Trucking Glossary

Whether you are new to the trucking industry or have been working as a commercial truck driver for ages, you know the trucking industry has invented a vocabulary of its own. This can get confusing if you are unfamiliar with some of the key terms, which is why we put together this glossary of terms that are commonly used among commercial drivers in the trucking industry.  


After-Market Parts

Parts that are produced by other vendors rather than being produced by the Original Equipment Manufacturer (OEM)

Bill of Lading

A tractor without a trailer attached


CDL (Commercial Driver’s License)

Required to drive any commercial vehicle over 26,000 lbs Gross Vehicle Weight


Day Cab

Heavy-duty truck with no sleeper



Driving to a destination without any cargo on the truck. Since most trucks are paid by the mile when loaded, this would be moving the truck for free.


ELD (Electronic Logging Device)

This is required on all trucks and records speed, time in service, driver’s duty status, and hours of service for the driver


Elite Support

Daimler Truck North America’s format to measure minimum dealership standards to qualify as a certified location

LTL (Less-Than-Truckload)

The amount of freight is less than the amount needed to be charged at the regular truckload rate (i.e. the freight is less than 10,000 lbs). Since it is less freight than usual, it may be consolidated with something else or it will be shipped as is for a less-than-truckload rate.


OEM (Original Equipment Manufacturer)

This is who builds the truck; they are the original producer of the vehicle’s components, so any parts they put out are identical to the parts the truck was originally made with


Peddle Run

Reefer (Truck)
