Different Types Of Cdl Licenses

Commercial trucking plays a crucial role in keeping goods and services moving across the country, making it an essential component of the economy. To operate large vehicles, such as trucks or buses, drivers must obtain a Commercial Driver’s License (CDL). This license ensures that drivers are qualified to handle these complex and heavy vehicles safely. 

There are different types of CDL licenses, each tailored to specific kinds of commercial vehicles and driving requirements. Whether you plan to operate a heavy-duty tractor-trailer or drive a school bus, it’s vital to understand the distinctions between CDL classifications. At Truck U, we offer comprehensive training courses to help aspiring drivers obtain their CDL.

What is a CDL License?


A CDL license is a specialized license required for individuals who want to operate large, heavy, or hazardous material vehicles for commercial purposes. The U.S. Department of Transportation (DOT) has established specific requirements for different types of commercial driving jobs. A CDL license not only confirms that a driver is knowledgeable about operating commercial vehicles, but it also ensures that they are able to handle these vehicles under various conditions, adhering to critical safety protocols on the road.

Types Of CDL Licenses


CDL licenses are categorized into three classes: CDL Class A, CDL Class B, and CDL Class C. Here, we will examine CDL Class A and CDL Class B, the most common types of commercial licenses, and the career opportunities that each provides.

1. CDL Class A

CDL Class A is the most versatile and widely sought-after commercial driver’s license type. It allows you to operate combination vehicles with a GCWR of 26,001 pounds or more, provided the towed vehicle exceeds 10,000 pounds. CDL Class A holders can drive large trucks with a tractor (the vehicle that houses the engine) and one or more trailers attached. 

Types of vehicles you can drive with CDL class A

  • Tractor-trailers – These include semi-trucks, 18-wheelers, or “big rigs,” which are commonly used to transport goods over long distances.
  • Tankers – Vehicles designed to transport liquids or gases, often used in industries such as fuel transportation or chemicals.
  • Livestock Carriers – Trucks specifically built to transport livestock, such as cattle or pigs.
  • Flatbeds –  Trucks with open beds, typically used for carrying heavy or oversized cargo like machinery or construction materials.

Career Opportunities With CDL Class A

Holding a CDL Class A opens doors to a variety of trucking careers, including long-haul trucking, regional trucking, and specialized freight transportation. This license allows drivers to operate across state lines, making it ideal for those who enjoy travel and long hours on the road. CDL Class A drivers often have higher earning potential due to the flexibility in the types of loads they can transport. Popular career paths include:

  • Long-Haul Truck Driver
  • Heavy Equipment Transport
  • Hazardous Materials (HazMat) Driver

CDL Class A drivers often command higher wages due to the larger, more complex vehicles they can operate. With this license, you’re not limited to one type of vehicle or job, allowing for a more flexible career.

2. CDL Class B

CDL Class B licenses are generally required for drivers who operate large, single vehicles having a Gross Vehicle Weight Rating 26,001 pounds/more or any such vehicle towing a trailer with a GVWR of no more than 10,000 pounds. Although CDL Class B drivers cannot operate combination vehicles like tractor-trailers, this license is still vital for several important industries.

Types Of Vehicles You Can Drive With CDL Class B

  • Straight Trucks
  • Dump Trucks
  • Passenger Buses
  • Cement Mixers

Career Opportunities With CDL Class B

CDL Class B drivers often find employment in industries requiring local or regional delivery and passenger transportation services. This license is ideal for individuals who prefer a more predictable schedule and shorter driving distances than long-haul truckers. Popular career paths include:

  • Bus Driver
  • Delivery Driver
  • Construction Site Driver

Many CDL Class B jobs allow drivers to work within a specific region, making it easier to maintain a consistent schedule. If you prefer to avoid the long hours on the road that CDL Class A drivers face, CDL Class B offers local driving opportunities that often involve shorter, more predictable routes.
