Why This Matters

The #1 compliance mistake new carriers make is operating before all federal filings are complete. Running without active authority, missing a BOC-3, or letting UCR lapse can result in fines, authority revocation, and personal liability. Everything in this module must be in place before your first load.

USDOT Number

Any motor carrier operating in interstate commerce must register with FMCSA and obtain a USDOT number via Form MCS-150 at the FMCSA Portal. The USDOT number must be displayed on both sides of every commercial vehicle. You must file a biennial update (also on Form MCS-150) every two years — FMCSA will deactivate numbers that lapse without update.

Operating Authority (MC Number)

For-hire carriers — those paid to transport others' goods — must obtain operating authority (an MC number) in addition to a USDOT number. Private carriers hauling their own goods need only a USDOT number. Apply through the FMCSA Portal. There is a 10-day protest period after filing; authority becomes active in 20–25 days if no protest is filed. Do not dispatch loads until authority is confirmed active.

Types of authority: Common (serve any shipper), Contract (specific shippers under written contract), and Broker (arrange but not transport freight). Most carriers start with common or contract authority.

BOC-3 — Process Agents

Before authority is granted, you must file a BOC-3 designating a process agent in every state of operation. Process agents accept legal service on your behalf. You cannot hire agents individually — use a blanket BOC-3 filing service (typically $35–75 one-time) that covers all 48 contiguous states. FMCSA will not activate your authority without an active BOC-3 on file.

UCR — Unified Carrier Registration

All motor carriers, brokers, freight forwarders, and leasing companies in interstate commerce must register annually under UCR. Fees range from $46 (0–2 vehicles) to $44,836 (1,001+ vehicles) based on fleet size for 2025–26, rising to $55 and $54,165 from 2027. Register at UCR.gov in your base state. The annual deadline is January 1. Operating without current UCR is a violation and can result in authority suspension.

New Entrant Requirements

New carriers are designated "new entrants" for an 18-month monitoring period, and the New Entrant Safety Audit comes early in it: within 12 months of beginning operations for property carriers, or 120 days for passenger carriers (49 CFR 385.3). FMCSA or a state partner reviews your driver qualification files, hours of service records, and maintenance documentation. Failing the audit — or not completing it — results in authority revocation. Use your first months to build compliant systems, not scramble before the audit.

Driver Qualification Files

Every driver must have a Driver Qualification (DQ) file maintained at your principal place of business. Under 49 CFR 391.51, the file must contain: employment application, motor vehicle record (MVR) from each state licensed in the past 3 years, annual review of driving record, annual driver's certificate of violations, road test certificate (or equivalent), medical examiner's certificate, and the Clearinghouse query consent form. Files must be retained for 3 years after the driver's last day of employment.

CDL Classes and Endorsements

Class A — any combination of vehicles with GCWR over 26,001 lbs where the towed vehicle exceeds 10,001 lbs. Required for most tractor-trailer operations. Class B — single vehicle over 26,001 lbs, or such a vehicle towing one not exceeding 10,001 lbs (straight trucks, large buses). Class C — vehicles under 26,001 lbs carrying 16+ passengers or placarded hazmat.

Key endorsements: H (hazardous materials), N (tank vehicles), P (passengers), S (school bus), T (double/triple trailers), X (combination of tank + hazmat).

DOT Medical Certificate

CDL holders must pass a DOT physical conducted by a certified Medical Examiner listed in the FMCSA National Registry. The certificate is valid for up to 2 years (shorter for conditions such as controlled blood pressure or diabetes). Carriers must maintain a copy of the current medical certificate in the DQ file and verify it has not lapsed. If a CDL holder's medical certificate expires, their CDL is automatically downgraded by the state.

Drug & Alcohol Clearinghouse

The FMCSA Drug & Alcohol Clearinghouse is a federal database of CDL drivers with drug and alcohol violations. Carriers must run a full query before hiring any CDL driver and a limited annual query for all current CDL drivers. Employers must also report any violations to the Clearinghouse within 3 business days. Drivers must not perform safety-sensitive functions if they have an unresolved violation in the Clearinghouse.

