Can One Random Pool Include Employees Covered by Different DOT Agencies?

Yes, according to ODAPC. Its 2026 random testing rates page states that employers and C/TPAs subject to more than one DOT agency drug and alcohol testing rule may continue to combine covered employees into a single random selection pool. The same page states that Coast Guard covered employees may be combined with DOT covered employees in drug testing pools. ODAPC lists the minimum random rates for each agency on that page.
