Compliance infrastructure
Every test, query, medical exam, and document flows seamlessly between divisions—creating a single, integrated compliance ecosystem for DOT and non-DOT customers.

Full DOT and FMCSA compliance for carriers — driver qualification files managed on our own software with expiration monitoring, plus MVRs, Clearinghouse, UCR, MCS-150, 2290, IFTA, and IRP filings, and any other compliance need, from people who do this every day.

Employer occupational health — DOT physicals, respirator medical evaluations and fit testing, post-offer functional capacity testing, fit-for-duty evaluations, and audiograms — delivered in-clinic or on-site by occupational health professionals.

The technology behind everything we do. Every Diversified service runs on a platform we built ourselves — testing, rosters, driver files, Clearinghouse, and lab and MRO integrations in one real-time view. Because we build our own software, we build custom compliance tools for others too.
Each service is designed to integrate seamlessly with your operations.
Full DOT and FMCSA compliance for carriers — driver qualification files managed on our own software with expiration monitoring, plus MVRs, Clearinghouse, UCR, MCS-150, 2290, IFTA, and IRP filings, and any other compliance need, from people who do this every day.
As your C/TPA, we run the FMCSA Drug & Alcohol Clearinghouse for you — company registration, driver enrollment, pre-employment full queries, annual limited queries, and violation reporting. For consortium members, the pre-employment query is part of getting a driver into your pool. $35 per query.
Driver qualification files are one of the most-cited findings in a DOT audit. We manage every DQF for every driver on our own software — tracking each document, alerting before anything expires, and monitoring the MVR and medical card for expiration — so your files are always inspection-ready.
We pull and review motor vehicle records from every state a driver has been licensed — at hire and annually, as DOT requires — flag disqualifying offenses, and file the review in the driver's qualification file. $20 per driver plus state fees at cost.
Your USDOT registration has to be updated with FMCSA every two years — even if nothing changed — or your number is deactivated and your operating authority stops. We file your MCS-150 biennial update on time, handle initial registration and changes, and keep your USDOT record current and active.
Interstate carriers, brokers, and forwarders must register and pay their Unified Carrier Registration (UCR) fee every year — miss it and you risk fines and out-of-service stops. We file your UCR on time, at the right fleet-size tier, with the government fee passed through at cost.
DOT requires every supervisor of CDL drivers to complete at least two hours of reasonable-suspicion training — 60 minutes on drug use and 60 on alcohol misuse (49 CFR 382.603). Ours is led by instructors with law-enforcement backgrounds, delivered online or in-person, for one supervisor or a team.
Your Designated Employer Representative (DER) is the person who receives test results and pulls a driver from duty — and getting those calls right matters. Our DER training walks your DER through their DOT responsibilities: handling results, removals, return-to-duty, and Clearinghouse actions.
Have a DOT or FMCSA question that doesn't fit a standard service — an audit notice, a new-authority setup, a corrective action plan, or a regulation call you can't afford to get wrong? We consult on any DOT and FMCSA compliance matter by the hour, from the team that runs carrier programs every day.
IRS Form 2290 — the Heavy Vehicle Use Tax — is due every year for trucks 55,000 pounds or more, and you need the IRS-stamped Schedule 1 to register your vehicles. We file your 2290 and return your Schedule 1, so a registration never stalls over a missing HVUT proof.
The International Fuel Tax Agreement (IFTA) lets interstate carriers file fuel taxes through one base state instead of every state separately — on a quarterly return. We prepare and file your IFTA returns so the mileage, the fuel, and the math are right and on time.
The International Registration Plan (IRP) is how interstate carriers get apportioned license plates — one registration through your base state covering every jurisdiction you run in, with fees split by mileage. We handle your IRP registration and renewals so your plates stay accurate and current.
Your full-service C/TPA and consortium for DOT and non-DOT drug and alcohol testing — random pool management, every test type, MRO review, SAP coordination, and 24/7 DER support, collected by our own mobile team across Nebraska, Kansas and Iowa.
Diversified Drug Testing is your Consortium/Third-Party Administrator — we run your entire DOT drug and alcohol program. Random pool management, every test type collected by our mobile team across Nebraska and Kansas or in-clinic, plus MRO, SAP, and DER support. $129/year per company.
A driver can't perform safety-sensitive functions until you have a verified negative pre-employment drug test (49 CFR 382.301). Test at our clinics, on-site with our mobile collectors across Nebraska and Kansas, or at a partner site nationwide. MRO-verified. $75 clinic / $95 mobile.
When an accident happens, the clock starts: DOT requires alcohol testing within 8 hours and drug testing within 32 (49 CFR 382.303). Our 24/7 dispatch and our own collectors across Nebraska and Kansas get a driver tested — and every attempt documented — so you meet the window and stay defensible.
When a trained supervisor observes signs of drug or alcohol use, the test must happen fast. Our collectors dispatch same-day, on-site across Nebraska and Kansas, 24/7 — determination and collection documented to keep it defensible. Supervisors need DOT training first; we offer that too.
