Receiving nation attention during the 1960's and 70's, songs and movies about truck driving were major hits. Finding solidarity, truck drivers participated in widespread strikes. Truck drivers from all over opposed the rising cost of fuel. Not to mention this is during the energy crises of 1873 and 1979. In 1980 the Motor Carrier Act drastically deregulated the trucking industry. Since then trucking has come to dominate the freight industry in the latter part of the 20th century. This coincided with what are now known as 'big-box' stores such as Target or Wal-Mart.
In the United States, the term 'full trailer' is used for a freight trailer supported by front and rear axles and pulled by a drawbar. This term is slightly different in Europe, where a full trailer is known as an A-frame drawbar trail. A full trailer is 96 or 102 in (2.4 or 2.6 m) wide and 35 or 40 ft (11 or 12 m) long.
The decade of the 70s saw the heyday of truck driving, and the dramatic rise in the popularity of "trucker culture". Truck drivers were romanticized as modern-day cowboys and outlaws (and this stereotype persists even today). This was due in part to their use of citizens' band (CB) radio to relay information to each other regarding the locations of police officers and transportation authorities. Plaid shirts, trucker hats, CB radios, and using CB slang were popular not just with drivers but among the general public.
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.
“The association of truckers with cowboys and related myths was perhaps most obvious during the urban-cowboy craze of the late 1970s, a period that saw middle-class urbanites wearing cowboy clothing and patronizing simulated cowboy nightclubs. During this time, at least four truck driver movies appeared, CB radio became popular, and truck drivers were prominently featured in all forms of popular media.” — Lawrence J. Ouellet
Another film released in 1975, White Line Fever, also involved truck drivers. It tells the story of a Vietnam War veteran who returns home to take over his father's trucking business. But, he soon finds that corrupt shippers are trying to force him to carry illegal contraband. While endorsing another negative connotation towards the trucking industry, it does portray truck drivers with a certain wanderlust.
There are certain characteristics of a truck that makes it an "off-road truck". They generally standard, extra heavy-duty highway-legal trucks. Although legal, they have off-road features like front driving axle and special tires for applying it to tasks such as logging and construction. The purpose-built off-road vehicles are unconstrained by weighing limits, such as the Libherr T 282B mining truck.
Medium trucks are larger than light but smaller than heavy trucks. In the US, they are defined as weighing between 13,000 and 33,000 pounds (6,000 and 15,000 kg). For the UK and the EU, the weight is between 3.5 and 7.5 tons (3.9 and 8.3 tons). Local delivery and public service (dump trucks, garbage trucks, and fire-fighting trucks) are around this size.
Trailer 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.
AMSA wanted to help consumers avoid untrustworthy or illegitimate movers. In January 2008, AMSA created the ProMover certification program for its members. As a member, you must have federal interstate operating authority. Members are also required to pass an annual criminal back check, be licensed by the FMCSA, and agree to abide by ethical standards. This would include honesty in advertising and in business transaction with customers. Each must also sign a contract committing to adhere to applicable Surface Transportation Board and FMCSA regulations. AMSA also takes into consideration and examines ownership. They are very strict, registration with state corporation commissions. This means that the mover must maintain at least a satisfactory rating with the Better Business Bureau (BBB). As one can imagine, those that pass are authorized to display the ProMove logo on the websites and in marketing materials. However, those that fail will be expelled from the program (and AMSA) if they cannot correct discrepancies during probation.
“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
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 to be used for meals and rest breaks. This meant that the weekly max was limited to 60 hours over 7 days (non-daily drivers), 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.
The FMCSA is a well-known division of the United States Department of Transportation (USDOT). It is generally responsible for the enforcement of FMCSA regulations. The driver of a CMV must keep a record of working hours via a log book. This record must reflect the total number of hours spent driving and resting, as well as the time at which the change of duty status occurred. In place of a log book, a motor carrier may choose to keep track of their hours using an electronic on-board recorder (EOBR). This automatically records the amount of time spent driving the vehicle.
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.
In today's popular culture, recreational vehicles struggle to find their own niche. Travel trailers or mobile home with limited living facilities, or where people can camp or stay have been referred to as trailers. Previously, many would refer to such vehicles as towable trailers.
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).
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.
