Auto Shipping Glossary — Every Term Explained

**Accessorial Charges** — Extra fees beyond the base transport rate for additional services. In auto transport, common accessorials include residential pickup/delivery surcharges, inoperable vehicle fees ($150-$300), and expedited service premiums. In freight shipping, accessorials include liftgate service ($75-$150), inside delivery, and appointment scheduling. Always ask about potential accessorials before booking so there are no surprises.

**Auto Carrier** — The truck-and-trailer combination used to haul multiple vehicles. A standard open auto carrier hauls 7-9 vehicles on a multi-level trailer. Enclosed carriers haul 2-6 vehicles in a fully enclosed trailer. The term also refers to the company that owns and operates the truck. Don't confuse "carrier" with "broker" -- the carrier physically moves your vehicle; the broker coordinates the shipment.

**Backhaul** — A carrier's return trip after delivering vehicles on a primary corridor. For example, a carrier running full loads from California to the East Coast needs loads heading back west. Because the carrier needs to return regardless, they'll often accept westbound shipments at a discount -- 10-20% less than the primary direction. If your shipment happens to align with a carrier's backhaul direction, you save money. Our AI marketplace identifies backhaul opportunities automatically.

**Bill of Lading (BOL)** — The most important document in auto transport. At pickup, the driver inspects your vehicle and records its condition on the BOL, including a vehicle diagram noting every scratch, dent, and imperfection. Both you and the driver sign it. At delivery, you compare the vehicle's condition to the pickup BOL. Any new damage is noted on the delivery BOL before you sign. This document is the legal baseline for damage claims. Treat it seriously.

**Binding Quote** — A price guarantee. When a company provides a binding quote, the price is locked in and cannot change, regardless of market fluctuations or carrier availability. This is what you want. A non-binding quote (also called an estimate) can be changed at any time for any reason. At American Auto Shipping, every quote is binding.

**Broker** — A company licensed by the FMCSA to arrange vehicle transportation by connecting shippers (you) with carriers (the truck companies). Brokers don't own trucks -- they coordinate logistics. About 85% of all auto shipments go through brokers because no single carrier runs every route. The key is working with a licensed, reputable broker with binding pricing and verified carriers.

**Cargo Insurance** — Insurance carried by the carrier that covers damage to vehicles in their care during transport. Most auto transport carriers carry cargo insurance ranging from $100,000 to $1,000,000 per occurrence, with per-vehicle limits that vary. This is separate from the carrier's liability insurance. For high-value vehicles, verify the carrier's cargo insurance limit covers your vehicle's full value.

**Car Hauler** — Another term for an auto carrier -- the truck-and-trailer rig that transports vehicles. Open car haulers are the most common, carrying 7-9 vehicles on exposed decks. Enclosed car haulers carry 2-6 vehicles in a protected trailer.

**Central Dispatch** — The largest load board in the auto transport industry. Carriers and brokers post available loads and truck capacity. When a broker lists your shipment, carriers on Central Dispatch can see it and bid on it. Our AI marketplace functions similarly but with additional carrier verification and binding pricing.

**COD (Cash on Delivery)** — The standard payment arrangement in auto transport. You pay a deposit to the broker at booking, and the remaining balance is paid directly to the carrier at delivery. Payment methods for the carrier portion typically include cashier's check, money order, or cash.

**Coloading** — Combining multiple shipments on a single carrier to fill available space. If a carrier has two empty spots on a 9-car hauler, filling those spots with coloaded vehicles is more efficient and cost-effective than running partially empty. Coloading benefits shippers through lower per-vehicle costs.

**Condition Report** — The section of the Bill of Lading where the driver documents the vehicle's current condition using a diagram and written notes. The pickup condition report is your baseline; the delivery condition report shows whether anything changed during transport.

**Deadhead** — When a carrier drives empty (no vehicles loaded) to reach a pickup location. Deadheading costs the carrier fuel and time without generating revenue, so carriers try to minimize it. If your vehicle requires a carrier to deadhead 100+ miles off their regular route, expect higher pricing. Pickups in major metro areas on high-traffic corridors have minimal deadhead, which is why they're cheaper and faster.

