The ministry has set mandatory timelines for automakers to comply with other Automotive Industry Standards (AIS), covering occupant protection in offset frontal and lateral collisions, protection of pedestrians and other vulnerable road users, and fitment of immobilisers. The requirements will come into effect from April 2027 onwards. In a notification, the ministry also made AIS-192 mandatory for Event Data Recorders (EDRs) installed in cars from Oct 2029.
