India to Mandate EV Sound Alerts From October 2026: New Cars Must Hum at Low Speeds

New electric cars sold in India will have to make a sound. From October 2026, Acoustic Vehicle Alerting Systems (AVAS) become mandatory on fresh models, requiring EVs to emit an audible alert at low speeds so pedestrians, cyclists and the visually impaired can hear them coming.

The rule targets a simple problem. Electric motors are quiet, and below roughly 20-30 kmph there's little tyre or wind noise to give a car away. At a crawl through a market or a school lane, an EV can be on top of someone before they register it.

What AVAS actually does

AVAS is a small speaker system that generates a synthetic sound when the car is moving slowly. It kicks in at low speed and fades out as the vehicle picks up pace, by which point road and wind noise take over. The sound has to be loud enough to be heard over traffic but not so loud it becomes a nuisance.

The system is already standard in several markets. Europe made AVAS compulsory for new electric and hybrid vehicles years ago, and the underlying standard, UN Regulation 138, sets out how loud the alert must be and at what speeds it operates. India's rule follows that same logic, applied to a market where two-wheelers, pedestrians and handcarts share the same road space as cars.

Why low speed is the danger zone

Most pedestrian collisions happen at low speed, in dense traffic, near crossings and junctions. That's exactly where a silent EV is hardest to notice. A hum or whir gives people a split-second more to react.

For visually impaired pedestrians, the stakes are higher. They rely on engine sound to judge whether a vehicle is approaching and how fast. A quiet EV removes that cue entirely.

The practical questions

• Which models does the October 2026 deadline cover, and whether existing EVs already on the road will need retrofits.
• What sound level and speed range the Indian rule specifies, and how closely it tracks UN Regulation 138.
• Whether carmakers can choose their own alert tone or must use a standardised sound.

Carmakers selling in India already fit AVAS on some models, particularly those built for export markets. Scaling that to every new EV is a cost and engineering question, but not a new one. The hardware is cheap and the technology is mature.

The bigger shift is cultural. Indian roads are loud, and adding another sound to the mix will draw complaints from some drivers. Regulators will have to get the volume right: audible enough to warn, restrained enough not to add to the din.

For now the timeline is set. From October 2026, a new electric car in India won't just be quiet. It'll hum.