**Delivery Window** — The estimated timeframe for when your vehicle will arrive at the destination. Carriers provide a delivery window (not an exact time) because multi-stop routes are subject to variables: weather, traffic, earlier pickups/deliveries running long. The carrier will narrow the window to a specific day and call you 12-24 hours before arrival.

**Dispatch** — The process of assigning a carrier to your shipment. Once you book, the broker dispatches your load to a carrier whose route, availability, and equipment match your needs. Dispatch also refers to the carrier's operational headquarters that manages driver assignments, routes, and schedules.

**Door-to-Door Service** — The carrier picks up your vehicle at your specified location and delivers it to your specified destination, as close to each address as the truck can safely access. This is the standard service level. The alternative is terminal-to-terminal, where you drop off and pick up at the carrier's facility. Door-to-door costs slightly more but is far more convenient.

**Driveaway** — A transport method where a professional driver physically drives your vehicle from origin to destination instead of hauling it on a trailer. Driveaway is most common for RVs and motorhomes that are too large or heavy for standard carriers. The vehicle accumulates mileage during driveaway, and fuel costs are a significant factor.

**ELD (Electronic Logging Device)** — A federally mandated device installed in commercial trucks that automatically records driving time, helping ensure drivers comply with Hours of Service regulations. ELDs replaced paper logbooks in 2017 and make it virtually impossible for drivers to exceed their legal driving hours. This is a safety regulation that protects everyone on the road.

**Enclosed Transport** — Vehicle transport using a fully enclosed trailer with walls, roof, and floor. Protects vehicles from weather, road debris, UV exposure, and visibility. Used for high-value, classic, exotic, and show vehicles. Costs 40-60% more than open transport but offers the highest level of protection. Enclosed carriers typically haul 2-6 vehicles.

**Estimated Time of Arrival (ETA)** — The projected date and time your vehicle will be delivered. ETAs are estimates, not guarantees, because multi-stop routes are subject to weather, traffic, and scheduling variables. Carriers update ETAs during transit as conditions evolve.

**Expedited Shipping** — Priority service that speeds up the pickup window and transit time. Expedited auto transport typically means pickup within 24-48 hours versus the standard 1-5 business day window. Costs 30-50% more than standard service. Recommended for urgent relocations, military PCS moves, and time-sensitive vehicle purchases.

**First Available Date (FAD)** — The earliest date you're ready for the carrier to pick up your vehicle. This is the starting point for your pickup window. The carrier won't arrive before your FAD but will aim to pick up within 1-5 business days after it. Providing a flexible FAD gives carriers more routing options, which often results in faster matching and lower pricing.

**Flatbed Trailer** — A flat, open trailer without sides or a roof, used for oversized vehicles, heavy equipment, and non-standard cargo. In auto transport, flatbed is used for vehicles that don't fit on a standard multi-car hauler -- lifted trucks over 7 feet tall, heavy equipment, boats on trailers, and oversized vehicles.

**FMCSA (Federal Motor Carrier Safety Administration)** — The federal agency that regulates the trucking and auto transport industries. Every auto transport broker and carrier must register with the FMCSA and maintain an active operating authority (MC number). The FMCSA enforces safety regulations, insurance requirements, and licensing standards. You can verify any company's license status at FMCSA.gov or safer.fmcsa.dot.gov. If a company isn't registered, they're operating illegally.

**GVWR (Gross Vehicle Weight Rating)** — The maximum total weight a vehicle is designed to carry, including the vehicle itself, passengers, cargo, and fluids. In auto transport, GVWR matters for carriers managing weight limits across multiple vehicles on a single trailer. Federal bridge law limits total truck-plus-cargo weight to 80,000 lbs on Interstate highways.

**Guaranteed Pickup** — A premium service where the carrier commits to picking up your vehicle on a specific date rather than providing a window. Guaranteed pickup costs more than standard service because it removes the carrier's scheduling flexibility. Most shippers don't need guaranteed pickup -- a standard 1-5 day window works fine. But for time-critical situations, it's available.

