More products are shipped by truck than by another means. Trucks can go anywhere there are roads, including straight to customer’s homes. By contrast, planes, trains, and ships are limited as to where they can go. Shipping by truck is also fast relative to other modes (except for air transportation). However, it’s also fairly expensive. Some goods—especially those that are heavy or bulky—would require so many trucks and drivers it would be economically unfeasible to use them over long distances. Coal is a good example of such a product. It would take four to five hundred trucks and drivers to haul the amount of freight that one coal train can. The amount of CO2 emitted by trucks is also high relative to some of the other transportation modes, so it’s not the greenest solution.
