The Ministry of Road Transport and Highways has issued a draft notification that would require electrified vehicles to be fitted with an Acoustic Vehicle Alerting System — a device that generates artificial sound in a vehicle that would otherwise be close to silent at low speed. The requirement is reported to apply to electrified vehicles in categories M and N, meeting the audibility requirements set out in AIS-173.
The dates are the part worth reading carefully, because they have been reported inconsistently. As drafted, the requirement takes effect from 1 October 2026 in the case of new models, and from 1 October 2027 in the case of existing models. Some coverage has led on the 2026 date and some on the 2027 date; both are correct, and they apply to different things.
This is the standard two-step used across Indian vehicle regulation. A manufacturer bringing a fresh model to approval has to meet the requirement from the earlier date, because the design is not yet frozen. A model already in production is given an additional year, because retooling an existing production vehicle takes longer than designing the requirement into a new one. Both dates concern vehicles being approved and built. Neither concerns a vehicle already registered and in use.
What the System Actually Does
An electric drivetrain is close to silent at the speeds where pedestrian risk is highest — car parks, residential lanes, the moment a vehicle pulls away from a junction. A petrol or diesel engine announces itself at those speeds almost by accident. An electric one does not.
That absence matters most to people who rely on hearing rather than sight to know a vehicle is approaching. A sound alert system closes the gap by producing a synthetic sound at low speed, typically fading out as road and tyre noise takes over at higher speeds. Several jurisdictions already require this, including the United States, Japan and members of the European Union, so the draft brings India's framework in line with an approach that has been settled elsewhere for some years rather than introducing a novel idea.
It is worth being precise about the status of the document. This is a draft. Draft notifications go out for comment, and they can be amended, delayed or issued in a different form than the one first circulated. Reporting a draft as though it were a notified rule is one of the more common errors in Indian auto coverage, and it produces exactly the sort of confusion that leads a used-car buyer to worry about something that does not apply to them.
Who This Reaches, and Who It Does Not
| Vehicle | Reached by the draft? | Why |
|---|---|---|
| A new electric model approved after the applicable date | Yes | The requirement attaches at approval and manufacture |
| An existing electric model still in production | Yes, from the later date | Given an additional year to comply |
| A used electric car already registered | No | Not a vehicle being approved or built; no retrofit requirement in the draft as reported |
| A petrol, diesel or CNG vehicle | No | The draft concerns electrified vehicles |
The third row is the one that matters to most readers of this site, and it is the row least likely to survive a headline. Nothing in the draft as reported requires a vehicle already on the road to be retrofitted. If you own an electric car registered in 2023, or you are looking at one this week, the draft does not create an obligation for you, and it does not render the car non-compliant on any date.
Rules of this kind reliably generate a secondary market in unnecessary services — workshops offering to "make your EV compliant", messages warning that an older electric car will fail some future check, quotes for fitting a device nobody has asked you to fit. Treat all of it with suspicion. If a requirement to retrofit existing vehicles is ever introduced, it will be notified properly and reported widely. Until then, nobody selling you a compliance service has a rule to point to.
What This Means for Used EV Buyers
The practical answer is that this changes nothing about what you should check, and quietly reinforces why the one check that matters is the one people skip.
On a used electric car, the registration date is doing an unusual amount of work. It establishes the true age of the vehicle regardless of the model year anyone quotes. It usually starts the clock on the manufacturer's battery warranty, which is the cover attached to the single most expensive component in the car. And it places the vehicle on one side or the other of every dated rule that comes along, including this one. That is three separate reasons to establish it from the record rather than from a conversation.
India's used electric market is also getting materially larger. Electric registrations set a monthly record in July 2026, and cars registered in the first big wave of private EV adoption are now reaching second and third owners. A bigger pool means more choice and also more variability — which makes the difference between a checked purchase and an assumed one wider than it was two years ago.
Check a Used EV Before You Pay
Registration date and true age, owner serial number, registration status, hypothecation against a loan and blacklist flags, pulled from the official record against any registration number. RC check Rs. 49, challan check Rs. 49, or both together for Rs. 79.