**Hours of Service (HOS)** — Federal regulations that limit how long commercial truck drivers can operate. The key rules: maximum 11 hours of driving after 10 consecutive hours off duty, mandatory 30-minute break after 8 hours of driving, and a 14-hour on-duty window (driving plus non-driving work) after coming on duty. HOS regulations are why cross-country transit takes 7-10 days -- drivers cover roughly 400-500 miles per day within these limits. These rules exist for safety, and ELDs enforce compliance.

**Hot Shot** — A dedicated, single-vehicle transport using a smaller truck (typically a dually pickup with a flatbed trailer) instead of a full-size multi-car carrier. Hot shot transport is faster because the driver is hauling only your vehicle and going directly from pickup to delivery with no multi-stop routing. It's also more expensive -- essentially expedited, dedicated service. Hot shot is common for high-value vehicles, urgent deliveries, and oversized vehicles that don't fit on standard carriers.

**Inoperable Vehicle** — A vehicle that doesn't start, doesn't run, or can't be driven under its own power for loading/unloading. Inoperable vehicles require special equipment -- a winch, dolly, or forklift -- to load onto the carrier. This adds $150-$300 to the shipping cost. Always disclose if your vehicle is inoperable when requesting a quote. Misrepresenting an inoperable vehicle as running causes major problems at pickup.

**Insurance Certificate (COI)** — A document issued by an insurance company confirming that a carrier has active liability and cargo insurance coverage. Before your vehicle ships, you can request the carrier's COI to verify their coverage is current and adequate. Our marketplace verifies insurance for every carrier automatically.

**Intermodal** — Transport that uses more than one mode of transportation (e.g., truck + rail, truck + ship). In auto transport, intermodal isn't common for domestic shipments but is standard for international vehicle shipping where a truck moves the vehicle to a port and a ship carries it overseas.

**Load Board** — A marketplace platform where brokers post available shipments and carriers search for loads that match their routes. Central Dispatch is the largest load board in auto transport. Our AI-powered marketplace functions as an advanced load board with automated carrier matching, binding pricing, and carrier verification.

**Linehaul** — The base transportation charge for moving freight or a vehicle from origin to destination, excluding accessorial charges, fuel surcharges, and other add-ons. In auto transport, the linehaul rate is the core price -- what the carrier charges for the actual transport.

**Lowboy Trailer** — A specialized trailer that sits very low to the ground (18-24 inches deck height) for hauling tall, heavy equipment and oversized vehicles. A Removable Gooseneck (RGN) lowboy detaches at the front to create a ramp for self-loading. Lowboys handle the heaviest loads in the transport industry.

**MC Number (Motor Carrier Number)** — A unique identifier issued by the FMCSA to authorized motor carriers and brokers. This is the most important credential in auto transport. Every legitimate company has one, and you can verify it at FMCSA.gov. The MC number confirms the company is federally authorized to operate. If a company won't provide their MC number, walk away.

**Multi-Car Carrier** — The standard auto transport vehicle: a truck pulling a multi-level trailer designed to carry 7-9 vehicles simultaneously. Open multi-car carriers are the workhorses of the auto transport industry, moving about 90% of all shipped vehicles. The trailer has upper and lower decks, with vehicles secured using ratchet straps and wheel nets.

**Non-Binding Estimate** — A price quote that is not guaranteed and can be changed at any time. In auto transport, non-binding estimates are the tool of bait-and-switch operators -- they quote a low non-binding price to win your booking, then raise it later. Non-binding estimates from low-cost competitors increase by 30-50% before pickup in our experience. Always insist on a binding quote.

**Not-to-Exceed Quote** — A pricing structure where the quoted amount is the maximum you'll pay, but you might pay less if the carrier accepts a lower rate. This is a consumer-friendly pricing model that some brokers use. Our binding quotes function similarly -- the price is fixed and transparent.

**Open Transport** — The standard auto transport method using open (uncovered) multi-car haulers. About 90% of all vehicles ship via open transport. Vehicles are exposed to weather and road dust but are professionally secured with straps and wheel nets. Open transport is the most affordable option and perfectly safe for everyday vehicles.

