How often must a hazmat-endorsed driver retake the security threat assessment?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

Every 5 years

  1. A Once for life
  2. B Every 10 years
  3. C Every 5 years
  4. D Every year

Why this is the answer

The TSA security threat assessment for the hazmat endorsement must be renewed every 5 years. The renewal process is essentially the same as the initial: fingerprinting, background check, immigration status verification, and payment of the TSA fee. The state may also require its own endorsement renewal alongside the federal threat assessment. Drivers who let the threat assessment lapse lose the H endorsement and must reapply, including the full renewal process and waiting period. Plan well ahead — the process can take 30-60 days, sometimes longer. Maintaining the endorsement continuously is much easier than letting it lapse and re-applying.
