Drag racing is a type of motor racing in which automobiles or motorcycles compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly 1⁄4 mi, with a shorter, 1,000 ft distance becoming increasingly popular, as it has become the standard for Top Fuel dragsters and Funny Cars, where some major bracket races and other sanctioning bodies have adopted it as the standard. The 1⁄8 mi is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s.
Traffic comprises pedestrians, vehicles, ridden or herded animals, trains, and other conveyances that use public ways (roads) for travel and transportation.
A chicane is a serpentine curve in a road, added by design rather than dictated by geography. Chicanes add extra turns and are used both in motor racing and on roads and streets to slow traffic for safety. For example, one form of chicane is a short, shallow S-shaped turn that requires the driver to turn slightly left and then slightly right to continue on the road, requiring the driver to reduce speed. The word chicane is derived from the French verb chicaner, which means "to create difficulties" or "to dispute pointlessly", "quibble", which is also the root of the English noun chicanery.
The numerous Formula One regulations, made and enforced by the FIA and later the FISA, have changed dramatically since the first Formula One World Championship in 1950. This article covers the current state of F1 technical and sporting regulations, as well as the history of the technical regulations since 1950.
The Trans-Am Series presented by Pirelli is a sports car racing series held in North America. Founded in 1966, it is sanctioned by the Sports Car Club of America (SCCA). Primarily based in the United States, the series competes on a variety of track types including road courses and street circuits. Trans-Am is split into the TA and TA2 classes for silhouette racing cars, while its production classes are the GT, SGT, and XGT.
In motorsports, a pit stop is a pause for refuelling, new tyres, repairs, mechanical adjustments, a driver change, as a penalty, or any combination of the above. These stops occur in an area called the pits, most commonly accessed via a pit lane which runs parallel to the start/finish straightaway of the track and is connected to it at each end. Along this lane is a row of garages outside which the work is done in a pit box. Pit stop work is carried out by the pit crew of up to twenty mechanics, depending on the series regulations, while the driver often waits in the vehicle.
Banger racing is a tarmac, dirt, shale and chalk track type of motorsport event popular in countries such as the United Kingdom, Ireland, Belgium and the Netherlands. Vehicles are raced against one another, with the winner being the first to the checkered flag after a set number of laps. Contact to damage an opponent's car is permitted and encouraged within the formula, with cars progressively becoming more damaged throughout an event. Races are held at an oval or tri-oval circuits that are up to 1⁄4 mile long; however, on certain occasions, races are held in a figure of eight configurations. Banger racing is often confused with stock car racing, although there are differences between the two, despite often racing at the same tracks.
In motorsport, a safety car, or a pace car, is an automobile which limits the speed of competing cars or motorcycles on a racetrack in the case of a caution period such as an obstruction on the track or bad weather. The aim of the safety car is to enable the clearance of any obstruction under safer conditions, especially for marshals and/or await more favourable track conditions weather-wise.
Ice racing is a form of racing that uses cars, motorcycles, snowmobiles, all-terrain vehicles, or other motorized vehicles. Ice racing takes place on frozen lakes or rivers, or on groomed frozen lots. As cold weather is a requirement for natural ice, it is usually found at higher latitudes in Canada, the northern United States, and in northern Europe, although limited indoor events are held in warmer climates, typically on ice hockey rinks. Tracks in North America vary from 1/4 mile to several mile-long circuits.
Street racing is typically an unsanctioned and illegal form of auto racing that occurs on a public road. Racing in the streets is considered an ancient hazard, as horse racing occurred on streets for centuries, and street racing in automobiles is likely as old as the automobile itself. It became especially prevalent during the heyday of hot rodding (60s), muscle cars (70s), Japanese imports (90s), and sports cars (2000s). Since then, it continues to be both popular and hazardous, with deaths of bystanders, passengers, and drivers occurring every year. In the United States, modern street racing traces its roots back to Woodward Avenue, Michigan, in the 1960s when the three main Detroit-based American car companies were producing high-powered performance cars. Since a private racing venue was not always available, street races would be held illegally on public roads.
Racing flags are traditionally used in auto racing and similar motorsports to indicate track condition and to communicate important messages to drivers. Typically, the starter, sometimes the grand marshal of a race, waves the flags atop a flag stand near the start/finish line. Track marshals are also stationed at observation posts along the race track in order to communicate both local and course-wide conditions to drivers. Alternatively, some race tracks employ lights to supplement the primary flag at the start/finish line.
Road signs in Sweden are regulated in Vägmärkesförordningen, VMF (2007:90), and are to be placed 2 metres from the road with the sign 1.6 m from the base for motorized roads. Except for route numbers, there are a maximum of three signs on a pole, with the most important sign at the top. All signs have a reflective layer added on selected parts of the sign as is custom in European countries; most larger signs also have their own illumination.
A rolling start is one of two modes of initiating or restarting an auto race; the other mode is the standing start. In a rolling start, the cars are ordered on the track and are led on a certain number of laps at a pre-determined safe speed by the safety car.
In North American auto racing, a green–white–checker finish (GWC) is a racing restart procedure one in which the race is restarted from a caution period with 2 laps remaining. When the race distance is extended to accommodate such a finish, it is also sometimes known as an overtime finish. The name alludes to three racing flags:
Motorsport marshals are mainly volunteer workers responsible for the safety of motor racing competitors. They are stationed at various points of danger around race tracks to assist them in case of any collisions, accidents or track problems. Marshals are also known as course workers, corner workers, corner crews, turn marshals, corner marshals, track safety workers, or rally marshals.
BriSCA Formula 1 Stock Cars is a class of single-seater stock-car-racing in the UK with custom-built cars, with races conducted on walled oval tracks of either shale or tarmac of approximately a quarter-mile in length. The cars are of an open wheel design. The cars may be of any horsepower and drivers can use any engine they choose, with Chevrolet based small or big block V8 engines being the most popular. The season runs from March through to November, with occasional meetings during Christmas time.
The National Association for Stock Car Auto Racing (NASCAR) makes and enforces numerous rules and regulations that transcend all racing series.
The 2003 Grand Prix motorcycle racing season was the 55th F.I.M. Road racing World Championship season. The season consisted of 16 races, beginning with the Japanese motorcycle Grand Prix on 6 April 2003 and ending with the Valencian Community motorcycle Grand Prix on 2 November.
The 24 Hours of Lemons, sometimes styled as "24 Hours of LeMons", "24 Hours of LeMONS", or "24 Hours of LEMONS", is a series of endurance races held on paved road race courses across the United States. The series holds the Guinness World Record for the "Most participants in one race".
