The trucking industry has made a large historical impact since the early 20th century. It has affected the U.S. both politically as well as economically since the notion has begun. Previous to the invention of automobiles, most freight was moved by train or horse-drawn carriage. Trucks were first exclusively used by the military during World War I.
After the war, construction of paved roads increased. As a result, trucking began to achieve significant popularity by the 1930's. Soon after trucking became subject to various government regulation, such as the hours of service. During the later 1950's and 1960's, trucking accelerated due to the construction of the Interstate Highway System. The Interstate Highway System is an extensive network of freeways linking major cities cross country.
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 the United States, shipments larger than about 7,000 kg (15,432 lb) are classified as truckload freight (TL). It is more efficient and affordable for a large shipment to have exclusive use of one larger trailer. This is opposed to having to share space on a smaller Less than Truckload freight carrier.
Invented in 1890, the diesel engine was not an invention that became well known in popular culture. It was not until the 1930's for the United States to express further interest for diesel engines to be accepted. Gasoline engines were still in use on heavy trucks in the 1970's, while in Europe they had been entirely replaced two decades earlier.
A semi-trailer is almost exactly what it sounds like, it is a trailer without a front axle. Proportionally, its weight is supported by two factors. The weight falls upon a road tractor or by a detachable front axle assembly, known as a dolly. Generally, a semi-trailer is equipped with legs, known in the industry as "landing gear". This means it can be lowered to support it when it is uncoupled. In the United States, a trailer may not exceed a length of 57 ft (17.37 m) on interstate highways. However, it is possible to link two smaller trailers together to reach a length of 63 ft (19.20 m).
A 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.
The United States' Interstate Highway System is full of bypasses and loops with the designation of a three-digit number. Usually beginning with an even digit, it is important to note that this pattern is highly inconsistent. For example, in Des Moines, Iowa the genuine bypass is the main route. More specifically, it is Interstate 35 and Interstate 80, with the loop into downtown Des Moines being Interstate 235. As it is illustrated in this example, they do not always consistently begin with an even number. However, the 'correct' designation is exemplified in Omaha, Nebraska. In Omaha, Interstate 480 traverses the downtown area, which is bypassed by Interstate 80, Interstate 680, and Interstate 95. Interstate 95 then in turn goes through Philadelphia, Pennsylvania. Furthermore, Interstate 295 is the bypass around Philadelphia, which leads into New Jersey. Although this can all be rather confusing, it is most important to understand the Interstate Highway System and the role bypasses play.
In the United States, the Commercial Motor Vehicle Safety Act of 1986 established minimum requirements that must be met when a state issues a commercial driver's license CDL. It specifies the following types of license:
- Class A CDL drivers. Drive vehicles weighing 26,001 pounds or greater, or any combination of vehicles weighing 26,001 pounds or greater when towing a trailer weighing more than 10,000 pounds. Transports quantities of hazardous materials that require warning placards under Department of Public Safety regulations.
- Class A Driver License permits. Is a step in preparation for Class A drivers to become a Commercial Driver.
- Class B CDL driver. Class B is designed to transport 16 or more passengers (including driver) or more than 8 passengers (including the driver) for compensation.
This includes, but is not limited to, tow trucks, tractor trailers, and buses.
The Federal Bridge Gross Weight Formula is a mathematical formula used in the United States to determine the appropriate gross weight for a long distance moving vehicle, based on the axle number and spacing. Enforced by the Department of Transportation upon long-haul truck drivers, it is used as a means of preventing heavy vehicles from damaging roads and bridges. This is especially in particular to the total weight of a loaded truck, whether being used for commercial moving services or for long distance moving services in general.
According to the Federal Bridge Gross Weight Formula, the total weight of a loaded truck (tractor and trailer, 5-axle rig) cannot exceed 80,000 lbs in the United States. Under ordinary circumstances, long-haul equipment trucks will weight about 15,000 kg (33,069 lbs). This leaves about 20,000 kg (44,092 lbs) of freight capacity. Likewise, a load is limited to the space available in the trailer, normally with dimensions of 48 ft (14.63 m) or 53 ft (16.15 m) long, 2.6 m (102.4 in) wide, 2.7 m (8 ft 10.3 in) high and 13 ft 6 in or 4.11 m high.