Hours of Service — Property Carriers

The HOS rules for property-carrying operations under 49 CFR Part 395:

• 11-Hour Driving Limit — may not drive more than 11 hours after 10 consecutive hours off duty
• 14-Hour On-Duty Window — may not drive after the 14th hour after coming on duty, regardless of breaks taken
• 10-Hour Off Duty — must take at least 10 consecutive hours off before the next driving shift
• 30-Minute Break — must take a 30-minute break after 8 cumulative hours of driving
• 60/70-Hour Rule — may not drive after 60 hours in 7 consecutive days or 70 hours in 8 consecutive days
• 34-Hour Restart — may restart 60/70-hour clock after 34 consecutive hours off duty

ELD Mandate

ELDs (Electronic Logging Devices) automatically record driving time and are required for most CDL drivers subject to HOS rules. Exempt from the ELD mandate: short-haul drivers (return to home terminal within 12 hours, no log required), drivers of vehicles manufactured before model year 2000, drivers operating under a 100 or 150 air-mile radius exemption, and driveaway-towaway operations. ELDs must be certified and registered with FMCSA.

Annual Vehicle Inspection

Every commercial motor vehicle must be inspected at least once every 12 months by a qualified inspector (49 CFR 396.17). The inspection must cover brakes, coupling devices, exhaust system, fuel system, lights, steering, suspension, tires, wheels, and windshield. A completed inspection report must be retained for 14 months. The vehicle must display a current inspection sticker or report. Operating a CMV without a valid annual inspection is an out-of-service violation.

Driver Vehicle Inspection Reports (DVIR)

Drivers must complete a DVIR at the end of each day's work if they found or were told of any defect (49 CFR 396.11). The pre-trip inspection is the driver's responsibility before operating the vehicle. The DVIR must identify the vehicle, list any defects found, and be signed by the driver. The carrier must certify repairs or certify no defects require repair before the next trip. Retain DVIRs for 3 months.

Roadside Inspection Levels

FMCSA and state enforcement officers conduct roadside inspections classified into six levels:

• Level 1 (North American Standard) — most thorough; covers driver credentials, logs, hours, alcohol/drugs, and full vehicle inspection
• Level 2 (Walk-Around) — all Level 1 driver checks + walk-around vehicle inspection (no underbody)
• Level 3 (Driver Only) — driver credentials, license, medical certificate, HOS logs, seatbelt; no vehicle inspection
• Level 4 (Special Studies) — specific component or regulatory area
• Level 5 (Vehicle Only) — full vehicle inspection without driver present
• Level 6 (Enhanced NAS) — radioactive material shipments

CSA — Compliance, Safety, Accountability

FMCSA's CSA program uses roadside inspection and crash data to measure carrier safety through 7 BASIC categories: Unsafe Driving, HOS Compliance, Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, Hazardous Materials Compliance, and Crash Indicator. Each violation is assigned a severity weight (1–10) and a time weight (violations in the past 6 months count most). High CSA scores trigger FMCSA interventions and raise insurance premiums. Monitor your scores at SMS.FMCSA.dot.gov.

Out-of-Service Criteria

Out-of-service (OOS) violations immediately remove a driver or vehicle from service. Common driver OOS violations: HOS violations (driving past limits), invalid CDL or medical certificate, alcohol/drug test failure, using a handheld phone. Common vehicle OOS violations: inoperable headlights/brake lights, brake adjustment violations, tire conditions (tread depth below 2/32 inch on steer axles), steering defects, and fuel/oil leaks. OOS violations are weighted most heavily in CSA calculations.

Preventive Maintenance

A written preventive maintenance (PM) program is a best practice and reduces OOS violations significantly. PM schedules should track oil changes, brake inspections, tire rotations, and safety-critical component checks by mileage or time intervals. Retain maintenance records for at least 12 months and inspection reports for 14 months. A strong PM program is the first thing FMCSA auditors review and directly impacts your Vehicle Maintenance BASIC score.

