In 2009, the book 'Trucking Country: The Road to America's Walmart Economy' debuted, written by author Shane Hamilton. This novel explores the interesting history of trucking and connects certain developments.Particularly how such development in the trucking industry have helped the so-called big-box stored. Examples of these would include Walmart or Target, they dominate the retail sector of the U.S. economy. Yet, Hamilton connects historical and present-day evidence that connects such correlations.

The year 1611 marked an important time for trucks, as that is when the word originated. The usage of "truck" referred to the small strong wheels on ships' cannon carriages. Further extending its usage in 1771, it came to refer to carts for carrying heavy loads. In 1916 it became shortened, calling it a "motor truck".While since the 1930's its expanded application goes as faras tosay "motor-powered load carrier".

Trailer stability can be defined as the tendency of a trailer to dissipate side-to-side motion. The initial motion may be caused by aerodynamic forces, such as from a cross wind or a passing vehicle. One common criterion for stability is the center of mass location with respect to the wheels, which can usually be detected by tongue weight. If the center of mass of the trailer is behind its wheels, therefore having a negative tongue weight, the trailer will likely be unstable. Another parameter which is less commonly a factor is the trailer moment of inertia. Even if the center of mass is forward of the wheels, a trailer with a long load, and thus large moment of inertia, may be unstable.

As we know in the trucking industry, some trailers are part of large trucks, which we call semi-trailer trucks for transportation of cargo.Trailers may alsobe usedin a personal manner as well, whether for personal or small business purposes.

Advocation for better transportation beganhistoricallyin the late 1870s of the United States. This is when the Good Roads Movement first occurred, lasting all the way throughout the 1920s. Bicyclist leaders advocated for improved roads.Their acts led to the turning of local agitation into the national political movement it became.
