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.
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.]
