Trucking Glossary

A Motor Carrier number issued by the FMCSA that grants interstate operating authority. You need an MC number before you can legally haul freight across state lines for hire. The application process typically takes 3-4 weeks and costs $300.

A unique identifier assigned by the US Department of Transportation to every commercial vehicle operation in interstate commerce. Unlike the MC number, a USDOT number is required even if you only operate within one state (for vehicles over 10,001 lbs). It must be displayed on both sides of your truck.

A Designation of Process Agents form that lists a legal representative in each state where you operate. Think of it as having someone who can accept legal papers on your behalf. It is required before your operating authority can be activated, and several companies offer blanket BOC-3 coverage for around $30-50.

An annual registration required for all interstate motor carriers, brokers, and freight forwarders. The fee is based on fleet size and must be renewed each year. Failing to register can result in fines during roadside inspections. For a single truck, the fee is typically under $100.

A fuel tax agreement among US states and Canadian provinces that simplifies reporting of fuel use by interstate carriers. Instead of filing separately in each state, you file one quarterly IFTA return that redistributes fuel tax to the states where you actually drove. You get credits for states where you bought more fuel than you burned and owe for states where you burned more than you bought.

A registration reciprocity agreement that allows you to register your truck in one base state while traveling through all member jurisdictions. Your registration fees are apportioned based on the miles you drive in each state. This eliminates the need for separate plates in every state you operate in.

Compliance, Safety, Accountability scores are part of the FMCSA safety measurement system. Scores are tracked across seven BASICs (Behavior Analysis and Safety Improvement Categories) like unsafe driving, HOS compliance, and vehicle maintenance. High scores can trigger FMCSA interventions and make it harder to get loads from safety-conscious brokers.

The Federal Motor Carrier Safety Administration is the federal agency within the DOT that regulates the trucking industry. They issue operating authority, set safety regulations, maintain the SAFER database, and enforce HOS rules. Their website (safer.fmcsa.dot.gov) is where shippers and brokers verify your authority.

Federal regulations that limit how long commercial drivers can operate before taking mandatory rest breaks. The key rules: 11-hour driving limit within a 14-hour window after 10 consecutive hours off duty, plus a mandatory 30-minute break after 8 hours of driving. Violations show up on your CSA score and can lead to being placed out of service.

A federal rule effective since December 2017 requiring most commercial motor vehicle drivers to use Electronic Logging Devices to record their hours of service. The mandate replaced paper logs and applies to drivers who are required to keep records of duty status. Exemptions exist for short-haul drivers, driveaway-towaway operations, and vehicles manufactured before 2000.

An annual federal excise tax (IRS Form 2290) on highway motor vehicles with a taxable gross weight of 55,000 pounds or more. The tax is $100 for vehicles 55,000 lbs, increasing up to $550 for vehicles at 75,000 lbs and above. You must file by August 31 each year and keep your stamped Schedule 1 in the truck as proof of payment.

An FMCSA online system that allows motor carriers and drivers to request a review (challenge) of federal and state data, such as crash reports and inspection results. If you received an unfair inspection violation, DataQs is how you formally dispute it. Successful challenges can improve your CSA score.

A review conducted by the FMCSA within the first 18 months of a new carrier receiving operating authority. The audit examines your safety management practices, driver qualifications, vehicle maintenance records, and HOS compliance. Failing a safety audit can result in your authority being revoked.

The official FMCSA authorization to operate as a for-hire carrier, broker, or freight forwarder in interstate commerce. Getting your own authority (as opposed to leasing on to another carrier) means you can book your own loads and negotiate your own rates, but you also take on the responsibilities of insurance, compliance, and recordkeeping.

An MC number with broker authorization from the FMCSA, allowing an entity to arrange transportation of freight without actually owning trucks. Brokers must maintain a $75,000 surety bond or trust fund (BMC-84 or BMC-85). This is different from carrier authority, which allows you to physically haul freight.

A $75,000 surety bond (BMC-84) or trust fund (BMC-85) required by the FMCSA for all licensed freight brokers and freight forwarders. The bond protects carriers and shippers if the broker fails to pay. Annual premiums vary by credit score, typically ranging from $900 to $10,000 per year.

The Motor Carrier Identification Report that must be filed with FMCSA when you first apply for a USDOT number and updated biennially (every two years) based on your USDOT number. It contains operational information like fleet size, cargo types, and miles driven. Failure to update it can result in deactivation of your USDOT number.

