DOT Compliance Checklist: Stay Legal and Keep Your Authority Active

DOT compliance isn't optional — it's the difference between keeping your authority active and getting shut down. Yet many owner-operators and small carriers aren't sure exactly what they need to stay compliant. This checklist covers everything.

Initial Authority Setup

Before you haul your first load, these items must be in place:

• USDOT Number — Required for any commercial vehicle in interstate commerce. Free to obtain through the FMCSA portal.
• MC Number (Operating Authority) — Required for for-hire carriers transporting regulated commodities. Takes 10-20 business days to process.
• BOC-3 Filing — Designates process agents in each state you operate. Must be filed before your MC number becomes active.
• Insurance Requirements — Minimum $750,000 in liability coverage for general freight. Filed with FMCSA as Form BMC-91 or BMC-34.

Ongoing Compliance Requirements

MCS-150 Biennial Update

Every two years, you must update your MCS-150 form with the FMCSA. Your filing month is based on the last digit of your USDOT number. Miss this, and your USDOT status goes to "Not Authorized."

UCR (Unified Carrier Registration)

Annual registration required for interstate carriers. Fees are based on fleet size. Failure to register can result in fines up to $16,000 per violation.

IFTA (International Fuel Tax Agreement)

If you operate in two or more jurisdictions, you need IFTA credentials. Quarterly fuel tax reports are required even if you didn't operate that quarter.

ELD Mandate

Electronic Logging Devices are mandatory for most CMV drivers. Your ELD must be registered with FMCSA and compliant with the technical specifications. Drivers must know how to use them and handle malfunctions.

Drug & Alcohol Testing

DOT requires enrollment in a compliant drug and alcohol testing program including:

• Pre-employment testing
• Random testing (minimum 50% of drivers for drugs, 10% for alcohol annually)
• Post-accident testing
• Reasonable suspicion testing
• Return-to-duty and follow-up testing

CSA Scores and Safety Audits

Your CSA (Compliance, Safety, Accountability) scores affect everything from insurance rates to broker willingness to work with you. The FMCSA tracks seven BASICs (Behavior Analysis and Safety Improvement Categories) including unsafe driving, hours-of-service compliance, and vehicle maintenance.

Monitor your scores regularly through the FMCSA Safety Measurement System (SMS) portal. High scores in any BASIC can trigger interventions ranging from warning letters to compliance reviews.
