In the United States, commercial truck classificationis fixed byeach vehicle's gross vehicle weight rating (GVWR). There are 8 commercial truck classes, ranging between 1 and 8.Trucks are also classified in a more broad way by the DOT's Federal Highway Administration (FHWA). The FHWA groups them together, determining classes 1-3 as light duty, 4-6 as medium duty, and 7-8 as heavy duty.The United States Environmental Protection Agency has its own separate system of emission classifications for commercial trucks.Similarly, the United States Census Bureau had assigned classifications of its own in its now-discontinued Vehicle Inventory and Use Survey (TIUS,formerlyknown as the Truck Inventory and Use Survey).
Truckload shipping is the movement of large amounts of cargo.In general, they move amounts necessary to fill an entire semi-trailer or inter-modal container.A truckload carrier is a trucking company that generally contracts an entire trailer-load to a single customer. This is quite the opposite of a Less than Truckload (LTL) freight services.Less than Truckload shipping services generally mix freight from several customers in each trailer.An advantage Full Truckload shipping carriers have over Less than Truckload carrier services is that the freight isn't handled during the trip.Yet, in an LTL shipment, goods will generallybe transportedon several different trailers.
The basics of all trucks are not difficult, as they share common construction.They are generally made of chassis, a cab, an area for placing cargo or equipment, axles, suspension, road wheels, and engine and a drive train. Pneumatic, hydraulic, water, and electrical systems may also be present. Many also tow one or more trailers or semi-trailers, which also vary inmultipleways but are similar as well.
