A commercial driver's license (CDL) is a driver's license required to operate large or heavy vehicles.
The public idea of the trucking industry in the United States popular culture has gone through many transformations. However, images of the masculine side of trucking are a common theme throughout time. The 1940's first made truckers popular, with their songs and movies about truck drivers. Then in the 1950's they were depicted as heroes of the road, living a life of freedom on the open road. Trucking culture peaked in the 1970's as they were glorified as modern days cowboys, outlaws, and rebels. Since then the portrayal has come with a more negative connotation as we see in the 1990's. Unfortunately, the depiction of truck drivers went from such a positive depiction to that of troubled serial killers.
During the latter part of the 20th century, we saw a decline of the trucking culture. Coinciding with this decline was a decline of the image of truck drivers, as they became negatively stigmatized. As a result of such negativity, it makes sense that truck drivers were frequently portrayed as the "bad guy(s)" in movies.
The Federal Bridge Law handles relations between the gross weight of the truck, the number of axles, and the spacing between them. This is how they determine is the truck can be on the Interstate Highway system. Each state gets to decide the maximum, under the Federal Bridge Law. They determine by vehicle in combination with axle weight on state and local roads
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.
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.
Without strong land use controls, buildings are too often built in town right along a bypass. This results with the conversion of it into an ordinary town road, resulting in the bypass becoming as congested as the local streets. On the contrary, a bypass is intended to avoid such local street congestion. Gas stations, shopping centers, along with various other businesses are often built alongside them. They are built in hopes of easing accessibility, while home are ideally avoided for noise reasons.
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.
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.
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 Federal Motor Carrier Safety Administration (FMCSA) issues Hours of Service regulations. At the same time, they govern the working hours of anyone operating a commercial motor vehicle (CMV) in the United States. Such regulations apply to truck drivers, commercial and city bus drivers, and school bus drivers who operate CMVs. With these rules in place, the number of daily and weekly hours spent driving and working is limited. The FMCSA regulates the minimum amount of time drivers must spend resting between driving shifts. In regards to intrastate commerce, the respective state's regulations apply.
A circumferential route refers to a public transportation system that follows the route in the shape of a circle. Over time a nickname developed in the European Union, calling transportation networks such as these a "ring road". This is no surprise as Europe has several famous "ring roads" such as the Berliner Ring, the Brussels Ring, the Amsterdam Ring, the Boulevard Périphérique around Paris and the Leeds Inner and Outer ring roads. Other countries adopted the term as well which in turn made the name go international. Australia's Melbourne's Western Ring Road and India's Hyderabad's Outer Ring Road both adopted the name. However in Canada, the term is most commonly used, with "orbital" used to a much lesser extent.
On the contrary, the United States calls many "ring roads" as belt-lines, beltways, or loops instead. For example, the Capital Beltway around Washington, D.C. Some ring roads use terminology such as "Inner Loop" and "Outer Loop". This is, of course, for the sake of directional sense, since compass directions cannot be determined around the entire loop.
Released in 1998, the film Black Dog featured Patrick Swayze as a truck driver who made it out of prison. However, his life of crime continued, as he was manipulated into the transportation of illegal guns. Writer Scott Doviak has described the movie as a "high-octane riff on White Line Fever" as well as "a throwback to the trucker movies of the 70s".
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.
The term 'trailer' is commonly used interchangeably with that of a travel trailer or mobile home. There are varieties of trailers and manufactures housing designed for human habitation. Such origins can be found historically with utility trailers built in a similar fashion to horse-drawn wagons. A trailer park is an area where mobile homes are designated for people to live in.
In the United States, trailers ranging in size from single-axle dollies to 6-axle, 13 ft 6 in (4,115 mm) high, 53 ft (16,154 mm) in long semi-trailers is common. Although, when towed as part of a tractor-trailer or "18-wheeler", carries a large percentage of the freight. Specifically, the freight that travels over land in North America.
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.
Known as a truck in the U.S., Canada, Australia, New Zealand, Puerto Rico, it is essentially a 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 being mechanically like 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.