Why Insurance is a Compliance Issue

Insurance isn't just financial protection — it's a federal operating requirement. FMCSA mandates minimum liability coverage as a condition of your operating authority. If your policy lapses, cancels, or falls below minimum limits, your insurer notifies FMCSA and your authority can be suspended within 30 days. No active insurance = no authority = no legal operations.

MCS-90 Endorsement

The MCS-90 is a mandatory endorsement attached to every motor carrier's liability policy. It serves as a federal financial responsibility guarantee: the insurer agrees to pay any judgment for bodily injury or property damage arising from motor carrier operations, up to the federal minimum limits, even if the carrier violated policy conditions. This protects the public — not the carrier. After paying an MCS-90 claim, the insurer has the right to seek full reimbursement from the carrier.

Minimum Liability Limits

FMCSA sets minimum liability requirements based on the type of cargo transported:

• $750,000 — for-hire carriers of non-hazmat property
• $1,000,000 — for-hire carriers of oil or certain hazardous materials
• $5,000,000 — carriers of hazardous materials (Class A/B explosives or radioactive material in large quantities)
• $5,000,000 — household goods carriers (HHG) over certain thresholds

These are federal minimums. Many shippers and brokers require $1,000,000 or higher in their carrier contracts regardless of cargo type.

Cargo Insurance

FMCSA does not set a minimum cargo insurance requirement for most property carriers (household goods carriers are an exception). However, most broker contracts and shipper agreements require cargo coverage. Under the Carmack Amendment (49 U.S.C. §14706), the carrier is the insurer of last resort — legally liable for the full value of cargo unless the carrier can prove one of five defenses: act of God, act of public enemy, act of the shipper, inherent nature of the cargo, or act of public authority.

BMC-91 and BMC-91X

Once you have an MCS-90 endorsement on your policy, your insurer files a BMC-91 (insurance) or BMC-91X (surety bond) form directly with FMCSA to confirm your financial responsibility is on file. Your authority will not be activated — and will be suspended if your coverage lapses — unless a current BMC-91/91X is on file with FMCSA. Insurers must give 30 days advance notice to FMCSA before canceling the filing.

The Owner-Operator Coverage Gap

Owner-operators leased to a motor carrier are covered by the carrier's primary liability while under dispatch. But when operating the truck for personal use or between loads without a load assignment (bobtailing or deadheading off dispatch), the carrier's policy typically does not apply. Owner-operators need Non-Trucking Liability (NTL) or Bobtail insurance to fill this gap. This coverage is the owner-operator's own responsibility under the lease agreement.

IFTA — How Fuel Tax Apportionment Works

The International Fuel Tax Agreement (IFTA) simplifies fuel tax reporting for carriers operating in multiple jurisdictions. Instead of filing with each state separately, you file one quarterly return with your base state, which reconciles taxes among all member jurisdictions based on miles driven there. IFTA applies to qualified motor vehicles: vehicles with 2 axles and GVWR over 26,000 lbs, or vehicles with 3 or more axles regardless of weight, operating in 2 or more IFTA member jurisdictions.

The calculation: total miles driven in each jurisdiction ÷ total miles driven × total gallons of fuel purchased = gallons of fuel "used" in that jurisdiction. Multiply by that state's tax rate to get tax owed. If you bought more fuel in a state than you "used" there, you get a credit.

Quarterly Filing

IFTA returns are due quarterly: April 30 (Q1), July 31 (Q2), October 31 (Q3), and January 31 (Q4). Late returns incur a $50 penalty plus interest on unpaid taxes. Keep fuel receipts and mileage records for each jurisdiction — IFTA records must be retained for 4 years and are subject to audit. Common audit triggers: significant mileage discrepancies, mileage per jurisdiction that doesn't match routes, or fuel purchases that don't align with reported mileage.

IRP — International Registration Plan

IRP apportions registration fees based on the percentage of miles operated in each member jurisdiction. Instead of registering in every state you operate in, you register once in your base state and receive one apportioned plate and cab card that authorizes operation everywhere. Fees are calculated by: (miles in jurisdiction ÷ total miles) × registration fee for that state. First-year carriers use estimated miles; subsequent years use actual prior-year miles.

