DOT Compliance Services 2026: Full-Service FMCSA Compliance for Trucking Companies

What DOT Compliance Is and What a Full-Service Program Includes

DOT compliance is the umbrella of federal and state requirements that motor carriers must meet to operate legally and safely in the United States. In practice, it means aligning your company with Federal Motor Carrier Safety Regulations (FMCSRs), maintaining qualified drivers and safe equipment, filing registrations on time, managing drug & alcohol testing, and staying audit-ready year-round. In Simplex Group as a full-service trucking compliance partner, we centralize all of that work so you can focus on running loads, not chasing regulations.

A robust DOT compliance service typically covers: 

• Obtaining and maintaining your USDOT/MC authority
• Biennial updates (MCS-150)
• BOC-3 process agents
• UCR registration
• FMCSA Clearinghouse enrollment and queries
• Consortium (C/TPA) drug & alcohol testing
• Driver Qualification Files (DQF) and MVR monitoring
• ELD/HOS policy and training
• IFTA fuel tax and 2290 HVUT
• Hazmat registration as applicable
• Safety audits and corrective action plans. 

In Simplex Group, we don’t just “set it and forget it.” We keep driver qualifications in order, file and maintain your documentation, and proactively calendar renewals so there are no bumps in the road.

Because compliance is dynamic, we begin with a structured gap assessment against Parts 382, 383, 390–399, and state overlays. We then implement a maintenance cadence; monthly, quarterly, or tailored to your operation. With 20 years of helping trucking entrepreneurs grow, we’ve learned that consistency beats intensity: small, predictable actions avoid costly violations, out-of-service orders, and lost hauling opportunities.

DOT Compliance Services Benefits for Carriers and Owner-Operators

A well-run FMCSA compliance program delivers measurable business value:

• Fewer violations, fewer surprises. Proactive monitoring of MCS-150, UCR, Clearinghouse queries, DQF content, and ELD/HOS reduces enforcement touchpoints and CSA score exposure.
• Time back to dispatch. Instead of juggling portals and forms, your team relies on a single point of contact. Our experts file, track, and maintain the paperwork end-to-end.
• Audit readiness. Organized Driver Qualification Files, records of duty, and drug & alcohol documentation mean you can withstand a new-entrant safety audit or focused review without scrambling.
• Faster onboarding and scaling. Standardized checklists for adding drivers, units, and lanes keep growth clean.
• Confidence with customers. Shippers and brokers notice when your documentation is current and verifiable.

We support clients nationally, with offices in Texas (Dallas & Houston), California, and Florida, to provide responsive, local service. Our full-service approach means we manage the day-to-day details, like ensuring driver qualifications remain current and your filings are maintained, so compliance doesn’t slow your operation. When you need a seasoned partner, our team is ready to assist today.

Our DOT Compliance Services include

MCS-150 Biennial Update & Operating Authority (USDOT/MC)

We obtain and maintain your USDOT/MC credentials, keep your legal name/Mailing/Principal Place of Business accurate, and file the MCS-150 biennial update on time (or sooner if your profile changes). Beyond the form, we verify power units, mileage, cargo classes, and safety contact info to keep roadside data consistent and avoid mismatches that trigger inspections or audits.

BOC-3 and UCR (Annual Registration)

We file your BOC-3 (Designation of Process Agents) and keep it active so new authority moves smoothly from “granted” to “operational.” Each year we handle UCR registration, right-sizing your bracket to your fleet count and documenting proof for brokers and shippers. Our calendaring ensures renewals don’t slip into penalties.

Clearinghouse & Drug/Alcohol Testing (C/TPA)

We enroll carriers in the FMCSA Clearinghouse, manage pre-employment and annual queries, and administer a compliant consortium/third-party administrator (C/TPA) program. From policy creation to random selections, result management, and supervisor reasonable-suspicion training, we ensure Part 382 requirements are met and documented.

Driver Qualification Files (DQF) & MVR Monitoring

We build and maintain complete Driver Qualification Files—application, previous employer checks, medical certificate tracking, road tests/Equivalent, annual reviews, and MVRs. Our system flags expirations (med cards, licenses, endorsements) and keeps each file audit-ready. In our experience, disciplined DQF maintenance is the single best predictor of a smooth audit outcome.

IFTA & 2290 HVUT

We prepare and file IFTA returns using clean trip/fuel data and manage 2290 Heavy Vehicle Use Tax filing with stamped Schedule 1 for registrations. When jurisdictions issue notices, we respond with reconciliations and proof to close the loop quickly.

ELD/HOS & Supervisor Training

We help you select and configure ELD solutions, align HOS rules with your operation (e.g., short-haul, adverse conditions, split sleeper options), and train drivers and supervisors to prevent form-and-manner and clock management errors. Periodic log audits and coaching keep violations trending down.

State Permits & Insurance Documentation

From IRP/Apportioned plates to state fuel or weight permits and hazmat registration, we manage the paperwork and coordinate with your insurer to issue timely COIs. The result: cleaner roadside stops and fewer delays at the dock.

How Do We Work?

1. Express Assessment. We review your authority, portal access, driver roster, equipment list, policies, and recent violations. You get a concise risk map: what’s current, what’s missing, and what’s due next.
2. Compliance Plan. We translate the risk map into actions: which registrations to file (MCS-150, UCR, BOC-3), which driver files to complete, which training to schedule, and which data feeds to automate (ELD, MVR). We sequence tasks to clear immediate risks first (e.g., Clearinghouse annual queries, 2290 proof for registrations).
3. Maintenance. We operate your calendar and documentation—filing, updating, and archiving records so you remain audit-ready. Practically speaking, we keep your driver qualifications in order and maintain all paperwork, so operations continue without disruption. Our team of experts is available to answer questions and guide you through regulatory changes as they arise.
