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.
In 1938, the now-eliminated Interstate Commerce Commission (ICC) enforced the first Hours of Service (HOS) rules. Drivers became limited to 12 hours of work within a 15-hour period.At this time, work included loading, unloading, driving, handling freight, preparing reports, preparing vehicles for service, or performing any other duty in relation to the transportation of passengers or property.
The ICC intended for the 3-hour difference between 12 hours of work and 15 hours on-duty tobe usedfor meals and rest breaks.This meant that the weekly maxwas limitedto 60 hours over 7 days (non-dailydrivers), or 70 hours over 8 days (daily drivers). With these rules in place, it allowed 12 hours of work within a 15-hour period, 9 hours of rest, with 3 hours for breaks within a 24-hour day.
As the American Interstate Highway System began to expand in the 1950's, the trucking industry began to take over a large market share. That is, a large share of the transportation of goods throughout the country. Before this era, trains hadbeen reliedon to transport the bulk of the goods cross country or state to state.The Interstate Highway System was influential as it allows for merchandise to travel door to door with ease.Since then, truckload carriers have taken advantage of the interstate system, especially when performing a long distance move.Typically, they bring the merchandise from one distribution center of the country to another part of the country.The increase in truckload freight transportation has reduced the time it takes to transport the goods.Whether the freightwas manufacturedor produced for the different areasinternationally, the time it takes to transport goods has decreased dramatically.
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.
Known as a truck in the U.S., Canada, Australia, New Zealand, Puerto Rico, it isessentiallya motor vehicle designed to transport cargo.Otherwise known as a lorry in the United Kingdom, Ireland, South Africa, and Indian Subcontinent.Trucks vary not only in their types, but also in size, power, and configuration, the smallest beingmechanicallylike an automobile. Commercial trucks may be very large and powerful, configured to mount specialized equipment.These are necessary in the case of fire trucks, concrete mixers, and suction excavators etc.
