Types of Commercial Driver’s Licenses

Commercial driver’s licenses (CDLs) are necessary for individuals who wish to operate large vehicles for business purposes. In the United States, there are various types of commercial driver’s licenses, each designed for different types of vehicles and driving responsibilities. Understanding these categories can help you determine which license you need based on your career goals and the type of vehicle you plan to operate.

What Is a Commercial Driver’s License?

A Commercial Driver’s License (CDL) is a special type of driver’s license required to operate vehicles that meet certain weight and size requirements. This license is necessary for anyone who plans to drive large trucks, buses, or other vehicles intended for commercial use.

The CDL ensures that drivers are trained to handle these vehicles safely and effectively. It is issued by the state where the driver resides, but the standards are regulated federally by the Federal Motor Carrier Safety Administration (FMCSA).

Types of Commercial Driver’s Licenses

In the United States, there are three main classes of commercial driver’s licenses: Class A, Class B, and Class C. Each class has different requirements, vehicle specifications, and driving responsibilities.

Class A CDL

A Class A CDL is the highest class of CDL and is required for individuals who wish to drive combination vehicles. This includes trucks that have a gross combination weight rating (GCWR) of 26,001 pounds or more, provided the towed vehicle weighs more than 10,000 pounds. 

Some examples of vehicles requiring a Class A license are:

  • Semi-trucks (big rigs)
  • Tractor-trailers
  • Double or triple trailers

To obtain a Class A CDL, drivers must pass a skills test and a written knowledge exam and meet medical and age requirements.

Class B CDL

A Class B CDL allows individuals to operate single vehicles that weigh 26,001 pounds or more. Drivers with a Class B CDL can also tow a vehicle weighing up to 10,000 pounds. 

Common vehicles requiring a Class B CDL include:

  • Box trucks
  • City buses
  • Large passenger vehicles

Class B CDLs are generally required for drivers who operate large vehicles but do not need to tow heavier trailers, as is the case with a Class A CDL.

Class C CDL

A Class C CDL is required for individuals who drive vehicles that do not meet the criteria for a Class A or Class B CDL but still need a commercial license. A Class C CDL is typically necessary for: vehicles designed to transport 16 or more passengers, including the driver; vehicles transporting hazardous materials that require placarding, such as certain chemicals or flammable substances.

Drivers with a Class C CDL can operate smaller commercial vehicles, such as passenger vans or smaller trucks, often used for public transportation or delivery services. While this license does not require the same rigorous qualifications as the higher classes, drivers must still meet medical and testing requirements.

How Do You Obtain a CDL?

Obtaining a CDL involves several key steps. 

While specific requirements may vary by state, the general process includes:

  • Complete a CDL training program. Many states require the completion of a CDL training program to ensure drivers understand the rules of the road and vehicle handling. This training is typically provided by accredited schools or through employer-sponsored programs.
  • Pass a written test. Applicants must pass a written knowledge test that covers topics like traffic laws, safety protocols, and the handling of hazardous materials (if applicable).
  • Pass a skills test. A practical driving test is required to demonstrate your ability to handle the vehicle safely and properly.
  • Meet medical and age requirements. Drivers must be in good physical health and meet age requirements (usually 21 or older for interstate driving).

It is important to check the relevant authority for updated rules and regulations.

Understanding the Types of Commercial Driver’s Licenses

Understanding the types of commercial driver’s licenses and their requirements is essential for anyone looking to pursue a career in commercial driving. Whether you’re interested in driving a large truck or operating a passenger bus, obtaining the right CDL is the first step in ensuring a successful career. If you need more information about CDLs or how to get one, it’s best to consult with your state’s motor vehicle department.

If you were injured in a truck crash or other accident involving a commercial vehicle, consult an experienced personal injury attorney.
