A DOT drug testing consortium can administer a drug and alcohol testing program for covered drivers in Missouri. Start by checking Part 382 applicability: the rules concern covered operations requiring a CDL, rather than every employee who happens to hold one.

Keep the random pool accurate
Tell the administrator when covered drivers join or leave and reconcile the active roster regularly. A departed employee left in the pool and a new covered driver omitted from it create different problems. The agreement should explain how changes are recorded and when the administrator confirms them.
Collection arrangements for Missouri
For Missouri drivers who collect or deliver across a state boundary, ask how the administrator authorizes a collection away from the home base. Confirm the site, DOT collection capability, operating hours and route for reporting a problem. Missouri commercial-driver guidance helps identify the licensing requirements; testing-program coverage must then be checked under Part 382.
Retain control of employer decisions
An employer must retain a designated employer representative (DER); only the employer or an actual employee may serve in that role, not a C/TPA or other service agent. A C/TPA may perform permitted service-agent tasks within the agreed scope. The written service scope should state the limits as clearly as the included work.
A single-driver employer subject to Part 382 generally needs a consortium pool. Enrollment does not replace the employer’s drug and alcohol program responsibilities.
For the wider process, read the service guide and FMCSA drug and alcohol testing guidance. Compare declared coverage and confirm the required service directly with any provider you contact.
