body: Getting a CDL endorsement is a sequence, not a single application: which test type is required (knowledge-only vs. knowledge plus skills), whether the endorsement can be added at the commercial-learner's-permit (CLP) stage or only after a full CDL, and — for the hazardous materials endorsement specifically — a separate federal TSA security threat assessment that gates issuance independent of the state testing process, with its own renewal clock. Each record is one endorsement type, carrying the required test, its CLP eligibility, and any federal prerequisite beyond state testing. Answers 'can I get my tanker endorsement on a learner's permit', 'do I need a background check for a hazmat endorsement', 'how often does the TSA hazmat clearance have to be renewed'.
