Accessorial Charges
Fees charged beyond the base line haul rate for services not covered in the original rate agreement. Common accessorials include detention, layover, TONU, lumper fees, and fuel surcharges. All accessorial charges must be documented and ideally pre-negotiated in the rate confirmation.
Bill of Lading (BOL)
49 CFR Part 373A legally binding document issued by the shipper that serves as a receipt for cargo, a contract of carriage, and a document of title. The BOL specifies the freight description, weight, origin, destination, and handling requirements. Every load requires a BOL — it is the primary document for cargo claims and proof of delivery.
Cargo Insurance
49 CFR Part 387Insurance coverage that protects the value of freight in the carrier's care, custody, and control. FMCSA requires motor carriers hauling general freight to carry minimum cargo insurance of $5,000 per vehicle or $10,000 per occurrence. Higher limits are required for certain commodity types.
Carrier Packet
A collection of documents required by brokers and shippers before a carrier can haul freight. A standard carrier packet includes the operating authority certificate, certificate of insurance (COI), W-9, and signed carrier setup agreement. Having a complete, current carrier packet is required to book loads.
Conditional Rating
49 CFR Part 385A safety fitness rating issued by FMCSA indicating a carrier has critical safety deficiencies that must be corrected. Carriers with a Conditional rating can continue operating but are subject to increased scrutiny. Brokers and shippers may decline to use Conditional-rated carriers.
Contract Rate
A pre-negotiated, fixed freight rate agreed upon between a shipper and carrier for a defined lane or volume of freight over a specified contract period — typically 12 months. Contract rates provide revenue predictability and are generally preferred over spot rates for established operations.
CSA Score (BASICs)
49 CFR Part 385The Compliance, Safety, Accountability measurement system used by FMCSA to assess motor carrier safety performance across seven Behavior Analysis and Safety Improvement Categories (BASICs): Unsafe Driving, Hours-of-Service Compliance, Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, Hazardous Materials Compliance, and Crash Indicator. Elevated BASIC percentiles trigger FMCSA intervention.
DAC Report
A Driver Applicant Checking Service report maintained by HireRight that contains a commercial driver's employment history, termination reasons, accident history, and drug/alcohol test results as reported by previous motor carrier employers. Most carriers check the DAC report during the driver hiring process.
Deadhead Miles
Miles driven with an empty trailer — typically from a delivery point to the next pickup location. Deadhead miles generate operating costs (fuel, driver wages) with zero revenue. Minimizing deadhead through efficient lane management is one of the most direct profitability levers available to carriers and dispatchers.
Detention
A charge assessed when a carrier's driver is delayed at a shipper or receiver beyond the free time specified in the rate confirmation — typically two hours. Detention must be documented with driver arrival/departure timestamps and communicated to the broker while it is occurring. Undocumented detention is rarely paid.
Dispatcher
An operations professional who coordinates freight movement between brokers and carriers. Dispatchers source loads, negotiate rates, manage paperwork, communicate with drivers, and handle load issues. Third-party dispatchers working for hire may be subject to broker registration requirements under FMCSA interpretations.
DOT Number
49 CFR Part 390A unique identifier issued by the FMCSA to commercial motor vehicles operating in interstate commerce above defined weight thresholds. The DOT number is used to monitor a carrier's safety compliance, inspection history, and crash data. All for-hire carriers must display their DOT number on their equipment.
Double Brokering
49 CFR Part 371The illegal practice of a freight broker re-brokering a load to another broker without the original shipper's consent. Double brokering creates serious liability exposure, payment chain complexity, and cargo claim risk. It is a violation of FMCSA regulations and most broker-carrier agreements.
Drayage
The short-distance transport of intermodal shipping containers — typically between a port, rail terminal, or warehouse and a local distribution point. Drayage is a specialized segment of trucking with distinct equipment requirements (chassis, ISO containers) and port-specific operating procedures.
Driver Qualification File (DQF)
49 CFR Part 391A mandatory file maintained by motor carriers for each driver that documents compliance with FMCSA driver qualification standards. Required contents include the employment application, motor vehicle record (MVR), medical examiner certificate, road test certificate, and annual review of driving record. DQFs must be retained for three years after employment ends.
Drop and Hook
A freight pickup or delivery method where a driver drops a loaded or empty trailer at a facility and hooks a different trailer without waiting for loading or unloading. Drop and hook operations improve driver efficiency by eliminating dock wait time and are common in high-volume shipper relationships.
ELD (Electronic Logging Device)
49 CFR Part 395 Subpart BA federally mandated device that automatically records a driver's hours of service data by connecting to the vehicle's engine. ELDs replaced paper logbooks for most commercial drivers in December 2017. The ELD must meet FMCSA technical specifications and be registered on the FMCSA ELD registry.
Factoring
A financial service where a carrier sells its freight invoices to a factoring company at a discount in exchange for immediate payment — typically same-day or next-day. Factoring eliminates the 30-60 day wait for broker payment. Factoring fees typically range from 1.5% to 5% per invoice depending on recourse terms and volume.
Fleet Owner
A motor carrier that owns and operates multiple commercial trucks, either through company drivers or owner-operators leased to the fleet. Fleet owners are responsible for maintaining operating authority, compliance systems, driver qualification files, and equipment for all vehicles in the fleet.
FMCSA
49 CFR Parts 300–399The Federal Motor Carrier Safety Administration — the U.S. Department of Transportation agency responsible for regulating and enforcing safety standards for commercial motor vehicles in interstate commerce. FMCSA issues operating authority, sets Hours of Service rules, administers the CDL program, and enforces safety compliance through inspections and audits.
