NOTE: 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. However, companies (and C/TPAs) doing so must test at or above the highest minimum annual random testing rates established by the DOT Agencies under whose jurisdiction they fall. For example, an employer having both FMCSA- and FRA-covered employees in one pool must test, as a minimum rate, 50% for drugs and 10% for alcohol. PHMSA- and USCG-regulated employees should not to be placed in DOT random alcohol testing pools. Contact the appropriate DOT Agency for additional clarification.

[Please note that USCG covered employees may be combined with DOT covered employees in drug testing pools even though the USCG is now part of the Department of Homeland Security.]
