AVAS Sound Alert System: India is taking a significant step toward enhancing road safety with the Ministry of Road Transport and Highways (MoRTH) proposing the mandatory implementation of the Acoustic Vehicle Alerting System (AVAS) for electric vehicles (EVs). As of September 2025, this draft regulation aims to ensure that the quiet nature of electric vehicles does not compromise the safety of pedestrians and other road users.
What is AVAS, and why is it Important?
AVAS is a safety technology that uses external speakers to generate a sound when an EV is in motion, especially at low speeds (below 20 km/h). Electric vehicles are nearly silent at these speeds, which can increase the risk for pedestrians, particularly those who are visually impaired. Studies indicate that the absence of engine noise makes it harder for pedestrians to detect approaching EVs, potentially raising accident risks. By producing an artificial sound, AVAS alerts pedestrians and other road users, enhancing overall road safety.
Implementation Timeline
The proposed regulation outlines a phased approach for AVAS implementation:
- October 1, 2026: All new models of electric passenger vehicles (Category M) and electric goods vehicles (Category N) must be equipped with AVAS.
- October 1, 2027: All existing models in production under these categories must also comply with AVAS requirements.
This phased approach ensures manufacturers have adequate time to adapt their vehicles and align with the upcoming safety norms.
Scope of the Mandate
The AVAS mandate applies specifically to:
- Category M: Electric cars and buses primarily used for passenger transport.
- Category N: Electric trucks and goods vehicles.
Currently, electric two-wheelers, three-wheelers, and e-rickshaws are not included in the initial draft of the regulation, though future amendments may expand the scope.
Compliance Standards
All AVAS-equipped vehicles must meet the audibility standards specified under the AIS-173 protocol, which sets the minimum and maximum sound levels to ensure effectiveness without creating unnecessary noise pollution. Some EV models in India already feature AVAS, so this regulation will standardize the safety feature across all eligible vehicles.
International and Indian Context
This move aligns India with global safety practices. Countries such as the United States, Japan, and European nations already mandate similar alerting systems for electric vehicles. By adopting AVAS, India is ensuring that its EV safety standards meet international norms while addressing local traffic safety challenges.
Supporting EV Growth
Beyond safety, the Indian government is actively promoting electric mobility. Under the PM E-DRIVE scheme, India plans to install 72,300 public EV charging stations with a ₹2,000 crore budget. BHEL has been appointed as the Project Implementation Agency, and the funding will be released in stages based on performance.
Conclusion
As electric vehicles become increasingly common on Indian roads, AVAS Sound Alert System will play a crucial role in safeguarding pedestrians and other vulnerable road users. The phased implementation by 2026-2027 reflects a balanced approach, supporting both industry adaptation and public safety. With AVAS and expanded charging infrastructure, India is accelerating its EV adoption while prioritizing a safer, smarter mobility ecosystem.
