Common trucking industry terms


A returning load that brings the driver near their company’s terminal or home area. Backhauling requires planning for roundtrip hauls and mapping out routes to ensure goods are transported on every leg of a truck’s journey.


A truck without an attached trailer at a given time is said to be “bobtailing.” Because a bobtail truck does not contain any freight, it doesn’t generate revenue for its owner.

Also called freight receiver, a carrier is a company or a person who transports goods by land, water, or air. Carriers work with shippers to move goods from one place to the other.


The practice of driving a semi-truck with an empty trailer (also known as deadheading). A deadhaul happens when a trucker returns the empty container to the point of origin. Deadhauling is not the same as bobtailing, which happens when driving a truck is driving without a trailer attached.


Most shippers and receivers have a 2-hour window to load or unload a truck. Any time after that window is considered detention time. During detention, a driver must wait over the allotted time to be loaded or unloaded, which can cause them to miss other pick-ups and cut into profits.


A dispatcher directs the movement of trucks and freight. Usually, dispatchers communicate with truckers throughout their trips to monitor progress and address any issues or problems that may come up on the road.
