- 49 CFR §366(Designation of Process Agents Rule)
- The federal regulation that requires every interstate motor carrier, broker, and freight forwarder to file Form BOC-3 designating a process agent in every state where they operate. The BOC-3 form itself is the implementation of this rule. Codified in Title 49 of the Code of Federal Regulations, Part 366.
- See also: BOC-3, Process Agent, FMCSA
- 49 CFR Part 387(Minimum Levels of Financial Responsibility)
- The federal regulation that sets minimum public-liability insurance amounts for motor carriers - typically $750,000 for general freight, $1 million for oil-carrying tankers, $5 million for hazmat. Compliance is proven by the BMC-91 / BMC-91X filing on file with FMCSA.
- See also: BMC-91, MC Authority
A
B
- Blanket Process Agent
- A process-agent service that maintains an authorized agent in every state, allowing a carrier to satisfy the BOC-3 designation requirement with a single filing rather than identifying separate agents in 49+ jurisdictions individually. FastBOC3 Filing operates as a blanket process agent across every state we serve.
- See also: BOC-3, Process Agent
- BMC-84(Property Broker Surety Bond)
- A $75,000 surety bond required of property brokers and household-goods brokers under 49 USC §13906. The bond protects motor carriers from broker non-payment. Premiums are credit-driven and typically run 1–4% of the face value annually for new brokers ($750–$3,000/year). Filed with the FMCSA on Form BMC-84 by the surety company.
- See also: BMC-85, Property Broker, MC Authority
- BMC-85(Trust Fund Agreement)
- An alternative to the BMC-84 surety bond - brokers may instead deposit $75,000 in cash into a trust fund maintained by a financial institution. Same protective purpose as the bond; different funding mechanism. Most brokers prefer the bond because it doesn't lock up working capital.
- See also: BMC-84, Property Broker
- BMC-91(BMC-91X · Public Liability Insurance Filing)
- The FMCSA insurance filing that proves a motor carrier maintains the federal minimum public-liability coverage (typically $750,000, higher for hazmat or passenger). Filed by the insurance company on the carrier's behalf as Form BMC-91 (single insurer) or BMC-91X (multi-insurer schedule). Required before operating authority activates and must remain on file continuously.
- See also: MC Authority, SAFER, Authority Reinstatement
- BOC-3(Designation of Process Agents · Form BOC-3)
- A federal FMCSA filing that names a process agent in every state authorized to accept legal service of process on behalf of an interstate motor carrier, broker, or freight forwarder. Required under 49 CFR §366 before operating authority can activate. Without one, an MC or FF number is issued but shows "NOT AUTHORIZED" on SAFER and cannot legally be used.

C
- CDL(Commercial Driver's License)
- A state-issued license required to operate commercial motor vehicles in classes A, B, or C. Federal minimum standards are set by 49 CFR Part 383, but the license itself is issued by the state where the driver is domiciled. Endorsements (H, N, P, S, T, X) certify additional qualifications such as hazmat or passenger transport.
- See also: Hours of Service, Medical Examiner Certificate, CSA Score
- CMV(Commercial Motor Vehicle)
- A vehicle used in commerce that meets one of: 10,001+ lbs gross vehicle weight, transports passengers for compensation, or transports hazardous materials in placardable quantities. Federal compliance regulations (CDL, HOS, ELD, drug/alcohol clearinghouse) attach to CMVs. Brokers and freight forwarders without CMVs operate under different rules - including the BOC-3 self-designation carve-out.
- See also: CDL, ELD, Hours of Service
- Common Carrier
- A motor carrier authorized to haul freight for the general public under published tariffs. Subject to FMCSA operating authority and the full BOC-3 / insurance / UCR compliance stack. Distinct from contract carriers, which operate under negotiated agreements with a limited group of shippers.
- See also: Contract Carrier, MC Authority, OP-1
- Contract Carrier
- A motor carrier that hauls freight under contract for a specific shipper or limited group of shippers, rather than for the general public. Holds FMCSA contract-carrier authority and the same BOC-3 / insurance requirements as a common carrier, but operates under negotiated rates rather than published tariffs.