Selling your freight invoices to a factoring company at a small discount in exchange for immediate payment, typically within 24 hours. Instead of waiting 30-90 days for a broker to pay, you get cash flow right away. Factoring rates usually range from 1.5% to 5% of the invoice amount.

A type of factoring where you (the carrier) are responsible if the broker or shipper does not pay the invoice. If the debtor defaults, the factoring company charges the amount back to you. Recourse factoring has lower fees (typically 1-3%) because the carrier bears the credit risk.

A type of factoring where the factoring company assumes the risk if the broker or shipper fails to pay due to insolvency or bankruptcy. If the debtor cannot pay, you do not owe the money back. Rates are higher (typically 3-5%) to compensate for the added risk the factor takes on. Note that non-recourse usually only covers credit risk, not disputes.

A service offered by some brokers and load boards where carriers can get paid faster (often within 2-5 business days) in exchange for a small fee, typically 1-3% of the load amount. Unlike factoring, quick pay is offered directly by the party that owes you, cutting out the middleman.

Compensation for time spent waiting at a shipper or receiver beyond the agreed free time (usually 1-2 hours). Industry standard detention rates range from $25 to $75 per hour, though many carriers negotiate higher. Getting detention pay consistently requires documenting your arrival/departure times and having it specified in your rate confirmation.

A fee charged by a third-party labor service at a warehouse or distribution center to load or unload your trailer. Lumper fees typically range from $150 to $500+ depending on the load. Many brokers will reimburse lumper fees, but you should confirm this before accepting a load and keep your receipts.

A fee paid to a carrier when they arrive at a shipper and the load is cancelled, not ready, or significantly different from what was agreed upon. TONU fees typically range from $100 to $350 and are meant to compensate for the wasted trip. Not all brokers honor TONU, so make sure it is in your rate confirmation.

Additional fees beyond the standard line-haul rate that cover extra services like liftgate use, inside delivery, residential delivery, detention, or driver-assist unloading. Accessorials should be documented in the rate confirmation before you pick up. They can add $50 to $500+ per load depending on the service required.

A daily allowance that covers meals and incidental expenses while an over-the-road driver is away from their tax home. The IRS sets the per diem rate (currently $69/day in the continental US) and allows truckers to deduct 80% of it. This is one of the biggest tax deductions available to owner-operators.

Driving empty (without a paying load) to reach a pickup location or return home. Deadhead miles generate zero revenue but still cost you fuel, maintenance, and wear. Keeping your deadhead percentage below 10-15% is crucial for profitability. Dispatchers and load boards help minimize deadhead by finding backhaul loads.

Your gross earnings divided by total miles driven (loaded + empty). RPM is the most important metric for comparing loads. A $3,000 load over 1,200 miles is $2.50/mile, but if you deadhead 200 miles to pick it up, your effective RPM drops to $2.14/mile. Always calculate RPM on all miles, not just loaded miles.

Your total operating costs divided by total miles driven. Knowing your CPM is essential for determining which loads are profitable. Average owner-operator CPM ranges from $1.20 to $1.85+ depending on equipment, insurance costs, and fuel prices. Any load paying less than your CPM loses money.

The total amount of money you earn from hauling freight before any expenses are deducted. This includes line-haul pay, fuel surcharges, accessorials, detention pay, and any other load-related income. Gross revenue is not profit and can be misleading without understanding your costs.

Your gross revenue minus all operating expenses including fuel, insurance, truck payment, maintenance, permits, dispatch fees, and factoring fees. Net revenue is what you actually keep and is a far more meaningful number than gross. A truck grossing $250K but netting only $50K is less profitable than one grossing $180K and netting $70K.

An additional charge added to the line-haul rate that fluctuates with diesel prices. The surcharge is meant to offset fuel cost volatility so carriers and brokers do not have to constantly renegotiate base rates. Most surcharge schedules are tied to the DOE national average diesel price and recalculate weekly.

The legally binding document (also called a rate con or load confirmation) that details the terms of a load: pickup/delivery locations, dates, rate, commodity, weight, and any special instructions or accessorial agreements. Never move a load without a signed rate confirmation, as it is your proof of the agreed-upon terms.

A legal document issued by the shipper that serves as a receipt of goods, a contract of carriage, and a document of title. The BOL describes the freight, its destination, and the terms of transport. Always check the BOL at pickup to verify the commodity, count, and condition match what you were told.

A signed document (usually a signed BOL or delivery receipt) confirming that freight was delivered to the consignee. The POD is essential for getting paid because it proves you completed the job. Most factoring companies and brokers require a clean POD with no damage notations before they release payment.

