Types of Commercial Driver’s Licenses in Alabama

Types of Commercial Driver's Licenses in Alabama

Operating a commercial vehicle in Alabama requires more than a standard driver’s license. Depending on the size and type of vehicle you plan to drive, you’ll need a specific class of commercial driver’s license (CDL). Each class comes with its own set of requirements and restrictions that must be followed closely. 

Learning about how the different license types work can help you stay compliant with state law. It also matters if you’re ever involved in a truck accident, since the type of CDL a driver holds can become a factor in a personal injury claim

Class A CDL

A Class A commercial driver’s license in Alabama is required when operating a combination of vehicles with a gross combination weight rating (GCWR) of 26,001 pounds or more, as long as the vehicle being towed weighs more than 10,000 pounds. This is the most common license class for long-haul truck drivers.

Vehicles that typically require a Class A CDL include:

  • Tractor-trailers
  • Flatbed trucks
  • Livestock carriers
  • Tanker combinations

Holding a Class A license also allows you to operate Class B and Class C vehicles in most cases, depending on the endorsements you carry. Since the size and weight of these vehicles are especially high, Class A drivers are held to strict federal and state safety regulations.

Class B CDL

A Class B CDL covers single vehicles with a gross vehicle weight rating (GVWR) of 26,001 pounds or more. It also applies when towing a vehicle that weighs 10,000 pounds or less. This class is common among drivers who operate large single-unit vehicles rather than tractor-trailer combinations.

Examples of vehicles that fall under a Class B CDL include:

  • Straight trucks
  • Large passenger buses
  • Dump trucks
  • Delivery trucks

Class B drivers can also operate Class C vehicles, but they cannot drive Class A combination vehicles. Like Class A holders, Class B drivers must meet medical fitness standards and pass both a written knowledge test and a skills test.

Class C CDL

A Class C CDL is required for vehicles that don’t meet the weight thresholds of Class A or Class B but are designed to carry 16 or more passengers (including the driver) or transport hazardous materials. Many drivers in this category operate smaller commercial vehicles that still pose elevated safety risks.

Vehicles that may require a Class C CDL include:

  • Small passenger vans (16+ passengers)
  • Hazardous material transport vehicles
  • Small HAZMAT tankers

Even though these vehicles are smaller, the nature of their cargo or passenger loads makes proper licensing essential. Drivers carrying hazardous materials must also obtain a HAZMAT endorsement, which involves a background check through the Transportation Security Administration (TSA).

CDL Endorsements and Restrictions

Beyond the three license classes, Alabama also requires specific endorsements for certain types of driving. These endorsements are added to your CDL after passing additional tests. 

Common endorsements include:

  • T: Double/triple trailers
  • P: Passenger transport
  • N: Tank vehicles
  • H: Hazardous materials
  • X: Combination of tank and HAZMAT

Restrictions may also be placed on your CDL based on your testing results and medical history. For example, if you test in an automatic vehicle, your license may be restricted to automatics only.
