TSA

Definition

TSA - Transportation Security Administration - administers the security threat assessment required for the CDL hazmat (H) and combined tanker/hazmat (X) endorsements. Drivers seeking the H or X endorsement must submit fingerprints, biographical information, and pay the TSA fee. Background check covers criminal history, immigration status, and certain other disqualifying factors under 49 CFR §1572. Processing typically takes 30–60 days. TSA also runs adjacent transportation-worker programs including TWIC for port access and HME (Hazmat Materials Endorsement) renewals every 5 years. Non-citizens and applicants with disqualifying convictions may be denied even with state-level CDL approval.
