Turn your collection site or compliance know-how into a C/TPA business — administering DOT random programs for employer clients. Here is the path, the tools, and the pitfalls.
Set up your entity, EIN, and banking, and carry appropriate liability / errors & omissions insurance.
Know the roles (DER, MRO, SAP, BAT, collector) and the random rules. Getting collector-qualified helps you sell and support.
Build relationships with labs, MROs, SAPs, and collection sites so you can serve clients anywhere.
You need software to run defensible random selections, issue certificates, keep records, and produce MIS.
A C/TPA service agreement that defines responsibilities and keeps the employer as DER and decision-maker.
Usually per-driver per-month or per-selection; know your costs (tokens, collection, lab, MRO) first.
Owner-operators and small fleets need consortium membership — that is your core market.
Run scientifically valid draws at the correct rate, spread through the year, for every client pool.
Prepare each client’s MIS data and be ready to submit when their agency requests it.
Keep test records confidential and for the required retention periods, retrievable on request.
Support the employer; never act as DER or make return-to-duty calls.
A selection with no certificate or pool snapshot is nearly impossible to defend in an audit.
Bunching selections instead of spreading them across the year is a classic finding.
Drawing from a pool that still lists terminated drivers — or omits new hires — breaks equal chance.
