Motor Vehicle Standards
Many countries have legal requirements for the minimum safety standards of vehicles.
This means that all new vehicles and all vehicles that are still on the road must meet this minimum set of safety standards to be driven legally. Many countries also require that vehicles are tested by trained inspectors at regular intervals to make sure that they continue to meet these standards (Treatments\Safer Vehicles\Vehicle Roadworthiness).
Motor vehicle standards cover requirements such as (Australian Design Rules, USA Federal motor vehicle safety standards and regulations)
The standards also go beyond what is required to make a vehicle safe to drive. For example, many countries also have minimum standards of crashworthiness. This includes things such as how resistant the vehicle is to having its roof crushed, whether the side is able to resist side impact and the quality of the safety glass (USA Federal motor vehicle safety standards and regulations).