The IRP cab card must be in the vehicle at all times. It lists all the states/provinces your vehicle is authorized to operate in. Operating without a current cab card — or operating in a state not listed — is a registration violation.

UCR Annual Registration

UCR (Unified Carrier Registration) is separate from IRP — it's not a registration plate, it's a fee program. Fees are based solely on fleet size, not miles. All interstate carriers, brokers, freight forwarders, and leasing companies must register annually by January 1 (many states grant a grace period to March 1). Register at UCR.gov in your base state. Keep your UCR confirmation as proof of registration — enforcement officers can check UCR compliance at roadside.

Special State Weight-Distance Taxes

Four states impose weight-distance or highway use taxes in addition to IFTA:

• Oregon — Weight-Mile Tax for trucks over 26,000 lbs. Oregon is not an IFTA member for WMT purposes. Register separately with Oregon DOT. Pay based on miles driven and vehicle weight.
• New Mexico — Weight Distance Tax for trucks over 26,000 lbs. File monthly or quarterly with NMDOT.
• New York — HUT (Highway Use Tax) for trucks over 18,000 lbs. Requires HUT decal + quarterly mileage reporting.
• Kentucky — Weight Distance Tax for trucks over 60,000 lbs. File quarterly with KY Revenue Cabinet.

Why California Is Different

California has its own air quality regulations, registration requirements, and labor laws that apply to motor carriers operating in the state — independent of FMCSA rules. For fleets based in California or making frequent CA deliveries, state compliance is often more complex than federal compliance. The California Air Resources Board (CARB) and the California DMV are the two primary agencies to understand.

CARB Fleet Rules

Advanced Clean Trucks (ACT) — requires truck manufacturers to sell increasing percentages of zero-emission vehicles. Doesn't directly mandate fleet purchases, but signals the direction of CA fleet requirements.

Transport Refrigeration Units (TRU) — diesel-powered refrigeration units on trailers must meet CARB emissions standards and register in the TRU ATCM (Air Toxic Control Measure) program. Carriers with refrigerated trailers operating in CA must verify compliance by trailer VIN.

Drayage Truck Registry — trucks accessing California ports and railyards must be registered in CARB's Truck and Bus Regulation and listed in the Drayage Truck Registry. Unregistered trucks are turned away at the gate.

CA Biennial Inspection of Terminals (BIT)

California's BIT program requires motor carriers with a terminal in California that operate 3 or more vehicles to submit to a terminal inspection every 25 months by a CA Highway Patrol Motor Carrier Safety officer. The inspection covers maintenance records, driver records, and a vehicle inspection. Failing a BIT inspection can result in an unsatisfactory rating, which triggers follow-up inspections and can affect CA operating permit status.

AB5 and Owner-Operators in California

California AB5 (2019) imposes the ABC test to determine whether a worker is an employee or independent contractor. The critical "B prong" requires that the work be outside the usual course of the hiring company's business. For trucking companies, owner-operators hauling freight are core to the business — making it nearly impossible to classify them as independent contractors under AB5. This has led most CA carriers to either employ their drivers directly or lease through qualifying broker arrangements. Misclassification carries significant wage, tax, and workers' compensation liability.

CA-Specific Registration Fees

In addition to IRP apportioned registration, California charges:Weight fees based on unladen weight (vehicles over 10,001 lbs), Motor Carrier Permit (MCP) required for carriers of property operating CMVs in CA with a GVWR over 10,001 lbs ($16–1,900 depending on weight; passenger-only carriers need a CPUC TCP instead), and MCRT (Motor Carrier Road Tax) for carriers hauling for-hire in CA. All commercial vehicles must also have a CA Number displayed on both sides of the cab if based in California.

Managing Multi-State Compliance

The complexity compounds when you operate across multiple states. Oregon WMT, NY HUT, and KY weight-distance all have separate filing systems. CA CARB requires separate registration from federal requirements. The practical solution: a compliance calendar that tracks each state's filing deadlines separately, and a designated compliance manager (or third-party service) responsible for each program. ATD's compliance monitoring platform tracks these deadlines across all jurisdictions so nothing falls through the cracks.