A set of documents you submit to a broker to get set up in their system before hauling loads. A typical carrier packet includes your MC authority, insurance certificate, W-9, signed broker-carrier agreement, and a notice of assignment if you use a factoring company. Having a clean, complete packet ready speeds up onboarding.

A freight lane is a specific origin-to-destination route that freight regularly moves on. For example, Dallas to Atlanta is a lane. Some lanes are more profitable than others depending on supply and demand. Dedicated lanes provide consistent freight on the same route, offering predictable revenue.

A load picked up for the return trip after delivering your primary (head haul) load, preventing an empty drive back. Backhaul rates are often lower than head haul rates because the carrier needs to get back anyway. Even a lower-paying backhaul is better than deadheading empty.

The primary, outbound load on a route, typically the higher-paying leg of a round trip. Head haul lanes move freight from production areas to consumption areas (e.g., produce from California to the East Coast). Rates on head haul lanes are usually 20-40% higher than the corresponding backhaul direction.

A system where two or more drivers each handle a portion of a long-haul route, passing the loaded trailer from one driver to the next at relay points. Relays allow freight to move coast-to-coast faster than a single driver while keeping everyone within HOS limits. Some carriers use relay networks as an alternative to team driving.

A loading method where the driver drops a loaded or empty trailer at a facility and hooks to a different pre-loaded trailer, avoiding the wait time of live loading. Drop and hook can save hours of detention time per load. Carriers with drop trailer programs at high-volume shippers gain a significant efficiency advantage.

When a driver must wait at the dock while their trailer is loaded or unloaded, as opposed to drop and hook. Live loads can take 1-6+ hours depending on the facility and commodity. Excessive wait times at live load facilities are the main reason detention pay exists.

An arrangement where two qualified drivers share a truck, taking turns driving and sleeping so the truck can run nearly 24 hours a day. Teams can cover up to 1,000+ miles per day compared to 500-600 for a solo driver. Team loads typically pay a premium because shippers value the faster transit time.

A truck driver who owns or leases their own truck and operates as an independent business. Owner-operators can run under their own authority (booking loads directly) or lease on to a carrier. While the earning potential is higher than company driving, owner-operators bear all costs: fuel, insurance, maintenance, permits, and taxes.

A program offered by some carriers where a driver makes weekly payments toward owning a truck while hauling loads for that carrier. Lease purchase agreements vary widely. Some are legitimate paths to ownership; others have unfavorable terms that make it nearly impossible to build equity. Always have the contract reviewed by a trucking attorney before signing.

The most common trailer type in trucking, an enclosed box trailer used for non-temperature-sensitive freight. Dry vans are versatile, handling everything from palletized goods and retail products to packaged food and consumer electronics. They account for roughly 60% of all truckload freight in the US.

A temperature-controlled trailer with a built-in refrigeration unit used to haul perishable goods like produce, frozen foods, dairy, and pharmaceuticals. Reefer loads typically pay 15-30% more than dry van but come with higher operating costs (fuel for the reefer unit, maintenance, and potential cargo claims). Drivers must monitor temperature throughout transit.

An open trailer without sides or a roof, used for hauling oversized, heavy, or oddly shaped freight like steel, lumber, machinery, and building materials. Flatbed loads require tarping and securement, which is physically demanding and time-consuming. Flatbed rates are typically the highest in dry freight because of the skill and labor involved.

A flatbed trailer with a lower deck section that allows hauling taller freight (up to about 10 feet) without needing oversize permits. The upper deck sits at standard flatbed height while the lower deck drops down, creating a step. Step decks are popular for hauling tall machinery, vehicles, and building materials that would exceed height limits on a standard flatbed.

A trucking niche using a heavy-duty pickup truck (typically a Class 3-5 dually) pulling a flatbed gooseneck trailer, usually 30-40 feet long. Hotshot carriers often haul time-sensitive, smaller loads like oilfield equipment, machinery parts, and construction materials. Lower startup costs make it a popular entry point into trucking, but competition is fierce and rates can be tight.

A flatbed trailer with a rolling tarp system (similar to a covered wagon) that can be retracted to load from the sides or top. Conestoga trailers combine the freight protection of an enclosed trailer with the loading flexibility of a flatbed. They command premium rates because they protect cargo from weather while eliminating manual tarping.

