Compliance Services We Handle

Six core compliance areas that every motor carrier must manage. Miss any one of them and you risk fines, authority suspension, or getting pulled off the road.

IFTA Reporting

Quarterly International Fuel Tax Agreement filing. We track your miles and fuel purchases across all jurisdictions, calculate what you owe (or what's owed to you), and file on time every quarter so you never face late penalties.

  • Quarterly fuel tax calculations
  • Multi-state mileage tracking
  • Filing deadline reminders
  • Audit-ready record keeping

IRP Registration

International Registration Plan setup and annual renewal for carriers operating across state lines. We handle the apportioned registration process, cab card issuance, and mileage reporting to keep you legal in every state you run.

  • Multi-state apportioned registration
  • Annual renewal management
  • Cab card processing
  • Mileage schedule preparation

Drug & Alcohol Testing

FMCSA-mandated drug and alcohol testing program setup and ongoing management. Includes Clearinghouse registration, random selection pools, pre-employment testing, and post-accident protocols — everything to keep you compliant with 49 CFR Part 382.

  • FMCSA Clearinghouse enrollment
  • Random testing pool management
  • Pre-employment & post-accident tests
  • Reasonable suspicion training

MCS-150 Updates

Biennial motor carrier identification report filing with FMCSA. Your MCS-150 must be updated every two years based on your USDOT number. Miss the deadline and you risk fines up to $1,000 per day and having your USDOT number deactivated.

  • Biennial filing reminders
  • USDOT number maintenance
  • Fleet information updates
  • Deactivation prevention

UCR Registration

Unified Carrier Registration annual filing. Every for-hire motor carrier, broker, freight forwarder, and leasing company operating interstate must register and pay UCR fees each year. We handle the registration before the deadline so your authority stays active.

  • Annual UCR filing
  • Fee calculation by fleet size
  • Deadline tracking
  • Multi-year compliance history

Safety Audit Prep

New entrant safety audit readiness for carriers within their first 18 months of operating authority. We review your driver qualification files, vehicle maintenance records, HOS compliance, and drug testing programs — the same areas FMCSA auditors examine.

  • Driver qualification file review
  • Vehicle maintenance records
  • HOS & ELD compliance check
  • Mock audit walkthrough

DOT Compliance FAQ

Common questions about trucking compliance services, costs, and what happens when things go wrong.

What compliance services does O Trucking offer?

We handle the major DOT compliance requirements that trip up most owner-operators and small fleets: IFTA quarterly fuel tax reporting, IRP multi-state registration, drug and alcohol testing program management (including FMCSA Clearinghouse), MCS-150 biennial updates, UCR annual registration, and safety audit preparation for new entrant carriers. Our compliance package starts at $150/month, and we tailor services to what you actually need based on your operation size and where you run.

How much do compliance services cost?

Our compliance services start at $150/month for basic IFTA and registration management. Full compliance packages — covering IFTA, IRP, drug testing, MCS-150, UCR, and ongoing monitoring — range from $150-400/month depending on fleet size and what's included. Compare that to the cost of a single late IFTA penalty ($50-500/quarter), a missed MCS-150 (up to $1,000/day), or a failed drug test audit ($5,000-10,000), and the math is straightforward. We can also handle individual filings on a per-service basis if you don't need the full package.

Can you help with new authority compliance?

Yes — new authority compliance is one of our specialties. FMCSA requires new entrant carriers to pass a safety audit within their first 18 months or risk losing their authority. We help you build compliant driver qualification files, set up vehicle maintenance programs, establish a drug and alcohol testing program with Clearinghouse enrollment, ensure your ELD and HOS practices meet federal standards, and prepare your records for the actual audit. We also handle the initial filings many new carriers miss: BOC-3 process agent, UCR registration, and getting your MCS-150 current.

What happens if I miss a filing deadline?

It depends on which deadline you miss, but none of the outcomes are good. Late IFTA filing costs $50-500 per quarter plus interest on what you owe. An expired MCS-150 can result in fines up to $1,000 per day and eventual USDOT number deactivation — meaning you can't legally operate. Missing UCR registration can bring fines up to $5,000 and put your operating authority at risk. The worst scenario is a failed safety audit for new entrants, which can result in an "unsatisfactory" rating and loss of your authority entirely. That's why we use automated deadline tracking — so nothing slips through the cracks.

Do I need compliance help if I'm a single truck owner-operator?

Single-truck owner-operators actually have the most to lose from compliance mistakes, because one violation hits your entire operation. You're subject to the same IFTA, IRP, drug testing, and MCS-150 requirements as a 500-truck fleet, but you don't have a back-office team handling it. Most owner-operators we work with came to us after getting hit with a fine or failing a roadside inspection — and wish they'd started sooner. Even basic IFTA and registration management ($150/month) gives you peace of mind that your paperwork is current and you won't get pulled off the road over an administrative oversight.

How do I prepare for a DOT safety audit?

A DOT safety audit examines six areas: general compliance (authority, insurance, operating status), driver qualification (CDL, medical cards, MVR), operational compliance (HOS logs, ELD records), vehicle maintenance (inspection records, repair logs), hazmat compliance (if applicable), and your drug/alcohol testing program. To prepare: gather 12 months of driver files, ELD logs, vehicle inspection reports, maintenance records, and drug test documentation. Make sure every driver's medical certificate is current, every vehicle inspection is documented, and your drug testing program includes random selections at the required 50% annual rate for drugs and 10% for alcohol. We do a full mock audit walkthrough so you know exactly where you stand before FMCSA shows up.