Full truckload carriers normally deliver a semi-trailer to a shipper who will fill the trailer with freight for one destination. Once the trailer is filled, the driver returns to the shipper to collect the required paperwork. Upon receiving the paperwork the driver will then leave with the trailer containing freight. Next, the driver will proceed to the consignee and deliver the freight him or herself. At times, a driver will transfer the trailer to another driver who will drive the freight the rest of the way. Full Truckload service (FTL) transit times are generally restricted by the driver's availability. This is according to Hours of Service regulations and distance. It is typically accepted that Full Truckload carriers will transport freight at an average rate of 47 miles per hour. This includes traffic jams, queues at intersections, other factors that influence transit time.
The definition of business logistics can be difficult to understand. Logistics can be simply put as a means of management that plans, implements, and controls the efficiency of the business. The notion of business logistics incorporates all sectors of the industry. It is used as a means to manage the fruition of project life cycles, supply chains, and resultant efficiency.
Implemented in 2014, the National Registry, requires all Medical Examiners (ME) who conduct physical examinations and issue medical certifications for interstate CMV drivers to complete training on FMCSA’s physical qualification standards, must pass a certification test. This is to demonstrate competence through periodic training and testing. CMV drivers whose medical certifications expire must use MEs on the National Registry for their examinations.
FMCSA has reached its goal of at least 40,000 certified MEs signing onto the registry. All this means is that drivers or movers can now find certified medical examiners throughout the country who can perform their medical exam. FMCSA is preparing to issue a follow-on “National Registry 2” rule stating new requirements. In this case, MEs are to submit medical certificate information on a daily basis. These daily updates are sent to the FMCSA, which will then be sent to the states electronically. This process will dramatically decrease the chance of drivers falsifying medical cards.
Logistics is generally the ability to organize and put in place many complex operations at a single time. It is the management of the flow of things to meet the needs of customers or corporations. Resources managed in logistics includes tangible items such as food, materials, animals, equipment, etc. Not to mention the items that are not tangible such as time and information. This means that the movement of physical items, such as in the moving industry, involves a clear understanding of solid workflow. Such logistics can involve the handling of necessary materials, producing, packaging, inventory, transportation, warehousing, and often security.
Throughout the United States, bypass routes are a special type of route most commonly used on an alternative routing of a highway around a town. Specifically when the main route of the highway goes through the town. Originally, these routes were designated as "truck routes" as a means to divert trucking traffic away from towns. However, this name was later changed by AASHTO in 1959 to what we now call a "bypass". Many "truck routes" continue to remain regardless that the mainline of the highway prohibits trucks.
The 1950's were quite different than the years to come. They were more likely to be considered "Knights of the Road", if you will, for helping stranded travelers. In these times truck drivers were envied and were viewed as an opposition to the book "The Organization Man". Bestseller in 1956, author William H. Whyte's novel describes "the man in the gray flannel suit", who sat in an office every day. He's describing a typical office style job that is very structured with managers watching over everyone. Truck drivers represented the opposite of all these concepts. Popular trucking songs glorified the life of drivers as independent "wanderers". Yet, there were attempts to bring back the factory style efficiency, such as using tachnographs. Although most attempts resulted in little success. Drivers routinely sabotaged and discovered new ways to falsify the machine's records.
In 1984 the animated TV series The Transformers told the story of a group of extraterrestrial humanoid robots. However, it just so happens that they disguise themselves as automobiles. Their leader of the Autobots clan, Optimus Prime, is depicted as an awesome semi-truck.
The Federal-Aid Highway Amendments of 1974 established a federal maximum gross vehicle weight of 80,000 pounds (36,000 kg). It also introduced a sliding scale of truck weight-to-length ratios based on the bridge formula. Although, they did not establish a federal minimum weight limit. By failing to establish a federal regulation, six contiguous in the Mississippi Valley rebelled. Becoming known as the "barrier state", they refused to increase their Interstate weight limits to 80,000 pounds. Due to this, the trucking industry faced a barrier to efficient cross-country interstate commerce.
With the ending of World War I, several developments were made to enhance trucks. Such an example would be by putting pneumatic tires replaced the previously common full rubber versions. These advancements continued, including electric starters, power brakes, 4, 6, and 8 cylinder engines. Closed cabs and electric lighting followed. The modern semi-trailer truck also debuted. Additionally, touring car builders such as Ford and Renault entered the heavy truck market.
