Final answer:
Freight class for LTL shipment is chosen based on both weight and dimensions ( option c) , along with other factors like density and handling requirements. Freight classes designated by NMFTA range from 50 to 500, with lower classes being heavier and less costly to transport.
Step-by-step explanation:
To choose a freight class for a less-than-truckload (LTL) shipment, the proper option is c) Based on both weight and dimensions. Freight class is determined by a number of factors including not only the weight and dimensions of the shipment but also the density, storage capability, handling requirements, and the product's value.
The National Motor Freight Traffic Association (NMFTA) categorizes freight into 18 different classes ranging from 50 to 500. The lower the freight class, such as 50, typically indicates a heavier, denser shipment that is easier and less expensive to transport. In contrast, higher classes typically represent lighter, less dense shipments that take up more space and are generally more expensive to transport.
