Beginning the the early 20th century, the 1920's saw several major advancements. There was improvement in rural roads which was significant for the time.The diesel engine, which are 25-40% more efficient than gas engines were also a major breakthrough.We also saw the standardization of truck and trailer sizes along with fifth wheel coupling systems. Additionally power assisted brakes and steering developed. By 1933, all states had some form of varying truck weight regulation.
The Federal Motor Carrier Safety Administration (FMCSA) is an agency within the United States Department of Transportation.The purpose of the FMCSA is to regulate safety within the trucking and moving industry in the United States.The FMCSA enforces safety precautions that reduce crashes, injuries, and fatalities involving large trucks and buses.
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 rise of technological development gave rise to the modern trucking industry.There a few factors supporting this spike in the industry such as the advent of the gas-powered internal combustion engine.Improvement in transmissions is yet another source,justlike the move away from chain drives to gear drives. And of course the development of the tractor/semi-trailer combination.
The first state weight limits for truckswere determinedand put in place in 1913.Only four states limited truck weights, from a low of 18,000 pounds (8,200 kg) in Maine to a high of 28,000 pounds (13,000 kg) in Massachusetts. The intention of these laws was to protect the earth and gravel-surfaced roads. In this case, particular damages due to the iron and solid rubber wheels of early trucks. By 1914 there were almost 100,000 trucks on America's roads.As a result of solid tires, poor rural roads, and amaximumspeed of 15 miles per hour (24km/h) continued to limit the use of these trucks tomostlyurban areas.
