India’s final Acoustic Vehicle Alerting System (AVAS) rule now applies to new electrified M and N vehicle models from 1 Oct 2026. The change is meant to make quiet electric vehicles easier for pedestrians to detect, while existing models have until 1 Oct 2027 to meet the requirement.
Key takeaways
- The confirmed requirement comes from the Central Motor Vehicles (01st Amendment) Rules, 2026, notified through Gazette notification G.S.R. 07(E) on 2 Jan 2026.
- New electrified vehicles in categories M and N must use an AVAS meeting the audibility requirements of AIS-173 from 1 Oct 2026.
- Existing models get a separate compliance date of 1 Oct 2027; the rule does not mean every vehicle on the road must be changed immediately.
- For buyers, the practical check is whether a particular vehicle is covered as a new model or an existing model, and how its alert system operates at low speed and in reverse.

What the AVAS rule changes
The Gazette’s final amendment adds an AVAS requirement to Rule 120 of the Central Motor Vehicles Rules, 1989. It says electrified vehicles in categories M and N must be fitted with a system that meets the audibility requirements specified in AIS-173. The date for new models is 1 Oct 2026, while the date for existing models is 1 Oct 2027.
This is a confirmed vehicle-safety requirement, not a subsidy, price cut or charging-policy change. It affects how covered vehicles are designed and approved. It does not set a new purchase price, change a vehicle’s certified range or create a new toll or fuel charge for drivers.
| Vehicle status | Compliance date | What it means |
|---|---|---|
| New electrified M and N models | 1 Oct 2026 | AVAS must meet the notified AIS-173 audibility requirements. |
| Existing electrified M and N models | 1 Oct 2027 | Manufacturers have additional time under the final rule. |
The dates and categories above come from G.S.R. 07(E). The Economic Times and Times of India had also reported the October implementation timeline when the Ministry of Road Transport and Highways’ draft was discussed; the Gazette is the controlling primary source for the final rule.
What AVAS does on an electric vehicle
Electric vehicles are much quieter than conventional vehicles at low speeds because there is no engine sound in the usual sense. AVAS uses an external speaker or speakers to create an audible warning so a pedestrian, cyclist or other road user can notice an approaching vehicle before it is close.
The Times of India describes the system as a speed-linked sound that is especially useful during low-speed movement and reversing. The aim is not to make an EV sound like a petrol or diesel vehicle at all times. It is a safety layer for situations in which tyre and wind noise may not give a nearby pedestrian enough warning.
Which vehicles and buyers are affected
Category M covers vehicles used to carry passengers, including cars and buses, while category N covers goods vehicles such as trucks and other cargo carriers. That distinction matters because the final provision is written for electrified M and N vehicles; it is not a blanket statement that every electric two-wheeler has the same deadline.
The rule is most relevant when a manufacturer introduces a new electric car, bus or goods vehicle model after the new-model date. A vehicle that is already treated as an existing model is covered by the later date in the notification. Buyers should therefore avoid assuming that the calendar date alone tells them whether a particular variant complies.
What EV buyers should check now
For a vehicle being considered after the new-model deadline, ask the manufacturer or dealer whether it is classified as a new model for the AVAS rule and whether its compliance documentation references AIS-173. The owner’s manual should explain when the sound operates, where the exterior speaker is located and whether the warning changes with vehicle speed or reverse selection.
A short demonstration is useful because the safety feature is experienced outside the cabin. Buyers can listen from the side of the vehicle, check that the alert is clear without being unnecessarily intrusive and understand what the system does before comparing vehicles. This is a safety and compliance check, not a claim that one sound design is better than another.
AVAS is only one part of the ownership picture. Drivers planning regular inter-city use can check the state-wise EV charging directory for the availability of charging points on their important routes. For a running-cost comparison, the fuel cost calculator can benchmark a comparable petrol trip against the distance a buyer normally drives; electricity tariffs and public-charging prices still need to be added separately.
For longer journeys, the road-trip planner can help map distance and stops. That matters because a safety feature such as AVAS improves awareness around the vehicle, but it does not replace route planning, charging stops or normal pedestrian-safety precautions.
What changes now, and what does not
From the new-model compliance date, manufacturers bringing covered electrified M and N models into the market must account for the notified AVAS audibility standard. Existing models do not face the same immediate deadline because the rule gives them until 1 Oct 2027.
For consumers, there is no published AVAS-related surcharge, incentive or change to the official range figure in the notification. The immediate buyer takeaway is to treat AVAS as a safety and compliance item: confirm the model’s status, understand the alert behaviour and then compare charging access, route fit and total running cost.
