Acoustic Alert System for EVs: India’s Next Move

October 2025 brings a new step for electric vehicles in India. The government has outlined plans to make acoustic alert systems in EVs — also called acoustic-vehicle-alerting-systems (AVAS) — a standard feature. The move comes as part of efforts to improve road safety for pedestrians, cyclists, and other vulnerable road users.

What Is an Acoustic Alert System?

Unlike traditional cars, electric vehicles are quiet at low speeds. While this is pleasant for drivers, it creates risks for people who rely on sound cues to sense approaching traffic. An acoustic alert system adds an artificial sound below 20 km/h and during reversing, making EVs easier to detect without being intrusive.

Design & Features

The system usually includes small external speakers. The sound changes with speed, becoming louder or sharper as the car accelerates. Premium versions may allow subtle customization, while budget EVs will use fixed tones. Most systems turn off automatically above 20 km/h when natural road noise takes over.

Impact on Safety

Studies show that low-speed EV collisions with pedestrians are more common because of the lack of sound. With AVAS in place, India aims to reduce such incidents. From October 2026, new passenger and goods EVs must include it, and by October 2027 all existing models must comply. Two- and three-wheelers are currently excluded.

EV Range & Cost

Since the alert system draws very little power, the effect on EV mileage or range is negligible. The added cost is also minimal, making it a practical safety addition for manufacturers and buyers alike.

Review & Outlook

Drivers will barely notice the system once installed, but pedestrians and cyclists will. That’s its value — it works quietly in the background. With India plans mandatory-acoustic vehicle alerting system in all electric vehicles by 2027, the country is aligning with global EV safety practices. It’s a change that could redefine how future EVs are designed and experienced.
