USCG Exam Practice · Drug testing — pre-employment, random, post-incident

A marine employer wishes to waive the pre-employment drug test for a job applicant. Which condition would satisfy the waiver requirement under 46 CFR §16.210?

  1. AThe applicant passed a DHHS-certified drug test for a previous employer within the previous 12 months.
  2. BThe applicant passed a chemical test required by this part within the previous six months with no subsequent positive tests during that period.✓ correct
  3. CThe applicant holds a valid USCG credential with no suspension or revocation history.
  4. DThe applicant was subject to a random testing program for at least 30 days during the previous 185 days without a positive result.

Why B is correct

46 CFR §16.210(b)(1) allows waiver if the applicant passed a required chemical test within the previous six months with no subsequent positive tests during the remainder of that period. The 12-month window and 30-day random program participation do not meet the regulatory thresholds.
