. Go-karts come in all shapes and forms, from non-motorised models to high-performance racing karts. Karting is a type of racing in which a compact four-wheel unit called a go-kart is used. In the beginning, Art Ingels invented the first go-kart in Los Angeles in 1956.

Etymology

The exact origin of the term is unclear. One of the first appearances of the term is an 1885 painting by the Scottish artist Hugh Cameron RSA: "The Go-Cart". It is also unclear why the "C" was later changed to a "K".

s. High-performance electric go-karts for amusement parks and indoor tracks may have external electronic controls in the event of an accident or other hazards, in which the track attendant or the race referee can remotely slow down or stop all vehicles on the track via radio control. This external control can also be used to limit young riders to a slow operating speed, while a race consisting only of adults is permitted a higher speed. These controls can be applied to both electric and combustion-engine karts. In some countries, go-karts can be licensed for use on public roads often referred to as street tracks. Typically there are some restrictions; in the European Union, a go-kart modified for use on the road must be outfitted with headlights (high/low beam), tail lights, a horn, indicators, and an engine not exceeding .

Recreational, concession and indoor karts

Besides traditional kart racing, many commercial enterprises offer karts for rent, often called "recreational" or "concession" karts. The tracks can be indoor or outdoor. Karts are rented by sessions (usually from 10 to 30 minutes) or on a day basis. They use sturdy chassis complete with dedicated bodywork, providing driver safety. Most of these enterprises use an "Arrive and Drive" format which provides customers with all the safety gear (helmets, gloves and driver outfits) necessary, and allow them to show up anytime to race at a reasonable price, without the problem of having to own their own equipment and gear. Outdoor tracks can offer low-speed karts strictly for amusement (dedicated chassis equipped with low powered four-stroke engines or electric motors), or faster, more powerful karts, similar to a racing kart, powered by four-stroke engines up to and, more rarely, by 2-stroke engines, but designed to be more robust for rental use. Typically, outdoor tracks are also used for traditional kart races. Indoor kart tracks can be found in many large cities in different parts of the world. These tracks are often located in refurbished factories or warehouses, and are typically shorter than traditional outdoor tracks. Indoor karts are usually powered by a four-stroke gasoline engine producing anywhere from , or sometimes by an electric motor. Many tracks offer competitive races and leagues. At the top level, an Indoor Karting World Championship (IKWC) exists.
