Documentation your safety and legal partners can follow

DOT drug and alcohol testing (regulated)

DOT-covered employers follow federal rules—chiefly 49 CFR Part 40 and the modal regulations for your industry (for example, FMCSA for many motor carriers). Testing is not “whatever the handbook says”; specimen type, collection procedures, laboratories, alcohol testing method (breath or saliva where authorized), medical review, and reporting expectations are set by those rules for employees in safety-sensitive positions.

Your designated employer representative (DER) is the hub for test authorizations and program questions. Random selections are often run through a consortium or third-party administrator, and post-accident or reasonable-suspicion events have timing and documentation pressures that differ from typical office policy workflows. Collectors must execute the correct federal custody steps so results are usable in a regulated program.

We train collectors on applicable DOT collection procedures and coordinate with your DER when on-site questions come up—so the visit matches the order, the right forms are used, and specimens are sealed and routed the way your administrator expects.

Non-DOT workplace testing (policy-led)

Non-DOT programs are driven by your written policy, candidate and employee notice, and state workplace drug-testing law—which varies by state for hiring, random, reasonable suspicion, post-accident, and other testing reasons. Employers often have more flexibility to choose matrices (such as urine, oral fluid, hair, or breath alcohol for alcohol) when law and policy allow, but that flexibility still has to match what your documents actually say and what your third-party administrator or lab accepts.

Observation, donor rights, disciplinary steps, and alternate specimens when someone cannot provide a sample are usually defined in your handbook or program rules—not by Part 40. Practical issues (who can authorize a test, how supervisors document suspicion, how fast you need a collector after an incident) still need clear answers before collection day so the field team is not improvising.

We align specimen types, panels, observation expectations, and paperwork with the policy and orders you provide, and we surface mismatches early—for example, when a site requests a matrix the policy does not authorize or when DOT-covered employees need to be routed to a federal-compliant test instead of a general workplace screen.

Why the split matters on collection day

The same employer can run both DOT and non-DOT programs—for instance, regulated drivers under Part 40 alongside office staff under a handbook-only policy. The wrong form, wrong specimen, or wrong alcohol modality can undermine an entire test for the regulated side while still being “fine” for a purely internal policy screen. Clear intake (who is being tested, under which program, and on what order) keeps collections aligned with how you will defend the result later.