- See also: Common Carrier, MC Authority
- CSA Score(Compliance, Safety, Accountability · SMS)
- The FMCSA's carrier-safety scoring system, calculated from roadside inspection violations, crashes, and other compliance data over a rolling 24-month window. Scores are organized into seven BASICs (Behavior Analysis and Safety Improvement Categories). Brokers and shippers routinely check CSA scores before assigning loads; high scores trigger DOT interventions.
- See also: SAFER
D
- DBA(Doing Business As · Trade Name)
- A registered alternate business name a company operates under, distinct from its legal entity name. FMCSA records track both the legal name and any DBAs. A BOC-3 designation is keyed to the legal entity, so a DBA change typically doesn't require a new BOC-3 unless the underlying LLC or corporation also changes.
- See also: MC Authority, USDOT Number
- Drug & Alcohol Clearinghouse(FMCSA Clearinghouse)
- A federal database the FMCSA launched in 2020 that records every drug- or alcohol-related test failure, refusal, or return-to-duty status for CDL drivers. Carriers must query it pre-employment and annually for every driver. Part of 49 CFR Part 382 compliance.
- See also: CDL, CSA Score
E
- ELD(Electronic Logging Device)
- A federally-mandated device that automatically records a driver's on-duty / driving / off-duty time, replacing paper logs. Required for most interstate CDL drivers under 49 CFR Part 395. The ELD must be on the FMCSA's registered-devices list; uncertified devices trigger out-of-service violations at roadside.
- See also: Hours of Service, CDL
F
- FMCSA(Federal Motor Carrier Safety Administration)
- The agency within the U.S. Department of Transportation responsible for regulating commercial motor carriers, brokers, and freight forwarders operating in interstate commerce. Issues operating authority (MC numbers), publishes the safety regulations in 49 CFR Parts 350–399, and operates the SAFER and Licensing & Insurance public-records systems.
- See also: MC Authority, USDOT Number, SAFER
- FMCSA L&I System(Licensing & Insurance · L&I Public Records)
- The FMCSA's public-records system for operating authority, BOC-3 status, insurance filings, and safety data. Accessible at li-public.fmcsa.dot.gov. Brokers, shippers, and verification services check L&I before doing business with a new carrier. Process-agent providers (including FastBOC3) appear on L&I's registered-agent list.
- See also: SAFER, FMCSA, MC Authority
- Form 2290(HVUT · Heavy Vehicle Use Tax)
- An IRS-administered federal tax (not FMCSA) imposed on commercial vehicles weighing 55,000+ lbs gross vehicle weight that operate on public highways. Filed annually using Form 2290; the IRS returns a stamped Schedule 1 as proof of payment, which most states require before issuing license plates.
- See also: IFTA, IRP
- Form OP-1(FF)(Freight Forwarder Application)
- The FMCSA application form a freight forwarder files to obtain MC-FF operating authority. $300 filing fee. Like the standard OP-1 for motor carriers, OP-1(FF) opens a 21-day vetting window during which the applicant's BOC-3 + insurance must land for the authority to activate.
- See also: OP-1, MC Authority, Freight Forwarder
- Freight Forwarder(FF Authority · MC-FF)
- An entity that assembles, consolidates, and tenders freight to motor carriers for line-haul transport, often issuing its own bills of lading and assuming carrier liability for the freight. Holds FMCSA freight-forwarder authority (MC-FF prefix) and is subject to the same BOC-3 process-agent requirement as motor carriers and brokers.
- See also: Property Broker, MC Authority, BOC-3
G
- GVWR(Gross Vehicle Weight Rating)
- The maximum operating weight of a vehicle as specified by the manufacturer, including the chassis, body, engine, fuel, accessories, driver, passengers, and cargo. The 10,001-lb GVWR threshold separates non-CMV vehicles (state-only oversight) from CMVs (federal FMCSA oversight, BOC-3 required if interstate for-hire).
- See also: CMV, MC Authority
H
- Hazmat(Hazardous Materials · HM Carrier)
- Materials regulated under 49 CFR Parts 100–185 that pose risk in transit (flammables, corrosives, radioactive material, etc.). Hazmat-carrying motor carriers face elevated insurance minimums under 49 CFR Part 387 ($1M–$5M depending on commodity) and CDL drivers need an H endorsement. The BOC-3 designation requirement is unchanged for hazmat carriers.