Freight Broker Bond
49 CFR Part 387 Subpart CA $75,000 surety bond (BMC-84) or equivalent trust fund required by FMCSA as a condition of broker authority. The bond protects carriers and shippers against broker non-payment. The bond must be maintained continuously — any lapse results in automatic revocation of broker authority.
Freight Forwarder
49 CFR Part 371An entity that assembles and consolidates shipments and, acting as a principal, assumes responsibility for the transportation of cargo from point of receipt to destination. Freight forwarders require separate FMCSA authority and are distinct from brokers — they take legal responsibility for the freight, not just arrange its movement.
Fuel Surcharge
An additional per-mile or percentage charge added to the base freight rate to offset fluctuating diesel fuel costs. Fuel surcharges are typically calculated using a fuel surcharge table indexed to the Department of Energy's weekly diesel fuel price report. Most contract rates include a fuel surcharge matrix.
General Liability
Insurance coverage that protects a motor carrier, broker, or freight business against third-party claims for bodily injury, property damage, and personal/advertising injury arising from business operations. General liability is distinct from cargo insurance and auto liability — all three are typically required for commercial transportation businesses.
Hazmat Placard
49 CFR Part 172 Subpart FA color-coded diamond-shaped sign required to be displayed on vehicles transporting hazardous materials in regulated quantities. Specific placards correspond to the DOT hazard class of the material being transported. Improper placarding is a serious FMCSA violation with significant civil penalties.
Hours of Service (HOS)
49 CFR Part 395Federal regulations limiting the maximum hours a commercial driver may drive and be on duty before mandatory rest periods. Key limits include: 11-hour driving limit after 10 consecutive off-duty hours, 14-hour on-duty window, 60/70-hour weekly limit, and 30-minute break requirement. HOS violations are a top roadside inspection citation and CSA BASIC contributor.
IFTA
The International Fuel Tax Agreement — a cooperative agreement among the 48 contiguous U.S. states and 10 Canadian provinces that simplifies fuel tax reporting for carriers operating across jurisdictions. Carriers with qualified motor vehicles must file quarterly IFTA reports and display IFTA decals on their equipment.
Intermodal
Freight transportation using two or more modes of transport — typically combining rail and truck — without handling the freight itself when changing modes. Intermodal shipping uses standardized ISO containers that can transfer between ship, rail, and truck. Intermodal carriers often specialize in drayage operations at rail ramps and ports.
IRP
The International Registration Plan — a reciprocal agreement for registration of commercial vehicles operating in two or more member jurisdictions. IRP allows carriers to obtain a single apportioned license plate recognized in all member states and provinces, with registration fees distributed based on miles traveled in each jurisdiction.
Load Board
A digital marketplace platform where freight brokers post available loads and carriers search for freight matching their equipment and lane preferences. Major load boards include DAT and Truckstop.com. Load boards are the primary matching mechanism between available capacity and available freight in the spot market.
Lumper
A third-party labor service used to load or unload freight at a warehouse or distribution center. Lumper fees are an accessorial charge that should be addressed in the rate confirmation before dispatch. Drivers are not obligated to perform lumper work unless agreed to in writing.
Owner-Operator
A commercial truck driver who owns and operates their own commercial motor vehicle, either independently with their own authority or leased to a larger motor carrier under a lease agreement. Owner-operators are responsible for their own IFTA, IRP, insurance, and equipment maintenance whether operating under their own or a carrier's authority.
Pre-Trip Inspection
49 CFR Part 396.13A mandatory systematic inspection of a commercial motor vehicle that drivers must complete before each trip. Drivers must report any defects in writing. The inspection covers brakes, lights, tires, coupling devices, steering, and emergency equipment. Failed or skipped pre-trip inspections are a recordable FMCSA violation.
Rate Confirmation
A legally binding document issued by a freight broker confirming the agreed-upon freight rate, load details, pickup and delivery requirements, and accessorial terms. The rate confirmation must be reviewed and signed by the carrier or dispatcher before loading. It is the primary reference document for payment disputes.
Safety Rating
49 CFR Part 385The official safety fitness determination assigned to a motor carrier by FMCSA following a compliance review. There are three ratings: Satisfactory (meets minimum standards), Conditional (has safety deficiencies), and Unsatisfactory (fails to meet minimum standards). An Unsatisfactory rating prohibits interstate operation.
Satisfactory Rating
49 CFR Part 385The highest FMCSA safety fitness rating, indicating a motor carrier has adequate safety management controls to meet the minimum safety fitness standards. Carriers with a Satisfactory rating are generally treated as compliant by shippers and brokers. A Satisfactory rating can still be downgraded if safety performance deteriorates.
Spot Rate
A one-time freight rate negotiated for a single load based on current market supply and demand conditions. Spot rates are found on load boards and fluctuate with seasonal demand, fuel prices, and regional capacity. Spot rate volatility is the primary reason experienced carriers pursue contract freight relationships.
TONU (Truck Order Not Used)
An accessorial charge assessed when a carrier is dispatched and en route or positioned at the shipper, but the load is canceled. TONU compensation varies by negotiation but commonly covers 1–2 hours of driver time plus fuel costs. TONU must be pre-negotiated and documented in the rate confirmation to be enforceable.
UCR (Unified Carrier Registration)
49 CFR Part 367A federally mandated annual registration program for motor carriers, freight brokers, freight forwarders, and leasing companies that operate in interstate commerce. UCR fees are based on fleet size and are distributed among participating states. UCR must be renewed annually and is enforced at roadside inspections.
Unsatisfactory Rating
49 CFR Part 385The lowest FMCSA safety fitness rating, indicating a motor carrier fails to meet the minimum safety fitness standards. An Unsatisfactory rating prohibits the carrier from operating in interstate commerce until the safety deficiencies are corrected and the rating is upgraded. Most shippers and brokers will not tender freight to an Unsatisfactory-rated carrier.