A specialized heavy-haul trailer with a very low deck height (18-24 inches from the ground), designed for hauling extremely heavy or tall equipment like excavators, bulldozers, and industrial machinery. Lowboys can typically carry 40,000-80,000+ pounds. Most lowboy loads require oversize permits and escort vehicles.

A trucking arrangement where a carrier provides only the tractor (power unit) and driver, while the shipper or broker supplies the trailer. Power only loads can be attractive because they eliminate the cost of owning or leasing a trailer. Many Amazon and Walmart relay programs operate on a power only basis.

Driving a tractor without a trailer attached. Bobtailing is generally avoided because the truck handles poorly without weight on the rear axle (especially in wet or icy conditions), it earns no revenue, and insurance may have limited coverage. It is the less desirable cousin of deadheading, which at least involves pulling an empty trailer.

A cylindrical trailer designed to transport liquid or gaseous cargo such as fuel, chemicals, milk, or water. Tanker drivers face unique challenges including liquid surge (sloshing), specialized loading/unloading procedures, and hazmat endorsement requirements for many loads. Tanker rates reflect the specialized skill and endorsements required.

A shipping method that uses standardized containers (typically 20 or 53 feet) that can transfer between trucks, trains, and ships without unloading the cargo. In trucking, intermodal usually means a driver picks up or delivers a container at a rail yard or port. Intermodal is often cheaper than pure truckload for long-haul moves over 1,000 miles.

A device that connects to a truck's engine and automatically records driving time and hours of service data. ELDs replaced paper logbooks for most commercial drivers under the 2017 ELD Mandate. Popular brands include KeepTruckin (now Motive), Samsara, and Geotab. The device must be registered with FMCSA.

Real-time location tracking technology used to monitor truck positions, optimize routes, and provide ETAs to brokers and shippers. Many ELD devices include GPS tracking as a built-in feature. Brokers increasingly require real-time tracking capability as a condition of hauling their loads.

Technology that combines GPS, vehicle diagnostics, and wireless communication to monitor fleet performance. Telematics systems track fuel consumption, idle time, hard braking, speed, engine fault codes, and driver behavior. This data helps owner-operators and fleets reduce costs and improve safety scores.

A camera system mounted in or on a truck that continuously records forward-facing (and sometimes driver-facing) video. Dashcams protect drivers from false accident claims, document unsafe driver behavior for coaching, and can reduce insurance premiums by 10-15%. Many fleets now require them, and some ELD providers include integrated dashcam features.

An online marketplace where brokers and shippers post available freight loads and carriers search for loads to haul. Major load boards include DAT, Truckstop.com (now Truckstop), and Amazon Relay. Load boards charge subscription fees ($40-$150+/month) and are an essential tool for owner-operators who do not have a dispatcher or consistent contract freight.

Software used by shippers, brokers, and carriers to plan, execute, and optimize freight movements. A TMS handles load planning, carrier selection, route optimization, shipment tracking, and freight audit/payment. For small carriers, simpler TMS tools help with dispatch management and invoicing.

A written or electronic report that drivers must complete at the end of each driving day, documenting the condition of their vehicle and any defects found during pre-trip or post-trip inspections. If defects are found, the motor carrier must repair them before the vehicle can be dispatched again. Most ELD apps include a digital DVIR feature.

A thorough vehicle inspection that drivers are required to perform before operating their truck each day. The inspection covers tires, brakes, lights, mirrors, fluid levels, coupling devices, and safety equipment. Pre-trip inspections are not optional since they are mandated by FMCSA regulations, and skipping them is a common citation during roadside inspections.

A vehicle inspection performed at the end of the driving day to identify any defects or issues that developed during the trip. While less commonly cited than pre-trip violations, post-trip inspections are equally important for catching brake wear, tire damage, or light failures before they become safety hazards or roadside violations.

A special license required to operate commercial motor vehicles. CDLs come in three classes: Class A (combination vehicles over 26,001 lbs), Class B (single vehicles over 26,001 lbs), and Class C (vehicles carrying hazmat or 16+ passengers). Additional endorsements include T (doubles/triples), P (passenger), N (tanker), H (hazmat), and X (tanker + hazmat).

A roadside safety inspection conducted by state or federal DOT officers at weigh stations, inspection sites, or during traffic stops. There are six inspection levels, from Level I (full 37-step inspection of driver and vehicle) to Level VI (enhanced inspection for radioactive shipments). Violations are recorded in the FMCSA database and affect your CSA score.

An order issued by a DOT inspector that prohibits a driver from driving or a vehicle from being operated until specific safety violations are corrected. OOS violations are serious and include things like brake defects, tire tread below minimum depth, HOS violations, or a suspended CDL. OOS rates are a key component of CSA scores.

