What Are the Different Driver’s License Types and Classes?

Driver’s license types and classes in the United States fall into three broad groups: standard licenses for personal vehicles, commercial driver’s licenses (CDLs) in Classes A, B, and C for heavy or specialized vehicles, and motorcycle licenses or endorsements. Which one you need depends mostly on the weight of the vehicle, what or whom you’re carrying, and whether you’re driving for work. Federal regulations set the framework for commercial classes, while each state controls its own standard license system, age rules, and naming conventions.

Standard Licenses for Personal Vehicles

The license most people carry covers passenger cars, pickups, SUVs, and vans for personal use. States label it differently. Class D, Class C, and Class E are all common, but the scope is roughly the same everywhere: any single non-commercial vehicle with a gross vehicle weight rating (GVWR) under 26,001 pounds, towing a trailer rated at no more than 10,000 pounds GVWR. That covers virtually every personal car, minivan, light truck, and mid-size recreational vehicle on the road.

Fees vary widely by state and by how long the license is valid. Expect somewhere between $9 and $89 for an initial issue or renewal. Multi-year licenses at the higher end often work out cheaper per year than shorter ones.

Standard licenses can also carry restrictions, such as corrective lenses, daylight-only driving, or automatic transmission only. Those codes are not federally standardized and vary by state.

Graduated Licensing for New Drivers

Every state phases teenagers into full driving privileges through a graduated driver licensing (GDL) system. New drivers gain experience under controlled conditions before they’re allowed to drive alone at night or with other teens in the car. The structure has three stages in nearly every state.

  • Learner’s permit. The teen drives only with a licensed adult in the passenger seat. Most states require passing a written knowledge test and logging a set number of supervised practice hours, often 30 to 50, before advancing. The minimum age ranges from 14 to 16.
  • Intermediate (provisional) license. The teen can drive alone but faces restrictions, usually a nighttime curfew and limits on teenage passengers. A behind-the-wheel road test is required to reach this stage, and the minimum age is generally 16 or older.
  • Full license. GDL restrictions lift once the driver reaches 18 in most states, provided they’ve stayed crash- and conviction-free during the intermediate stage.

Specifics differ: how many practice hours count, what counts as “nighttime,” how many passengers are allowed. Violating intermediate-stage restrictions can delay graduation to the next level.

Commercial Driver’s License Classes

Driving large trucks, buses, or vehicles carrying hazardous cargo for work requires a CDL. Federal law divides commercial motor vehicles into three groups, and every state follows the same weight-based classifications.1eCFR. 49 CFR 383.91 – Commercial Motor Vehicle Groups

Class A CDL

Class A covers combination vehicles — a power unit pulling one or more trailers — with a gross combination weight rating of 26,001 pounds or more, where the towed unit itself exceeds 10,000 pounds GVWR. This is the license for tractor-trailers, flatbeds hauling heavy equipment, and large livestock rigs.

Class B CDL

Class B is for any single vehicle with a GVWR of 26,001 pounds or more, or that same heavy vehicle towing a lighter trailer rated at 10,000 pounds or less. City buses, large dump trucks, concrete mixers, and box trucks fall here. A Class B holder can also operate any vehicle that falls into the Class C CDL category.

Class C CDL

Class C applies to vehicles that don’t meet the Class A or B weight thresholds but are regulated because of what, or whom, they carry. The two triggers are transporting 16 or more passengers (including the driver) and hauling hazardous materials in quantities that require placards. Small shuttle buses and certain hazmat delivery vehicles are typical examples.

What Getting a CDL Requires

A CDL involves more than a tougher driving test. Federal rules add age minimums, mandatory training, and ongoing medical screening.

Age

Federal law requires you to be at least 21 to drive a commercial motor vehicle across state lines.2Federal Motor Carrier Safety Administration. FAQs Most states issue CDLs to drivers as young as 18 for intrastate-only routes, meaning the vehicle never crosses a state border. FMCSA also runs a Safe Driver Apprenticeship Pilot Program that allows qualified drivers aged 18 to 20 to operate in interstate commerce under structured supervision.3Federal Motor Carrier Safety Administration. FMCSA Safe Driver Apprenticeship Pilot Program

Entry-Level Driver Training

Before taking CDL skills tests, you must complete Entry-Level Driver Training (ELDT) through a provider listed on FMCSA’s Training Provider Registry. ELDT applies to first-time Class A or Class B applicants, drivers upgrading from Class B to Class A, and anyone adding a school bus, passenger, or hazardous materials endorsement. Drivers who qualify for a skills-test exception under federal rules are exempt.4Federal Motor Carrier Safety Administration. Entry-Level Driver Training (ELDT)

Medical Certification

CDL holders in non-excepted interstate commerce must be medically certified as physically qualified. That means passing a physical examination by a medical examiner listed in the FMCSA’s National Registry. The resulting medical examiner’s certificate, commonly called a DOT medical card, must be kept current and submitted to your state licensing agency. As of June 2025, CDL and commercial learner’s permit holders no longer need to carry the physical card while driving, since the information is now stored electronically.5eCFR. 49 CFR 391.41 – Physical Qualifications for Drivers