- See also: CDL, MC Authority, 49 CFR Part 387
- HHG(Household Goods · HHG Carrier)
- A motor carrier authorized to transport household goods (residential moves) for hire across state lines. HHG authority is a distinct FMCSA classification from general-freight motor-carrier authority and triggers additional consumer-protection rules. BOC-3 process-agent designation is required for HHG carriers and HHG brokers alike.
- See also: Common Carrier, MC Authority, Property Broker
- Hours of Service(HOS)
- Federal driving-time limits for commercial motor vehicle drivers under 49 CFR Part 395. Property-carrying drivers may drive up to 11 hours within a 14-hour window, after 10 consecutive off-duty hours; total on-duty time is capped at 60 hours in 7 days or 70 in 8. Tracked via ELD.
- See also: ELD, CDL
- HUT(Highway Use Tax · NY HUT · NM WDT · KY KYU)
- State-level mileage-based taxes on heavy commercial vehicles operating within specific states.

Distinct from federal HVUT (Form 2290).
- See also: Form 2290, IFTA
I
- IFTA(International Fuel Tax Agreement)
- A multi-state agreement that simplifies fuel-tax reporting for commercial vehicles operating across state lines. Carriers register with their base state, file a single quarterly return, and IFTA distributes the revenue to the states where mileage was actually driven. Required for most interstate trucks 26,001+ lbs or 3+ axles.
- See also: IRP, Form 2290
- Interstate Commerce
- Commercial transportation that crosses state lines or originates/terminates in a different state from the carrier's base of operations. Triggers federal FMCSA oversight: USDOT registration, MC authority for for-hire carriers, BOC-3 process-agent designation, BMC-91 insurance, and HOS / ELD compliance. Intrastate-only carriers operate under state oversight without these federal filings.
- See also: FMCSA, USDOT Number, MC Authority
- IRP(International Registration Plan)
- A reciprocal registration agreement among the U.S. states and Canadian provinces that lets a commercial vehicle display a single apportioned license plate while operating in multiple jurisdictions. Fees are split based on miles driven per jurisdiction. Companion to IFTA on the fuel-tax side.
- See also: IFTA, Form 2290
L
- L&I(Licensing & Insurance Bureau)
- The FMCSA bureau that administers operating-authority issuance, insurance filings, and process-agent registrations. L&I publishes the public registry of FMCSA-registered process-agent providers (Form BOC-91 / BOC-91X) at li-public.fmcsa.dot.gov.
- See also: FMCSA L&I System, MC Authority
M
- MC-B(Property Broker Authority · Motor Carrier Broker)
- The FMCSA operating-authority designation for property brokers - entities that arrange transportation for compensation without taking legal possession of freight. MC-B carriers must post a $75,000 BMC-84 surety bond (or BMC-85 trust fund) and file a BOC-3 designation. Distinct from MC-FF (freight forwarder, takes possession) and MC (motor carrier, hauls freight).
- See also: Property Broker, BMC-84, MC Authority
- MCS-150(Biennial Update · Motor Carrier Identification Report)
- The biennial update FMCSA requires from every USDOT-registered carrier to keep contact, address, fleet-size, and operations data current. Filed every 24 months based on the last digit of the USDOT number; failure to file results in a "deactivated" USDOT and triggers automatic suspension of operating authority.
- See also: USDOT Number, MC Authority
- Medical Examiner Certificate(DOT Card · DOT Physical · NRCME)
- A medical certificate that every CDL driver must carry, issued after a physical exam by a healthcare professional listed on the FMCSA's National Registry of Certified Medical Examiners (NRCME). Valid for up to 24 months. Required under 49 CFR Part 391.
- See also: CDL, Hours of Service
N
- New Entrant Safety Audit
- A safety audit the FMCSA conducts on every newly-issued motor carrier within 12 months of authority activation. The audit reviews recordkeeping, driver qualification files, drug & alcohol program compliance, and HOS records. A "fail" suspends operating authority until corrective action is verified.
- See also: MC Authority, CSA Score
O
- OP-1(OP-1 Application · Application for Motor Property Carrier)
- The FMCSA application form a motor carrier files to obtain operating authority. $300 filing fee per authority type. Submitting OP-1 starts a 21-day public protest window, during which BOC-3, insurance (BMC-91), and UCR registration must all land on file for the authority to activate at the close of the window.