**Operating Authority** — The legal permission granted by the FMCSA for a company to operate as a motor carrier or broker. Without operating authority, a company cannot legally transport vehicles or arrange transportation for hire. Active operating authority is verified through the FMCSA's SAFER system.

**Oversize Load** — Any vehicle or cargo that exceeds standard legal dimensions: 8.5 feet wide, 13.5 feet tall, or 53 feet long (for a single trailer). Oversize loads require special permits from each state on the route, may require escort (pilot) vehicles, and cost significantly more due to permit fees and reduced carrier speed.

**Pickup Window** — The timeframe during which the carrier will arrive to collect your vehicle, typically 1-5 business days from your first available date. The carrier narrows this to a specific day and calls 12-24 hours ahead. Providing a flexible pickup window results in faster carrier matching and often lower pricing.

**POV (Privately Owned Vehicle)** — Military terminology for a service member's personal vehicle. During PCS (Permanent Change of Station) moves, the military may ship one POV at government expense for OCONUS assignments. The term is used extensively in military relocation logistics.

**RGN (Removable Gooseneck)** — A type of lowboy trailer where the front section detaches to create a ground-level ramp. Equipment can be driven directly onto the trailer under its own power, eliminating the need for a crane. RGN trailers are the standard for heavy equipment transport.

**RORO (Roll-On/Roll-Off)** — An international shipping method where vehicles are driven onto a cargo ship, secured to the deck, and driven off at the destination port. RORO is the most common and affordable method for shipping vehicles overseas. The alternative is container shipping, where the vehicle is loaded into a standard shipping container. RORO is typically 30-40% cheaper than container shipping for standard vehicles.

**Snowbird Season** — The annual migration of residents from northern states to warm-weather destinations (primarily Florida and Arizona) in fall, and back north in spring. Snowbird season creates massive demand spikes on specific auto transport corridors: October-November heading south, March-April heading north. Pricing on these corridors can increase 20-30% during peak snowbird weeks.

**Step-Deck Trailer** — A flatbed trailer with a lowered rear deck that provides extra height clearance for tall cargo. The front section rides at standard flatbed height for the gooseneck connection, then drops down (steps) for the cargo deck. Step-decks are used for vehicles and equipment that exceed the 13.5-foot height limit on a standard flatbed.

**Soft Straps** — Tie-down straps made of nylon webbing with padded or coated contact points, used to secure vehicles without scratching paint, chrome, or bodywork. Reputable auto carriers use soft straps exclusively. Hard metal hooks or chains against your vehicle's finish are a red flag.

**Terminal-to-Terminal** — A transport service where you drop off your vehicle at the carrier's terminal (facility) and pick it up at a terminal near the destination, rather than having the carrier come to your door. Terminal-to-terminal is slightly cheaper than door-to-door because it eliminates the carrier's detour into residential areas. The tradeoff is convenience -- you need to get your vehicle to and from the terminals yourself.

**Tie-Down** — The straps, chains, or webbing used to secure a vehicle to the carrier trailer during transport. In auto transport, tie-downs typically include ratchet straps attached to the vehicle's frame or designated tie-down points, plus wheel nets that cradle each tire. Proper tie-down prevents the vehicle from shifting during braking, acceleration, and cornering.

**Transit Time** — The number of days your vehicle spends on the carrier from pickup to delivery, not including the pickup window. Regional moves: 1-3 days. Mid-range: 3-5 days. Cross-country: 7-10 days.

**Wheel Chock** — A wedge or cradle placed against the vehicle's tires to prevent rolling during transport. On motorcycle carriers, wheel chocks are metal or rubber cradles that lock the front wheel in an upright position. On auto carriers, chocks work in conjunction with tie-down straps to fully immobilize the vehicle.

**Wheel Net** — A heavy-duty strap system that wraps over and around the vehicle's tire and wheel, securing it to the trailer deck. Wheel nets are a primary securing method on multi-car carriers because they don't contact the vehicle's body or frame -- only the tire and wheel.

**Winch** — A mechanical device used to pull inoperable vehicles onto a carrier trailer. Carriers equipped with winches can handle non-running vehicles that can't be driven onto the trailer under their own power. Winch loading adds $150-$300 to the transport cost and must be arranged in advance.
