How Can an Organization Build an In-House DOT Collection Program?

Some regulated companies, clinics, and multi-site operators want employees to collect DOT specimens on site instead of sending every donor to an outside clinic. An in-house program can work. It still has to meet the same Part 40 collector, DER, and documentation rules as any other collection site.

Qualified collectors come first

Anyone who will perform DOT urine collections must meet 49 CFR 40.33 before starting collector functions: qualification training on the subjects in 40.33(b), five consecutive error-free mock collections with the required scenarios, and a monitor who meets 40.33(c)(2) and attests in writing that the mocks were error-free. Refresher training is required at least every five years (40.33(e)). Collectors must keep documentation and provide it on request to employers and C/TPAs (40.33(g)). If the site will also run DOT oral fluid or alcohol tests, those staff need separate qualification under 40.35 or 40.213. A urine collector is not automatically an oral fluid collector. See whether a urine collector is qualified for DOT oral fluid.

For the career path and step list, link staff to how to become a DOT specimen collector and qualified specimen collector requirements. Do not treat a free lab module as that qualification. See free lab and vendor training versus DOT qualification.

DER contact information for every collection

49 CFR 40.36 requires the employer to give collectors the name and telephone number of the appropriate Designated Employer Representative (DER), and of the C/TPA where applicable, so the collector can reach someone when problems arise during testing. An in-house program still needs that contact path posted for every collector on duty. 49 CFR 40.15(d) also bars the employer from letting a service agent act as DER.

Who will monitor mocks

Organizations that train several collectors each year usually need an in-house mock monitor rather than paying an outside instructor for every cycle. Under 40.33(c)(2), the monitor must be a qualified urine collector who has regularly conducted DOT urine collections for at least one year, or who has conducted urine collector training under Part 40 for at least one year, or who has successfully completed a urine train-the-trainer course. The same three paths appear for alcohol instructors in 40.213(b)(4). Details are in who can monitor DOT mock collections.

Records and site readiness

• Keep each collector's qualification, mock attestation, refresher, and any error correction file where a DER or auditor can retrieve them quickly.
• Stock current Federal Custody and Control Forms and follow the current DOT urine collection guidelines. See the FAQ on 2026 Federal CCF changes for collection sites.
• Confirm supervisors who make reasonable suspicion calls have the mode-specific hours that apply to the employer.

Broader program design topics (policy, random pools, vendor selection) are covered in benefits of an in-house drug testing program and steps to start a drug testing program. This page focuses on the DOT collector and mock-monitor pieces those pages do not detail.

Organizations that want to run their own mocks after staff qualify can enroll a Training Manager path through DOT Urine Collector Train-the-Trainer and the Train-the-Trainer Drug Testing bundle. Initial collector seats can be added with the DOT Urine Specimen Collector Training course.
