Background
Automotive Industry Standards (AIS) are technical standards developed by the Automotive Research Association of India (ARAI) under the aegis of the Ministry of Road Transport and Highways (MoRTH), Government of India. These standards form the technical backbone of the Central Motor Vehicles Rules, 1989 (CMVR) — notified under the Motor Vehicles Act, 1988 and provide detailed specifications, test procedures, approval requirements, and performance benchmarks that motor vehicles and their components must meet before being manufactured, imported, sold, or registered in India.
Applicability
AIS standards apply to all persons and entities involved in the manufacture, import, sale, distribution, and use of motor vehicles and their components in India. This includes vehicle manufacturers — who must ensure that all vehicles offered for sale comply with applicable AIS specifications and have obtained type-approval from the designated testing agency — component manufacturers and suppliers of safety-critical components, importers of motor vehicles and components, dealers offering vehicles or components for sale, and vehicle owners who retrofit or alter their vehicles. The standards apply across all vehicle categories — including two-wheelers, three-wheelers, four-wheelers (M1, M2, M3, N-category), trailers and semi-trailers, quadricycles, construction equipment vehicles (CEVs), earth-moving machinery, tractors, and specialised vehicles such as those carrying hazardous goods or equipped with hydrogen fuel cell systems. Conformity of Production (COP) obligations additionally apply to manufacturers to ensure that production-line vehicles continue to meet the same specifications as the type-approved model.
