Types of Commercial Driver’s Licenses

Commercial drivers play a critical role in the U.S. economy. They transport goods, materials, and passengers safely across the country. However, driving large commercial vehicles requires special training and licensing. If you plan to operate a commercial motor vehicle (CMV), you need a commercial driver’s license (CDL).

What is a CDL exactly? This special license is required to operate certain commercial vehicles. The Federal Motor Carrier Safety Administration (FMCSA) sets the rules for obtaining a CDL, and each state issues them. This guide will explain what a CDL is, the different types of licenses, and the additional endorsements required for specialized vehicles.

What Is a Commercial Driver’s License?

A commercial driver’s license (CDL) is a government-issued license that allows drivers to legally operate heavy-duty vehicles, such as semi-trucks, buses, and hazardous material carriers. These vehicles require advanced driving skills and knowledge, which is why CDL holders must undergo extensive training and pass both written and driving tests. 

The type of CDL you need depends on the vehicle’s weight, the type of cargo, and the number of passengers. Some commercial vehicles also require special endorsements for hazardous materials, passengers, or multiple trailers.

The Three Classes of CDLs

There are three main classes of commercial driver’s licenses: Class A, Class B, and Class C. Each class determines what type of vehicle you can drive.

Class A CDL

A Class A CDL is required for operating combination vehicles with a gross combination weight rating (GCWR) of 26,001 pounds or more, as long as the towed trailer is heavier than 10,000 pounds. A combination vehicle is a tractor with one to three attached trailers. 

Examples of Class A vehicles include: 

  • Semi-trucks (tractor-trailers)
  • Livestock carriers
  • Flatbed trucks
  • Tanker trucks
  • Truck and trailer combinations

A Class A CDL license is essentially the “universal” CDL because it allows drivers to operate the broadest range of vehicles. It requires the most training and has the strictest requirements of all CDL classes. 

With a Class A CDL, a driver can operate a commercial vehicle up to 80,000 pounds. 

Class B CDL

With a Class B CDL, a driver can operate a single vehicle that weighs 26,001 pounds or more and tow a trailer that does not exceed 10,000 pounds. 

Examples of Class B vehicles include:

  • Box trucks (large delivery trucks)
  • Cement trucks
  • Garbage trucks
  • Tow trucks
  • City buses and school buses
  • Straight trucks or large cargo trucks without a trailer

Class B license holders can drive large commercial vehicles but cannot tow heavy trailers.

Class C CDL

A Class C CDL is the lowest CDL level, and it’s required to operate a commercial vehicle that doesn’t meet the criteria for a Class B or Class A CDL. It’s commonly used to transport hazardous materials (HAZMAT) or 16 or more people. 

Examples of Class C vehicles include: 

  • Passenger vans (like airport shuttles)
  • Small buses
  • Hazardous material transport vehicles

While a Class C license is the least common type of CDL, it’s the minimum CDL class required to transport dangerous materials or large groups of people.

CDL Endorsements: Specialized Driving Permissions

Some CDL holders need additional endorsements to operate certain vehicles or transport specific cargo. Common CDL endorsements include: 

  • Passenger (P): Required to carry more than 15 people, driver included
  • School Bus (S): Required for operating a school bus; must obtain a P endorsement first
  • Hazardous Materials (H): Required for transporting hazardous substances like gasoline, oil, and possibly dangerous chemicals
  • Tanker (N): Needed to operate a vehicle with a tank attached to haul liquids, gases, or dry loads
  • Tanker & HazMat Combo (X): Permits transport of hazardous materials in tankers
  • Double/Triple Trailers (T): Required to tow two or three trailers at once; only available for Class A CDL holders

These endorsements require extra testing and sometimes additional training and screening. 

Basic Requirements for Getting a CDL

To obtain a CDL, drivers must meet specific requirements. While each state may have slight variations, the general FMCSA requirements include:

  • Be at least 18 years old for intrastate driving (in Florida)
  • Be at least 21 years old to drive across state lines or transport hazardous materials
  • Have a valid, non-commercial driver’s license
  • Have a clean driving record with no disqualifying offenses
  • Pass a Department of Transportation (DOT) medical exam
  • Pass vision and hearing tests
  • Complete Entry-Level Driver Training (ELDT) if applying for a new Class A or B CDL
  • Pass CDL knowledge and skills tests.

Some states require CDL applicants to undergo additional screening and may allow certain exemptions. For example, Florida allows military personnel to apply for a waiver for the CDL skills test. 

Why Are CDLs Important?

Commercial driver’s licenses ensure that only trained and qualified drivers operate large and potentially dangerous vehicles. The strict requirements help improve road safety and reduce accidents caused by untrained drivers. However, trucking accidents still happen. Many accidents can be prevented by following strict federal safety regulations.

If you plan to drive a large commercial vehicle, you need the right CDL for the job. Understanding the differences between Class A, Class B, and Class C licenses is essential. Depending on what you plan to transport, you may also need additional endorsements for hazardous materials, passengers, or specialized vehicles.
