“Country music scholar Bill Malone has gone so far as to say that trucking songs account for the largest component of work songs in the country music catalog. For a style of music that has, since its commercial inception in the 1920s, drawn attention to the coal man, the steel drivin’ man, the railroad worker, and the cowboy, this certainly speaks volumes about the cultural attraction of the trucker in the American popular consciousness.” — Shane Hamilton
In 1976, the number one hit on the Billboard chart was "Convoy," a novelty song about a convoy of truck drivers evading speed traps and toll booths across America. The song inspired the 1978 action film Convoy, featuring a shirtless and defiant Kris Kristofferson screaming "Piss on your law!" After the film's release, thousands of independent truck drivers went on strike and participated in violent protests during the 1979 energy crisis (although similar strikes had occurred during the 1973 energy crisis)
The latter portion of the 20th century saw the decline of trucking culture, and the image of drivers generally moved to a more negative portrayal. As a result truck drivers were frequently portrayed as antagonists in movies.
Off-road trucks include standard, extra heavy-duty highway-legal trucks, typically outfitted with off-road features such as a front driving axle and special tires for applications such as logging and construction, and purpose-built off-road vehicles unconstrained by weight limits, such as the Liebherr T 282B mining truck.
The Department of Transportation (DOT) is the most common name for a government agency in North America devoted to transportation. The largest is the United States Department of Transportation, which oversees interstate travel and is a federal agency. All U.S. states, Canadian provinces, and many local agencies also have similar organizations and provide enforcement through DOT officers within their respective jurisdictions.
Some trailers are made for personal (or small business) use with practically any powered vehicle having an appropriate hitch, but some trailers are part of large trucks called semi-trailer trucks for transportation of cargo.