After a drug or alcohol violation, a driver can't return to safety-sensitive duty until they pass a directly observed return-to-duty test — then complete a SAP-prescribed follow-up plan of unannounced, observed tests (at least 6 in the first year). We run every test and keep the plan on track.
Small fleets can't keep a 24/7 compliance desk — but a post-accident at 2 a.m. or a positive result on a Friday can't wait. We're your around-the-clock backup: emergency collector dispatch, plus expert DER guidance on removals, post-accident calls, and reasonable-suspicion procedures.
Every non-negative drug result must be verified by a qualified Medical Review Officer before it's reported, so a valid prescription never becomes a false positive. Our DOT-qualified MRO network reviews every result — built into our testing, or standalone for specimens you collect.
Our own certified collectors across Nebraska and Kansas bring drug and alcohol testing to your terminal, job site, or accident scene — instead of pulling drivers off the road. Random, pre-employment, post-accident, reasonable-suspicion, and return-to-duty tests, collected on-site. $95 per test.
DOT evidential breath alcohol testing by certified Breath Alcohol Technicians — for random, post-accident, reasonable-suspicion, return-to-duty, and follow-up needs. Collected on-site by our mobile team across Nebraska and Kansas or at any clinic, on DOT-approved devices. $55 per test.
Drug-testing collection for college athletic departments — built around the NCAA banned-substance list, with year-round and event testing, collected on campus by our own collectors and MRO-verified. We provide the testing and the documentation; your department owns the policy and any education.
On-site drug testing for K-12 districts — students in athletics and extracurriculars (per Vernonia and Earls), plus staff and DOT and non-DOT bus drivers. Our collectors come to your schools; results are lab-verified and FERPA-confidential. Your district owns the policy; we handle the testing.
FMCSA requires random drug and alcohol testing every year — 50% of drivers for drugs, 10% for alcohol, by a scientifically valid draw. We run the whole program: a compliant consortium pool, selections every period, and on-site collection across Nebraska and Kansas.
When a driver violates DOT drug or alcohol rules, they can't return to duty without completing the Substance Abuse Professional (SAP) process. Our qualified SAP on staff handles it end to end — the evaluation, the recommended education or treatment, the return-to-duty test, and the follow-up plan.
Not every employer is DOT-regulated — but you still need a drug and alcohol program that's consistent and defensible. We build and administer non-DOT testing on your terms: pre-employment, random, post-accident, and reasonable-suspicion, with instant or lab panels, on-site or in-clinic.
Employer occupational health — DOT physicals, respirator medical evaluations and fit testing, post-offer functional capacity testing, fit-for-duty evaluations, and audiograms — delivered in-clinic or on-site by occupational health professionals.
Fast, FMCSA-compliant DOT physicals at our Lincoln and Beatrice clinics — about 30 minutes, performed by National Registry-certified examiners on staff. For full-service compliance clients, we track every driver's medical card and flag renewals before they lapse.
Objective fit-for-duty and return-to-work evaluations for current employees — a functional work-readiness assessment by licensed physical therapy professionals, matched to the job's real demands. Used after injury or leave, a safety concern, or a workplace incident to decide who can safely return.
OSHA 1910.95 hearing testing for noise-exposed workforces — baseline and annual audiograms with standard-threshold-shift tracking. Test individuals at our Lincoln clinic, or bring our growing on-site mobile service to your factory floor for whole-crew baseline and annual screening.
Fast, low-cost vision screening — Snellen visual acuity and Ishihara color vision — most often built into a custom pre-employment or occupational-health package alongside functional, drug, and hearing testing. Also a quick pre-check that a driver meets the DOT 20/40 standard.
Post-offer back and musculoskeletal screening for material-handling roles — a job-matched functional assessment by licensed physical therapy professionals that confirms a new hire can handle the lifting and documents a musculoskeletal baseline to defend against future injury claims.
Post-offer functional and physical-ability screening built around each job's real demands — lift, carry, push/pull, range of motion — administered by licensed physical therapy professionals and optionally paired with a pre-employment drug screen. Match the right hire to the work before day one.
OSHA respirator fit testing and provider-reviewed medical evaluations for N95 and half-mask respirators, with optional pulmonary function testing. Use DSC for the fit testing, the evaluation, or the complete program — on-site, in-clinic, or at a coordinated event.
The technology behind everything we do. Every Diversified service runs on a platform we built ourselves — testing, rosters, driver files, Clearinghouse, and lab and MRO integrations in one real-time view. Because we build our own software, we build custom compliance tools for others too.
Everything we do runs on technology we built — one platform bringing testing results, consortium rosters, driver files, Clearinghouse status, and lab and MRO integrations into a single real-time compliance view. You see where every driver and requirement stands, without chasing paper.
We built the platform that runs our entire compliance operation — so we know how to build software that solves real operational problems. If your business has a compliance, testing, or workflow problem software could fix, we can build it. Tell us what's broken and we'll scope it.