The record half of a used EV purchase is cheap, fast and conclusive. The battery half is neither, and no government record anywhere in India contains a field for battery state of health, remaining range or charging history — those have to be established physically. Our guide to what the VAHAN record shows about a used EV's battery, and what it cannot draws the line between the two and explains how to close the gap on the half the record does not cover.
There is a further wrinkle specific to electric vehicles that catches buyers who did everything else right: on some cars the battery is not owned outright but subscribed to separately, which the registration certificate will not tell you. We covered that trap in our piece on what the RC will not show on a battery-subscription EV, and it is worth reading before you agree a price on any electric car sold at a suspiciously attractive number.
What This Means for Sellers
If you are selling an electric car, the draft is not a reason to hurry and it is not a reason to discount. A vehicle already registered is not made non-compliant by a requirement that attaches to vehicles being built.
What is worth anticipating is the question. Buyers read the same headlines, and some will arrive believing their purchase needs a device fitted or will fail an inspection. Being able to answer that clearly — that the requirement as drafted applies to new and existing models at manufacture, not to registered vehicles — is the difference between a buyer who relaxes and a buyer who quietly walks away from a car they liked.
The rest is ordinary preparation, and it matters more on an electric car than most sellers expect. Confirm the hypothecation has actually been removed from the record if the loan has closed. Clear outstanding challans. Be accurate about the insurance and fitness position. And if there is a battery warranty with time left on it, establish the transfer conditions with the manufacturer in writing before you advertise, because a buyer who asks and gets a vague answer will assume the worst. A verified listing at Rs. 49 cross-checks the vehicle against the official record and carries a Verified badge, which settles the paperwork question before it becomes a negotiation.
The Short Version
A draft notification would require an Acoustic Vehicle Alerting System on electrified vehicles in categories M and N, meeting AIS-173, from 1 October 2026 for new models and 1 October 2027 for existing models. The purpose is pedestrian safety, particularly for people with visual impairments, and it brings India into line with the United States, Japan and the European Union.
It is a draft, both dates concern vehicles being approved and built, and nothing in it as reported requires a registered vehicle to be retrofitted. If you are buying a used electric car, the check that matters has not changed: establish the registration date and the legal position from the official record for Rs. 49, then deal with the battery as a separate, physical question. Anyone offering to sell you compliance for an existing EV is selling you something no rule has asked for.
Frequently Asked Questions
Nothing in the draft as reported requires a vehicle already registered and on the road to be retrofitted. Requirements of this kind operate on vehicles at the point they are approved and manufactured, which is why they are phrased around new models and existing models in production rather than around vehicles in use. A used electric car built and registered before the applicable date is outside the requirement. Since this is a draft rather than a notified final rule, confirm the position once it is finalised if it matters to a purchase you are making.
As reported, the draft applies from 1 October 2026 in the case of new models, and from 1 October 2027 in the case of existing models. The distinction is the ordinary one used in Indian vehicle regulation: a manufacturer introducing a fresh model has to meet the requirement sooner, while a model already in production is given an additional year to comply. Both dates concern vehicles being approved and built, not vehicles already registered.
It is reported to cover electrified vehicles in categories M and N. Category M covers vehicles used for carrying passengers, which includes electric cars and electric buses. Category N covers vehicles used for carrying goods, which includes electric trucks and goods carriers. The audibility requirements are to be met in line with AIS-173. Categories are defined in Indian vehicle regulation, so the practical question for any specific vehicle is which category it is registered under.
It is a system that generates an artificial sound in an electric or hybrid vehicle that would otherwise be close to silent at low speed. The purpose is pedestrian safety: a person crossing a road, and particularly a person with a visual impairment, relies partly on hearing a vehicle approach. An electric drivetrain removes most of that cue at the speeds where the risk is highest. Several countries including the United States, Japan and members of the European Union already require such systems, and India's draft would bring the domestic framework into line with that approach.
It does not add a new check, but it does reinforce the value of the one that already matters most. The registration date on a used electric vehicle already determines the warranty clock on the battery, the age of the car, and where it sits relative to any dated rule. Pull the vehicle's entry from the VAHAN database against its registration number to establish the registration date, owner serial number, registration status, hypothecation and blacklist position. On VahanBazaar an RC check costs Rs. 49 and a challan check costs Rs. 49, or both together for Rs. 79. The battery condition is a separate, physical investigation that no record covers.
