transportation Security Administration. TSA Publishes Final Rule on REAL ID Enforcement Beginning May 7, 2025 A valid U.S. passport still works at the airport, so a Standard license isn’t a dead end if you have other federal ID. For most people who fly even occasionally, a REAL ID is the simpler long-term choice.
Fees and How to Apply
The licensing process involves three paid steps: a permit exam, a road test, and the license itself. For a Class D passenger license, the permit exam is $30, the road test is $35, and the license is $50. A CDL in Class A, B, or C is $75, with the same $30 permit and $35 road test fees. Adding a motorcycle endorsement costs $15.15Mass.gov. Massachusetts Registry of Motor Vehicles Fees
Start by completing the Driver’s License, Learner’s Permit, or ID Card Application (Form LIC100) from the RMV website.16Massachusetts Registry of Motor Vehicles. Drivers License, Learners Permit, or ID Card Application Schedule an appointment at an RMV Service Center, bring your paperwork and supporting documents, and a staff member will review everything and administer a vision screening. You then take the computerized permit exam on-site. Pass it and you walk out with a learner’s permit for supervised practice.3Mass.gov. Apply for a Passenger (Class D) Learner’s Permit
When you’re ready for the road test, schedule it at an RMV location. You need to bring a valid learner’s permit, a sponsor (a licensed driver 21 or older), and a vehicle in safe working order with valid registration and insurance. For a Class D test, the vehicle must have working brakes, mirrors, signals, seat belts, and proper tires.17Mass.gov. Passenger (Class D) Road Tests If you pass, your permit is stamped and acts as a temporary license until the permanent card arrives in the mail.
