Freight has its own vocabulary. These are the terms shippers hear most often when booking truckload shipments, defined in plain English.

Accessorial charge
A charge for a service beyond standard pickup and delivery, such as detention, a liftgate, tarping or a layover.
Bill of lading (BOL)
The document that serves as the receipt for freight, describes the shipment and acts as a contract of carriage between shipper and carrier.
Broker
A company licensed by FMCSA to arrange the transportation of freight by an authorized motor carrier. Brokers do not haul freight themselves.
Consignee
The party receiving the freight at the delivery location.
Detention
Time a truck is held at pickup or delivery beyond the agreed free time, which may result in a charge.
Drop deck
Another name for a step deck trailer.
Dry van
An enclosed, non-temperature-controlled trailer, most commonly 53 feet long.
Flatbed
An open-deck trailer without sides or a roof, loaded from the side or top.
FTL / truckload
A shipment that uses an entire trailer, as opposed to less-than-truckload (LTL) freight that shares a trailer.
Lane
The route between a pickup location and a delivery location, such as Chicago, IL to Dallas, TX.
Layover
When a driver must wait overnight or longer to load or unload, often resulting in a charge.
Lumper
A third-party worker who unloads freight at some receiving facilities, usually for a fee.
MC number
The operating-authority docket number FMCSA assigns to brokers and for-hire carriers.
Motor carrier
A trucking company authorized to transport freight for hire.
Oversize load
A load that exceeds legal width, height or length limits and requires permits.
Overweight load
A load that exceeds legal gross or axle weight limits and requires permits.
Proof of delivery (POD)
The signed document confirming freight was delivered, usually the bill of lading signed by the consignee.
Rate confirmation
The agreement between a broker and a carrier that confirms the rate and the terms for a specific load.
Reefer
A refrigerated trailer for temperature-controlled freight.
RGN
Removable gooseneck trailer — a low-deck trailer whose front detaches so equipment can be driven on.
Shipper
The party sending the freight.
Step deck
An open-deck trailer with a lower main deck that allows taller freight.
Superload
A load so large or heavy that a state classifies it separately from routine oversize permits.
Tarping
Covering open-deck freight with tarps to protect it from weather or road debris.
TONU
Truck ordered, not used — a charge that may apply when a truck is dispatched but the load is canceled or not ready.
USDOT number
The identifier FMCSA assigns to companies subject to its regulations, used to look up a company's registration and status.