A DOT safety check conducted at the roadside, weigh station, or inspection facility. Officers check driver credentials (CDL, medical card, HOS logs), vehicle condition (brakes, tires, lights, securement), and cargo (weight, hazmat compliance). Results are uploaded to FMCSA and impact your safety record. Keeping a clean, well-maintained truck significantly reduces the chance of violations.

The practice of selling your unpaid freight invoices to a third-party factoring company in exchange for immediate cash, typically within 24 hours. This solves the cash flow gap caused by brokers paying on 30-90 day terms. Factoring rates range from 1.5% to 5% per invoice, and most factoring companies also provide free credit checks on brokers before you haul for them.

A secure federal database launched in January 2020 that tracks commercial driver drug and alcohol testing violations. Employers must query the Clearinghouse before hiring a driver and annually thereafter. Drivers with unresolved violations cannot perform safety-sensitive functions until they complete a return-to-duty process. Registration is free for drivers at clearinghouse.fmcsa.dot.gov.

Liability insurance that covers a tractor when it is being driven without a trailer attached, such as commuting between your home and a terminal or driving to pick up a trailer. Most primary auto liability policies exclude bobtail situations, leaving a dangerous coverage gap. Bobtail insurance typically costs $300-$600 per year and is essential for any owner-operator who does not always have a trailer hooked.

Insurance that covers the value of the freight you are hauling in case of damage, theft, or loss during transit. FMCSA requires a minimum of $100,000 in cargo coverage for general freight carriers, but most brokers require $100,000-$250,000. Cargo insurance premiums typically run $400-$1,800 per year depending on commodity type, coverage limits, and deductible.

An illegal practice where a broker re-brokers a load to another broker without the shipper's knowledge or consent, adding an undisclosed middleman to the transaction. Double brokering creates serious payment risks because the carrier may never get paid if the second broker disappears with the money. Red flags include rate confirmations from a company different than who posted the load, unusually high rates, and requests to use a different factoring company.

A Transportation Worker Identification Credential issued by the TSA that grants unescorted access to secure areas of maritime ports and vessels. The TWIC card requires a background check and costs approximately $125 with a 5-year validity period. Drivers who regularly pick up or deliver at port facilities (drayage, intermodal) need a TWIC card to avoid delays and escort fees that can run $50-$150 per visit.

The movement of a commercial motor vehicle for personal use while off duty, such as driving to a restaurant, hotel, or safe parking location. Under FMCSA guidance, personal conveyance does not count against your 11-hour driving or 14-hour on-duty limits. However, it cannot be used to advance toward a shipper or receiver, and the driver must be relieved of all dispatch responsibilities during the move.

The current market price for moving a load on a one-time basis, as opposed to a contracted rate locked in for months or a year. Spot rates fluctuate daily based on supply and demand, fuel prices, weather, and seasonal freight patterns. In a tight market, spot rates can be 30-50% higher than contract rates, but in a soft market they can drop well below contract levels. Most load board freight is priced at spot rates.

Short-distance hauling of shipping containers or trailers between ports, rail yards, and nearby warehouses or distribution centers, typically within a 50-mile radius. Drayage drivers often make multiple short trips per day rather than one long haul. The work involves significant wait times at port terminals, and having a TWIC card is usually required. Drayage rates are typically per-move rather than per-mile.

A shipping method for freight that does not require a full trailer, typically between 150 and 15,000 pounds. LTL carriers consolidate multiple shippers' freight onto a single trailer, with each shipper paying only for the space they use. Unlike full truckload (FTL), LTL freight moves through a network of terminals with multiple handling points, which means longer transit times but lower costs for smaller shipments.

A company that manages logistics and supply chain operations on behalf of shippers, including transportation, warehousing, and distribution. 3PLs act as intermediaries between shippers and carriers, often managing large volumes of freight. Major 3PLs include C.H. Robinson, XPO Logistics, and Echo Global Logistics. For owner-operators, 3PLs can be a reliable source of freight but often pay lower rates than going direct to shippers.

A motor carrier that shuts down or abandons its USDOT number after receiving poor safety ratings or being placed out of service, then reopens under a new name, USDOT number, and MC number to evade enforcement. The FMCSA actively investigates chameleon carriers under its reincarnated carrier program. Brokers should check carrier history carefully, and drivers should avoid working for carriers that have suspiciously new authority with experienced equipment.
