CDL Endorsement
Additional certifications added to a CDL that permit hauling specific cargo types.
Definition
CDL endorsements are additional certifications that expand what types of cargo or vehicles you can operate. Common endorsements: H (Hazmat), N (Tanker), T (Doubles/Triples), P (Passenger), S (School Bus), X (Hazmat + Tanker combo). Each requires passing an additional written test, and hazmat requires a TSA background check. Endorsements significantly increase earning potential.
Why it matters to you
Endorsements are the cheapest way to widen the jobs you qualify for. Tanker, hazmat and doubles/triples all unlock freight that pays a premium precisely because fewer drivers hold the letters. Some require a knowledge test only; hazmat also needs fingerprinting and a background check that takes time. Getting them before you apply puts you in a stronger position than promising to get them later.