Drivers who operate only within their home state follow that state’s own medical rules, which may be less stringent. FMCSA requires every CDL holder to self-certify into one of four categories — non-excepted interstate, excepted interstate, non-excepted intrastate, or excepted intrastate — so the state knows which medical requirements apply.6Federal Motor Carrier Safety Administration. How Do I Determine Which of the 4 Categories of Commercial Motor Vehicle Operation I Should Self-Certify To

CDL Endorsements

Endorsements are add-ons that authorize you to operate specific vehicle types or haul certain cargo. Each requires passing an additional knowledge test, and some require a skills test as well. Federal regulation assigns a standard letter code to each one.7eCFR. 49 CFR 383.153 – Information on the CLP and CDL Documents and Records

  • H — Hazardous materials, required for any vehicle hauling hazmat in placardable quantities.
  • N — Tank vehicle, required for operating a tank vehicle as defined by federal rules.
  • P — Passenger, required to carry 16 or more people including the driver.
  • S — School bus, required for any school bus route.
  • T — Double or triple trailers, required to pull two or three trailers at once.
  • X — Hazmat and tank combined in a single code.

The hazmat endorsement carries extra scrutiny. TSA runs a security threat assessment on every applicant, including fingerprinting and a background check. The current fee is $85.25, and TSA recommends starting the process at least 60 days before you need the endorsement.8Transportation Security Administration. HAZMAT Endorsement

CDL Restrictions

If you pass your CDL skills test in a vehicle that lacks certain features, a restriction code gets printed on your license limiting what you can drive. These aren’t penalties; they reflect what you demonstrated during the test. The federally standardized codes are:7eCFR. 49 CFR 383.153 – Information on the CLP and CDL Documents and Records

  • L — No air brake equipped CMV. You tested in a vehicle without air brakes or failed the air brake knowledge test.
  • Z — No full air brake equipped CMV. You tested in a vehicle with air-over-hydraulic brakes rather than full air brakes.
  • E — No manual transmission CMV. You tested in an automatic.
  • O — No tractor-trailer CMV. Your Class A test used a pintle hook or other non-fifth-wheel connection.
  • K — Intrastate only. You’re limited to driving within your home state, typically because you’re under 21 or don’t meet interstate medical requirements.
  • V — Medical variance. You hold a medical exemption from one or more standard physical qualification requirements.

Removing a restriction generally means retesting in the appropriate vehicle. Testing in an automatic and later wanting to drive a manual requires a new skills test in a manual-equipped truck.9eCFR. 49 CFR 383.95 – Restrictions

Who Doesn’t Need a CDL

Not everyone driving a heavy vehicle needs a CDL. Federal law creates several carve-outs.10eCFR. 49 CFR 383.3 – Applicability

  • Active-duty military personnel, including reservists, National Guard members on active duty, and active Coast Guard, when operating vehicles for military purposes. This exemption is mandatory in every state.
  • Farmers driving farm vehicles to transport agricultural products or supplies within 150 miles of the farm, as long as the vehicle isn’t used for a for-hire carrier.
  • Firefighters, ambulance operators, and others driving emergency vehicles equipped with lights and sirens.
  • Local government employees clearing snow and ice during emergencies.

The farmer, emergency, and snow-removal exemptions are optional. Each state decides whether to offer them and under what conditions.

Motorcycle Licenses

Riding a motorcycle on public roads requires either a separate motorcycle license or a motorcycle endorsement added to your existing driver’s license. The licensing threshold in most states is an engine displacement above 50 cubic centimeters. Vehicles at or below that cutoff, typically called mopeds, usually require only a standard license or a lower-tier permit, though the exact rules and speed limits vary.

Earning a motorcycle license or endorsement involves a written knowledge test focused on motorcycle-specific safety and a practical riding skills test. Many states let you skip the riding test if you complete an approved safety course, which is worth considering since the course doubles as actual training. If you take the skills test on a three-wheeled motorcycle, expect a restriction limiting you to three-wheeled vehicles only.

Scooters sit in a middle ground that trips people up. A scooter with an engine over 50cc is treated as a motorcycle in most states and requires the full endorsement. A scooter at or under 50cc typically falls into the moped category. The classification hinges on engine size, and sometimes top speed, not on what the vehicle looks like.

REAL ID and Your License

Whatever class of license you hold, there’s one more thing worth knowing. Since May 7, 2025, every air traveler 18 and older has needed a REAL ID-compliant license, a passport, or another federally accepted ID to board a domestic flight or enter certain federal facilities.11Transportation Security Administration. REAL ID If your license has a gold or black star in the upper right corner, it’s already compliant.12USAGov. How to Get a REAL ID and Use It for Travel

Upgrading a non-compliant license means visiting your state’s licensing agency in person with original documents proving three things: identity (a birth certificate, passport, or permanent resident card), Social Security number (a Social Security card, W-2, or pay stub), and state residency (typically two documents such as a utility bill and a bank statement). Your current legal name must match across all documents, so bring a marriage certificate or court order if your name has changed.

A handful of states, including Michigan, Minnesota, New York, Vermont, and Washington, also offer Enhanced Driver’s Licenses that serve as passport alternatives for land and sea border crossings with Canada and Mexico. EDLs contain an RFID chip and cannot be used for air travel to international destinations.13Department of Homeland Security. Enhanced Drivers Licenses: What Are They?
