DOT & Carrier Compliance

Compliance is where small carriers get hurt — the fines, out-of-service orders, and insurance penalties that follow a missed filing or an incomplete file. Diversified takes the whole burden off your desk, from driver files to federal registrations, so nothing lapses and an audit finds nothing.

Driver qualification files, managed on our software

Our flagship is DQF management: every file, for every driver, for every company, maintained on our own compliance software that monitors each document and alerts before anything expires. DQFs are one of the most-cited findings in a DOT audit — and one of the most preventable.

Every filing, one partner

Beyond driver files, we handle the FMCSA Clearinghouse, MVRs, UCR, MCS-150, IRS Form 2290 (HVUT), IFTA fuel-tax filing, and IRP apportioned registration — plus supervisor and DER training, and consulting on any DOT or FMCSA matter at an hourly rate.

The team that does this every day

You don't need a full-time compliance department. You get people who run these programs for carriers daily, backed by 24/7 support when a real situation arises.

Comprehensive solutions for your compliance needs

FMCSA Clearinghouse Services
DOT & Carrier Compliance

FMCSA Clearinghouse Services

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 File (DQF) Management
DOT & Carrier Compliance

Driver Qualification File (DQF) Management

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.

Motor Vehicle Records (MVR) Services
DOT & Carrier Compliance

Motor Vehicle Records (MVR) Services

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.

MCS-150 Filing Services
DOT & Carrier Compliance

MCS-150 Filing Services

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.

UCR Registration Services
DOT & Carrier Compliance

UCR Registration Services

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.

Supervisor Reasonable Suspicion Training
DOT & Carrier Compliance

Supervisor Reasonable Suspicion Training

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.

DER Training & Certification
DOT & Carrier Compliance

DER Training & Certification

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.

Compliance Consultation
DOT & Carrier Compliance

Compliance Consultation

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.

Form 2290 (HVUT) Filing
DOT & Carrier Compliance

Form 2290 (HVUT) Filing

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.

IFTA Fuel Tax Filing
DOT & Carrier Compliance

IFTA Fuel Tax Filing

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.

Learn more
IRP Apportioned Registration
DOT & Carrier Compliance

IRP Apportioned Registration

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.

What Our DOT & Carrier Compliance Clients Say

Real results from real fleets we've helped stay compliant

“Having all four divisions—compliance, testing, occupational health, and technology—under one roof changed everything. We get our DOT physicals scheduled through Diversified, same platform tracks medical cards and Clearinghouse queries, same team handles random testing. One phone call, one invoice, zero headaches.”
Robert Larson

Owner-Operator · Larson Trucking LLC
“We passed our FMCSA audit with zero violations. Diversified had everything ready—DQF binders, Clearinghouse records, testing documentation, all timestamped and organized. Their review found issues six months before DOT showed up, which saved our safety rating.”
Jennifer Walsh

Safety Director · Platte Valley Carriers
“Before Diversified, DQF management alone was costing us a small fortune. Now we pay a fraction of that and get Clearinghouse monitoring, UCR filing, and audit support included. The ROI was immediate.”
