Vehicle inspection is a procedure mandated by national or subnational governments in many countries, in which a vehicle is inspected to ensure that it conforms to regulations governing safety, emissions, or both. Inspection can be required at various times, e.g., periodically or on the transfer of title to a vehicle. If required periodically, it is often termed periodic motor vehicle inspection; typical intervals are every two years and every year. When a vehicle passes inspection, often a sticker is placed on the vehicle's windshield or registration plate to simplify later controls, but in some countries—such as the Netherlands since 1994—this is no longer necessary. Most US inspection decals/stickers display the month's number and the year.
