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). United States 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 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 is California emission control, which has traditionally been more strict than that in other states. 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.