- See also: MC Authority, BOC-3, BMC-91, UCR
P
- PIPS(Pre-Intervention Phase Screening)
- An FMCSA process where carriers with elevated CSA scores are flagged for warning letters and follow-up before formal interventions begin. PIPS is the early-warning stage of the SMS / CSA enforcement chain that escalates through warning letters, focused investigations, and ultimately authority revocation if uncorrected.
- See also: CSA Score
- Private Carrier
- A carrier that transports its own goods using its own commercial motor vehicles, not for compensation. Private carriers don't need MC operating authority (since they're not for-hire), don't need BOC-3 designation, but still need a USDOT number and must comply with safety regulations. The BOC-3 requirement applies only to for-hire interstate carriers, brokers, and freight forwarders.
- See also: Common Carrier, USDOT Number
- Process Agent
- A person or company legally authorized to accept service of process - lawsuits, subpoenas, court orders - on behalf of a motor carrier, broker, or freight forwarder. Federal rule under 49 CFR §366 requires every interstate carrier to designate a process agent in every state where they operate or travel through. The BOC-3 form records those designations.

- Property Broker(MC-B · Freight Broker)
- An entity that arranges transportation of property for compensation but does not assume responsibility for the freight itself. Holds FMCSA property-broker authority (MC-B prefix), must post a $75,000 surety bond (BMC-84) or trust fund (BMC-85), and is subject to the same BOC-3 designation requirement as motor carriers.
- See also: BMC-84, BMC-85, MC Authority, BOC-3
- PSP(Pre-employment Screening Program)
- An FMCSA program that lets motor carriers obtain a CDL driver's 5-year crash and 3-year roadside-inspection history from the agency's safety database. Used as an underwriting input during driver hiring. Driver consent is required; results are returned via the PSP portal.
- See also: CDL, CSA Score
S
- SAFER(Safety and Fitness Electronic Records)
- The FMCSA's public-facing carrier-information lookup at safer.fmcsa.dot.gov. Returns operating-authority status, USDOT registration, insurance on file, and basic safety metrics for any registered carrier. Used by brokers, shippers, and load boards to verify a carrier is "AUTHORIZED" before working with them.
- See also: FMCSA, MC Authority, USDOT Number
- SAFETY MEASUREMENT SYSTEM(SMS · CSA SMS)
- The FMCSA's back-end algorithm that scores carrier safety using BASICs (Behavior Analysis and Safety Improvement Categories). SMS scores feed into CSA percentile rankings and trigger interventions when thresholds are crossed. Updated monthly using rolling 24-month inspection and crash data.
- See also: CSA Score, PIPS
- Service of Process
- The formal legal procedure of delivering court documents (lawsuits, subpoenas, court orders) to a defendant. For interstate motor carriers, federal rules require those documents to be delivered to a designated process agent in the state where the carrier operates - which is the entire reason BOC-3 exists.
- See also: Process Agent, BOC-3
T
- Trip Permit(Single-Trip Permit · Temporary Operating Permit)
- A short-term authorization issued by a state allowing a carrier to operate within or through that state without a full annual registration. Trip permits cover specific weights, routes, or commodities and typically last 1-30 days. Common for occasional out-of-IRP-fleet operations; not a substitute for federal MC authority or BOC-3.
- See also: IRP, IFTA, HUT
U
- UCR(Unified Carrier Registration)
- An annual registration and fee paid by every interstate motor carrier, freight broker, leasing company, and freight forwarder under 49 USC §14504a. Fees are tiered by fleet size (six brackets, from 0–2 vehicles to 1,001+) and remitted to a multi-state board that funds state-level safety enforcement. Required to keep operating authority active.
- See also: MC Authority, OP-1, MCS-150
- USDOT Number
- A unique identifier the FMCSA assigns to every commercial motor vehicle operator subject to federal safety regulations. Distinct from MC authority - every interstate carrier needs both, but the USDOT number is the underlying carrier identifier and the MC number is the operating-authority grant. Must be displayed on every commercial motor vehicle in legible type.
