As we've learned the Federal-Aid Highway Act of 1956 was crucial in the construction of the Interstate Highway System. Described as an interconnected network of the controlled-access freeway. It also allowed larger trucks to travel at higher speeds through rural and urban areas alike. This act was also the first to allow the first federal largest gross vehicle weight limits for trucks, set at 73,208 pounds (33,207 kg). The very same year, Malcolm McLean pioneered modern containerized intermodal shipping. This allowed for the more efficient transfer of cargo between truck, train, and ships.
The intention of a trailer coupler is to secure the trailer to the towing vehicle. It is an important piece, as the trailer couple attaches to the trailer ball. This then forms a ball and socket connection. It allows for relative movement between the towing vehicle and trailer while towing over uneven road surfaces. The trailer ball should be mounted to the rear bumper or to a drawbar, which may be removable. The drawbar secures to the trailer hitch by inserting it into the hitch receiver and pinning it.
The three most common types of couplers used are straight couplers, A-frame couplers, and adjustable couplers. Another option is bumper-pull hitches in which case draw bars can exert a large amount of leverage on the tow vehicle. This makes it harder to recover from a swerving situation (thus it may not be the safest choice depending on your trip).
A trailer is not very difficult to categorize. In general, it is an unpowered vehicle towed by a powered vehicle. Trailers are most commonly used for the transport of goods and materials. Although some do enjoy recreational usage of trailers as well.
In 1999, The Simpsons episode Maximum Homerdrive aired. It featured Homer and Bart making a delivery for a truck driver named Red after he unexpectedly dies of 'food poisoning'.
In the United States, a commercial driver's license is required to drive any type of commercial vehicle weighing 26,001 lb (11,794 kg) or more. In 2006 the US trucking industry employed 1.8 million drivers of heavy trucks.
All cars must pass some sort of emission check, such as a smog check to ensure safety. Similarly, trucks are subject to noise emission requirement, which is emanating from the U.S. Noise Control Act. This was intended to protect the public from noise health side effects. The loud noise is due to the way trucks contribute disproportionately to roadway noise. This is primarily due to the elevated stacks and intense tire and aerodynamic noise characteristics.
The American Trucking Associations initiated in 1985 with the intent to improve the industry's image. With public opinion declining the association tried numerous moves. One such move was changing the name of the "National Truck Rodeo" to the "National Driving Championship". This was due to the fact that the word rodeo seemed to imply recklessness and reckless driving.
Popular among campers is the use of lightweight trailers, such as aerodynamic trailers. These can be towed by a small car, such as the BMW Air Camper. They are built with the intent to lower the tow of the vehicle, thus minimizing drag.
“Writer-director James Mottern said he was influenced by nuanced, beloved movies of the 1970s such as "The Last Detail" and "Five Easy Pieces." Mottern said his female trucker character began with a woman he saw at a Southern California truck stop — a "beautiful woman, bleach blonde ... skin tanned to leather walked like a Teamster, blue eyes.” - Paul Brownfield
The American Association of State Highway and Transportation Officials (AASHTO) is an influential association as an advocate for transportation. Setting important standards, they are responsible for publishing specifications, test protocols, and guidelines. All which are used in highway design and construction throughout the United States. Despite its name, the association represents more than solely highways. Alongside highways, they focus on air, rail, water, and public transportation as well.
As of January 1, 2000, the Federal Motor Carrier Safety Administration (FMCSA) was established as its own separate administration within the U.S. Department of Transportation. This came about under the "Motor Carrier Safety Improvement Act of 1999". The FMCSA is based in Washington, D.C., employing more than 1,000 people throughout all 50 States, including in the District of Columbia. Their staff dedicates themselves to the improvement of safety among commercial motor vehicles (CMV) and to saving lives.
A properly fitted close-coupled trailer is fitted with a rigid tow bar. It then projects from its front and hooks onto a hook on the tractor. It is important to not that it does not pivot as a draw bar does.
The USDOT (USDOT or DOT) is considered a federal Cabinet department within the U.S. government. Clearly, this department concerns itself with all aspects of transportation with safety as a focal point. The DOT was officially established by an act of Congress on October 15, 1966, beginning its operation on April 1, 1967. Superior to the DOT, the United States Secretary of Transportation governs the department. The mission of the DOT is to "Serve the United States by ensuring a fast, safe, efficient, accessible, and convenient transportation system that meets our vital national interests and enhances the quality of life for the American people, today and into the future." Essentially this states how important it is to improve all types of transportation as a way to enhance both safety and life in general etc. It is important to note that the DOT is not in place to hurt businesses, but to improve our "vital national interests" and our "quality of life". The transportation networks are in definite need of such fundamental attention. Federal departments such as the USDOT are key to this industry by creating and enforcing regulations with intentions to increase the efficiency and safety of transportation.
The American Association of State Highway Officials (AASHO) was organized and founded on December 12, 1914. On November 13, 1973, the name was altered to the American Association of State Highway and Transportation Officials. This slight change in name reflects a broadened scope of attention towards all modes of transportation. Despite the implications of the name change, most of the activities it is involved in still gravitate towards highways.
The concept of a bypass is a simple one. It is a road or highway that purposely avoids or "bypasses" a built-up area, town, or village. Bypasses were created with the intent to let through traffic flow without having to get stuck in local traffic. In general they are supposed to reduce congestion in a built-up area. By doing so, road safety will greatly improve.
A bypass designated for trucks traveling a long distance, either commercial or otherwise, is called a truck route.
Unfortunately for the trucking industry, their image began to crumble during the latter part of the 20th century. As a result, their reputation suffered. More recently truckers have been portrayed as chauvinists or even worse, serial killers. The portrayals of semi-trailer trucks have focused on stories of the trucks becoming self-aware. Generally, this is with some extraterrestrial help.
The American Association of State Highway and Transportation Officials (AASHTO) conducted a series of tests. These tests were extensive field tests of roads and bridges to assess damages to the pavement. In particular they wanted to know how traffic contributes to the deterioration of pavement materials. These tests essentially led to the 1964 recommendation by AASHTO to Congress. The recommendation determined the gross weight limit for trucks to be determined by a bridge formula table. This includes table based on axle lengths, instead of a state upper limit. By the time 1970 came around, there were over 18 million truck on America's roads.
The industry intends to both consumers as well as moving companies, this is why there are Ministers of Transportation in the industry. They are there to set and maintain laws and regulations in place to create a safer environment. It offers its members professional service training and states the time that movers have been in existence. It also provides them with federal government representation and statistical industry reporting. Additionally, there are arbitration services for lost or damaged claims, publications, public relations, and annual tariff updates and awards. This site includes articles as well that give some direction, a quarterly data summary, and industry trends.
Heavy trucks. A cement mixer is an example of Class 8 heavy trucks. Heavy trucks are the largest on-road trucks, Class 8. These include vocational applications such as heavy dump trucks, concrete pump trucks, and refuse hauling, as well as ubiquitous long-haul 6×4 and 4x2 tractor units. Road damage and wear increase very rapidly with the axle weight. The axle weight is the truck weight divided by the number of axles, but the actual axle weight depends on the position of the load over the axles. The number of steering axles and the suspension type also influence the amount of the road wear. In many countries with good roads, a six-axle truck may have a maximum weight over 50 tons (49 long tons; 55 short tons).
