An all-terrain vehicle or ATV for short is defined by the American National Standards Institute (ANSI) as a vehicle that travels on low pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. ATVs were made in the United States a decade before 3- and 4-wheeled vehicles were introduced by Honda and other Japanese companies. During the 1960s numerous manufacturers offered similar small off-road vehicles that were designed to float and were capable of traversing swamps, ponds and streams, as well as dry land. Typically constructed from a hard plastic or fiberglass "tub", they usually had six wheels?all driven?with low pressure (around 3 PSI) balloon tires, no suspension (other than what the tires offered) and skid-steer steering. These early amphibious models were the original all-terrain vehicles?or ATVs. Contrary to today's ANSI definition of an ATV, they were intended for multiple riders sitting inside, and would usually have a steering wheel or control stick rather than motorcycle-type handle bars as stipulated in the current definition.[citation needed] Since the advent of three- and four-wheeled straddled ATVs, these have more or less 'taken over' the term, leaving aside the 6x6 and 8x8 floating variety, now mostly known as Amphibious ATVs (AATV).
