QuestionA 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.

QuestionTrailer 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.


In the United States, commercial truck classificationis fixed byeach vehicle's gross vehicle weight rating (GVWR). There are 8 commercial truck classes, ranging between 1 and 8.Trucks are also classified in a more broad way by the DOT's Federal Highway Administration (FHWA). The FHWA groups them together, determining classes 1-3 as light duty, 4-6 as medium duty, and 7-8 as heavy duty.The United States Environmental Protection Agency has its own separate system of emission classifications for commercial trucks.Similarly, the United States Census Bureau had assigned classifications of its own in its now-discontinued Vehicle Inventory and Use Survey (TIUS,formerlyknown as the Truck Inventory and Use Survey).

QuestionThroughout the United States, bypass routes are a special type of route mostcommonlyused on an alternative routing of a highway around a town.Specificallywhen the main route of the highway goes through the town.Originally, these routeswere designatedas "truck routes" as a means to divert trucking traffic away from towns.However, this name was later changed by AASHTO in 1959 to what we now call a "bypass".Many "truck routes" continue to remain regardless that the mainline of the highway prohibits trucks.

QuestionThe 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.
