Understanding the Types of Commercial Driver's Licenses (CDLs)

In the United States, obtaining a Commercial Driver’s License (CDL) is essential for individuals looking to operate commercial vehicles. The CDL is classified into three main types, each designed for specific vehicle categories and driving requirements. Understanding the various types of CDLs is crucial for anyone seeking to enter the commercial driving industry or enhance their employment opportunities within it.

Overview of CDL Types

CDLs are categorized into three classes based on the weight and type of vehicle driven:

  1. Class A CDL
  2. Class B CDL
  3. Class C CDL

1. Class A CDL

A Class A CDL permits drivers to operate:

  • Combination vehicles: This includes any combination of vehicles with a Gross Combination Weight Rating (GCWR) of 26,001 pounds or more, provided the towed vehicle is over 10,000 pounds.
  • Examples:
    • Tractor-trailers
    • Truck and trailer combinations
    • Livestock carriers
    • Flatbeds
Vehicle Type GCWR Towed Vehicle Weight
Combination vehicles 26,001 lbs or more Towed vehicle over 10,000 lbs
Endorsements:

Drivers with a Class A CDL may also need specific endorsements (such as T for double/triple trailers, H for hazardous materials, and X for combination of tank vehicle and hazardous materials) depending on the vehicle type and cargo they intend to transport.

2. Class B CDL

A Class B CDL permits drivers to operate:

  • Single vehicles: Any single vehicle with a Gross Vehicle Weight Rating (GVWR) of 26,001 pounds or more.
  • Straight trucks: Vehicles without a trailer, such as buses.
  • Examples:
    • Buses
    • Delivery trucks
    • Dump trucks
Vehicle Type GVWR
Single vehicles 26,001 lbs or more
Endorsements:

Class B CDL drivers may require endorsements for specific vehicle types, such as:

  • S for school buses
  • P for passenger transport

3. Class C CDL

A Class C CDL is intended for:

  • Vehicles designed to transport: 16 or more passengers (including the driver) or hazardous materials in quantities that require a placard.
  • Vehicles not meeting Class A or B criteria.
  • Examples:
    • Passenger vans
    • Small buses
    • Vehicles transporting hazardous materials (if not over 26,001 lbs)
Vehicle Type Passenger Capacity Hazardous Materials
Vehicles for passenger transport 16 or more Yes (if placarded)
Endorsements:

Class C CDLs may also require specific endorsements, like the aforementioned H for hazardous materials.

How to Determine Which CDL You Need

When deciding which type of CDL to pursue, consider the following questions:

  • What type of vehicle will I be driving?
  • What is the weight of the vehicles I will operate?
  • Will I be transporting passengers or hazardous materials?

Generally, if you plan to operate a combination vehicle exceeding certain weight limits, you will want a Class A. For heavy straight trucks or buses, pursue a Class B. If transporting a limited number of passengers or non-hazardous materials, a Class C may suffice.

Summary of CDL Classes

Class Vehicle Type Weight Consideration Endorsements
Class A Combination vehicles (e.g., tractor-trailers) GCWR of 26,001 lbs or more T, H, X
Class B Single vehicles (e.g., buses, dump trucks) GVWR of 26,001 lbs or more S, P
Class C Passengers (16+) and hazardous materials vehicles GVWR less than 26,001 lbs H
