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 shouldbe mountedto 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).
“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

As the American Interstate Highway System began to expand in the 1950's, the trucking industry began to take over a large market share. That is, a large share of the transportation of goods throughout the country. Before this era, trains hadbeen reliedon to transport the bulk of the goods cross country or state to state.The Interstate Highway System was influential as it allows for merchandise to travel door to door with ease.Since then, truckload carriers have taken advantage of the interstate system, especially when performing a long distance move.Typically, they bring the merchandise from one distribution center of the country to another part of the country.The increase in truckload freight transportation has reduced the time it takes to transport the goods.Whether the freightwas manufacturedor produced for the different areasinternationally, the time it takes to transport goods has decreased dramatically.
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.Howeverin Canada, the term is mostcommonlyused, 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 cannotbe determinedaround the entire loop.
The decade of the 70's in the United States was a memorable one, especially for the notion of truck driving. This seemed todramaticallyincrease popularity among trucker culture.Throughout this era, and even in today's society, truck driversare romanticizedas modern-day cowboys and outlaws.These stereotypes were due to their use of Citizens Band (CB) radios to swap information with other drivers. Informationregardingthe locations of police officers and transportation authorities. The general public took an interest in the truckers 'way of life' as well. Both drivers and the public took interest in plaid shirts, trucker hats, CB radios, and CB slang.
