Automotive Industry Standard 140 (AIS 140) is a set of standards published by the Automotive Research Association of India (ARAI). It is used for vehicle tracking systems, camera surveillance systems, and emergency request buttons. The government has directed every state’s public transport department to make sure that all passenger-carrying buses conform to the AIS 140 guidelines by April 1, 2018.
