QuestionPrior tothe 20th century, freight was generally transported overland via trains and railroads.During this time, trains were essential, and they werehighlyefficient at moving large amounts of freight.But, they could only deliver that freight to urban centers for distribution by horse-drawn transport.Though there were several trucks throughout this time, theywere usedmore as space for advertising that for actual utility.At this time, the use of range for trucks was quite challenging.The use of electric engines, lack of paved rural roads, and small load capacities limited trucks to most short-haul urban routes.

QuestionIn 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.

QuestionTrucks of the era mostly used two-cylinder engines and had a carrying capacity of 1,500 to 2,000 kilograms (3,300 to 4,400 lb). In 1904, 700 heavy trucks were built in the United States, 1000 in 1907, 6000 in 1910, and 25000 in 1914. A Benz truck modified by Netphener company (1895)

QuestionTrailer 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.

QuestionA business route (occasionally city route) in the United States and Canada is a short special route connected to a parent numbered highway at its beginning, then routed through the central business district of a nearby city or town, and finally reconnecting with the same parent numbered highway again at its end.


Compliance, Safety, and Accountability (CSA) are fundamental to the FMCSA's compliance program. The purpose of the CSA program is to oversee and focus on motor carriers' safety performance. To enforce such safety regulations, the CSA conducts roadside inspections and crash investigations.The program issues violations when instances of noncompliance with CSA safety regulationsare exposed.
Unfortunately, the CSA's number of safety investigation teams and state law enforcement partners are rather small in comparison to the millions of CMV companies and commercial driver license (CDL) holders. A key factor in the CSA programis knownas the Safety Measurement System (SMS).This system relies on data analysis to identify unsafe companies to arrange them for safety interventions. SMS is incredibly helpful to CSA in finding and holding companies accountable for safety performance.
