What is an ATV?
ATV (all-terrain vehicle), also known as a LUV (light utility vehicle), a quad bike, or simply a quad, as defined by the ANSI (American National Standards Institute); is a vehicle that travels on low-pressure tires, with a seat that is balanced by the operator, along with handlebars for steering control.
As the name suggests, it is designed to handle a wider terrain than most other vehicles.
Therefore, although it is a street-legal vehicle in some countries, it is not street-legal within most states, regions, and provinces of the United States, Australia, or Canada.
By the current American National Standards Institute definition, ATVs are designed for a single operator, although some companies have developed ATVs designed for use by the operator and one passenger.
These ATVs are referred to as tandem ATVs. The rider sits on and works these vehicles like a motorcycle, but the extra wheels provide more stability at slower speeds.
Although most are provided with three or four, six-wheel models exist for specialized applications.
For example, multiple-user analogs with side-by-side seating are called UTVs (utility terrain vehicles ) or side-by-sides to distinguish vehicle classes. Both classes tend to have similar powertrain parts.
Engine sizes of ATVs currently for sale in the USA (as of 2008 products) range from 49 to 1,000 cc (3.0 to 61 cu in).
