AIS 140: What the Standard Requires and Who It Applies To

AIS stands for Automotive Industry Standard. The AIS series is the body of technical standards prepared for the Indian automotive sector and adopted under the country's road transport rulemaking; 140 is the number of the standard dealing with intelligent transportation systems. So AIS 140 is not a law in its own right — it is a technical specification that regulation points at, which is why compliance questions almost always resolve into two separate questions: what does the standard require, and which vehicles has an authority required it for.

The core of it is the vehicle location tracking device: a certified unit that reports position at defined intervals, holds internal power and storage so it survives disconnection and network gaps, and transmits to a designated state backend control centre rather than solely to a private platform.

For passenger-carrying categories the standard adds emergency buttons, so that a passenger or driver can raise an alert that reaches the backend rather than only an operator's control room. Some categories also attract camera surveillance requirements. The applicable combination depends on the vehicle category, which is why the standard is better read as a menu of requirements applied selectively than as one uniform obligation.

The standard describes the technical requirement. Making it binding on a particular class of vehicle is done through notification by transport authorities, and those notifications have arrived at different times, with different scope and different enforcement intensity, across states. The result is a genuinely uneven picture in which two operators running similar vehicles in different states can face different obligations and different deadlines.

The practical consequence for a fleet running across state lines is that compliance is checked per registration state rather than assumed uniformly, and that procurement decisions should be made against the current notification rather than against what was true when the fleet last bought devices. Anyone reading this page as the basis for a compliance decision should verify the current position for the relevant state and vehicle category — that detail moves, and a standard summary is not a substitute for the notification in force.

Devices are tested against the standard by recognised testing agencies, and it is the device model that carries the certification. That leaves two gaps operators routinely fall into. A certified model bought from an uncertified reseller is still a certified model, but the fitment and backend provisioning may not have been done. And a certified model correctly fitted still needs the paperwork tying it to the vehicle to exist when a permit is issued or renewed.

In other words, certification is a necessary condition and nowhere near a sufficient one. The compliant state is a certified device, correctly fitted, provisioned to the right backend, with the fitment documentation to prove it.
