Operated Vehicles. The test agencies carry out type approval certification trials on the
vehicles and components submitted by vehicle/kit manufacturers/kit suppliers. Type
approval certification trials basically involve testing and evaluation of vehicles and
components for performance and safety and installation check on the vehicle. If the
vehicle meets the type approval norms and prescribed testing for components, type
approval certificate is awarded to the vehicle/kit manufacturers/kit suppliers and the
vehicle/kit manufacturers/kit suppliers are supposed to manufacture and market the
vehicles fitted with kits conforming to those specifications. Necessary owner’s manual,
