What compliance actually requires
School buses fall under AIS-140 in most states, which means a certified VLTD transmitting to the state backend and emergency panic buttons wired into the vehicle.
Fitting the device is only part of it. The device has to be registered against the vehicle on the state backend and actually transmitting, and a fitted-but-silent unit reads as non-compliant at a fitness check.
Beyond tracking, school transport carries additional norms covering speed, seating, identification, attendants and driver eligibility. These vary by state, so confirm with your RTO and school authority rather than assuming a national position. See AIS-140 compliance and the Supreme Court school bus guidelines.
