Arkansas CDL Arkansas Hazardous Materials Endorsement Process

Use H for placarded hazardous-material operation and X when the same operation also requires tank authority. The vehicle's base CDL class remains a separate decision based on configuration, weight, passenger design, and cargo.

A first-time H applicant completes Hazardous Materials theory training through a provider listed on the FMCSA Training Provider Registry before taking the state H knowledge test. Arkansas also requires the knowledge test for H renewal and a completed testing packet for the renewal transaction.

Arkansas requires a TSA security threat assessment to obtain, renew, or transfer an HME. The process includes fingerprints and a federal background check. A person who does not successfully complete the assessment cannot receive the endorsement.

DFA advises allowing at least 90 days for the threat-assessment process. Begin early enough that fingerprinting, federal review, state testing, and final issuance can finish before the current authority expires.

Arkansas does not transfer the remaining validity period of an HME issued by another state. A transferring driver must complete the Arkansas and TSA steps required for the new endorsement rather than relying on the old state's expiration date.

Apply the rule to the exact Arkansas vehicle, credential, date, trip, test stage, and operating facts. The current DFA and State Police pages, current controlling law, federal requirements, and the current official manual govern when an older publication conflicts.
