What Is a CDL Endorsement?

A CDL endorsement is an additional qualification added to your Commercial Driver’s License that allows you to operate certain types of commercial vehicles or transport specific types of cargo.

Depending on the job you want and the vehicle you plan to drive, an employer may require one or more endorsements in addition to your CDL.

Adding endorsements can help you:

  • Qualify for a wider range of driving positions
  • Pursue specialized transportation opportunities
  • Build a more versatile commercial driving skill set
  • Stand out to potential employers
  • Prepare for different career paths within the transportation industry

More qualifications can mean more roads to explore.

Drivers interested in industries such as fuel transportation, chemical hauling, manufacturing, environmental services, or other specialized freight may encounter positions requiring a Hazmat endorsement.

Obtaining the endorsement involves additional federal requirements, including required training, knowledge testing, and a Transportation Security Administration security threat assessment.
