Street-legal , road-legal , or road-going , refers to a vehicle such as a car , motorcycle , or light truck that is equipped and licensed for use on public roads, being therefore roadworthy . This will require specific configurations of lighting, signal lights, and safety equipment. Some specialty vehicles that will not be operated on roads, therefore, do not need all the features of a street-legal vehicle; examples are a vehicle used only off-road (such as a sandrail ) that is trailered to its off-road operating area, and a racing car that is used only on closed race tracks and therefore does not need all the features of a street-legal vehicle. As well as motor vehicles, the street-legal distinction applies in some jurisdictions to track bicycles that lack street-legal brakes and lights. Street-legality rules can even affect racing helmets , which possess visual fields too narrow for use on an open road without the risk of missing a fast-moving vehicle.
35-767: The Ariel Atom is a road-legal high performance open-wheel car made by the British Ariel Motor Company based in Crewkerne , Somerset , England, and under license in North America by TMI Autotech, Inc. at Virginia International Raceway in Alton, Virginia. There have been eight Ariel Atom generations to date: Ariel Atom, Ariel Atom 2, Ariel Atom 3 (including the Ariel Atom 3 Mugen Limited Edition and Honda Racing Edition – of which only one
70-587: A consistent set of national criteria issued by Transport Canada for specific equipment required as part of a street-legal vehicle. In some provinces, the Highway Traffic Act is a matter of provincial jurisdiction; provinces with such an Act include Ontario , Manitoba, and Newfoundland and Labrador. Many but not all U.S.-model vehicles do qualify for import to Canada, but must meet requirements for items such as daytime running lights (standard on Canadian-market vehicles since 1991, but not required in
105-633: A few. Vehicles which do not fall into one of the standard SVA categories – for example a vehicle of right-hand drive – require enhanced SVA in addition to standard SVA inspections. The SVA is in the process of being replaced by the Individual Vehicle Approval (IVA). In the United States , the individual states have the authority to determine, by means of statutes and regulations , which types of vehicles are permitted on public streets, as
140-456: A function of police power . Vehicles that are considered street-legal in the U.S. include automobiles, trucks, and motorcycles. Some vehicles that are not generally sold for on-road driving – such as all-terrain vehicles (ATVs) and golf carts – can potentially be adapted for street use, if permitted by state law. Most requirements for automobiles are largely consistent between U.S. states. A notable exception
175-476: A host of design improvements and changes. The new car also features a thicker frame, separate seats and a revised intake. The car has been reviewed by Autocar and deliveries started at the start of June 2019. In 2020, Autocar selected the Ariel Atom 4 as Britain's Best Driver's Car. The Ariel Atom was unofficially used by Wrightspeed as the base of a one-off prototype called the Wrightspeed X1 , which

In 2005 Road & Track magazine published the results of a comprehensive test of a range of cars, from the Porsche 911 Carrera S , Ford GT , BMW M5 to the Caterham CSR 260 . The supercharged Ariel Atom 2 won the 0–161–0 km/h (0–100–0 mph) test by a clear margin at 10.88 seconds, ahead of the Caterham CSR 260 (11.41) and

To separate Ariel manufacturing from its thriving sublet manufacturing services, TMI started all Ariel brand manufacturing and marketing efforts under the Ariel North America name. In 2011, VIR started the VIR Cup in which specialty designed track dedicated Ariel Atoms would compete in a series of races. This specially designed Atom
280-563: A row and 27 points in the first three races of the season. The car was driven to 88 points with the team, with 5 podium positions also being scored. The car was updated to the TF105B for the 2005 Japanese Grand Prix . It was unique as it ran without a keel, and the suspension was mounted higher on the car than the TF105. It seemed to particularly suit Ralf Schumacher , as on its first outing, Ralf took pole at Suzuka , helped by his knowledge of
315-490: A small optional windscreen) and a drag coefficient of 0.40. The Atom began as a student project by Coventry University transport design student Niki Smart together with Simon Saunders, a senior transport design lecturer. After several sports car companies rejected his proposal, Saunders founded his own company in 1991 named Solocrest Ltd. to create the Atom, which was renamed in 1999 as Ariel Motor Company Ltd. Known then as

Common requirements for automobiles include structure (examples: hood ) and safety equipment (examples: headlamps and bumpers ). Common requirements for motorcycles include side view mirrors and a dedicated seat in order to transport a passenger. However, states vary widely on other equipment such as turn signals. Toyota TF105 The Toyota TF105
385-505: Is a proof of concept of the company's all-electric powertrain. In mid-2012, it was announced that for the first time in the UK, the Atom would have a dedicated single-make race series called Atom Cup. The series would feature on Jonathan Palmer 's MSVR programme of racing with eight race weekends featuring 16 races. The cars were 183 kW naturally aspirated, 3.5 chassis with an MSA approved welded roll bar protection system. The standard suspension

525-902: The British International Motor Show at the NEC in Birmingham in October 1996. The Atom suspension setup was tuned by the engineers at Lotus. Edmunds "Inside Line" noted that "anyone who has driven a selection of Lotus-tuned cars, such as the Lotus Elise , the Aston Martin Vanquish and the Opel Speedster , will notice a common feel or signature, and it's replicated in the Atom." The Atom's suspension derives from single seat racing cars and

Since August 2001, there have been two levels of SVA, those being 'standard' and 'enhanced'. The standard SVA is applied to vehicles such as left-hand drive vehicles, personally imported vehicles, amateur-built vehicles and armoured vehicles , to name
595-524: The fastest accelerating production car when initially released. On 23 January 2011, the Atom 500 set the lap record around the Top Gear test track , with a time of 1:15.1, making it the fastest road-legal car to go around the track – a record that stood for just over two years, until the Pagani Huayra completed a lap in 1:13.8 on 27 January 2013. The Ariel Atom 3.5R is the upgraded version of

Cars from other countries (such as the UK) typically do not qualify, as standards are too widely divergent from those in Canada. Requirements for manufacturing, registering, and operating motor vehicles in India are codified by the Central Motor Vehicles Rules (CMVR), as maintained by the Ministry of Road Transport and Highways. Street-legal two-, three-, and four-wheeled vehicles must comply with structure, safety equipment, and operating conditions in CMVR 93–125. In
