The rapid adoption of electric vehicles (EVs) has been reshaping the global automotive industry. With governments pushing for greener mobility, EVs are set to dominate roads in the coming decades. However, the very feature that makes them unique—silent operation—has also raised significant safety concerns. Pedestrians, cyclists, and especially visually impaired individuals often find it difficult to detect approaching EVs due to their near-silent motors.
To address this issue, the Indian government has proposed a mandatory sound alert system for all electric vehicles starting from October 2027. The move aims to improve road safety while maintaining the environmental advantages of EVs. This initiative aligns with global practices, as similar regulations have already been introduced in the US, EU, and Japan.
This article explores the proposed regulation in detail, its implications for automakers, safety benefits, challenges, and how it could shape India’s EV future.
Why a Sound Alert System for EVs?
The Silent Challenge of Electric Vehicles
Unlike traditional internal combustion engine (ICE) vehicles that produce engine noise, EVs run almost silently at low speeds. While this is considered a comfort feature for passengers, it poses risks for pedestrians. In busy urban areas, where people often rely on hearing to detect vehicles, the absence of noise can lead to accidents.
Pedestrian Safety Concerns
- Visually impaired individuals rely heavily on auditory cues for navigation. A noiseless EV can pass unnoticed, increasing accident risks.
- Children and elderly pedestrians may also fail to detect approaching vehicles in silent traffic environments.
- Cyclists and two-wheeler riders often share roads with cars, and the lack of sound cues reduces reaction time.
Global Accident Data
- Studies in the US by the National Highway Traffic Safety Administration (NHTSA) revealed that EVs and hybrid vehicles are 37% more likely to be involved in pedestrian accidents at low speeds compared to ICE vehicles.
- In the UK, several road safety groups have raised alarms over “silent danger” from EVs, particularly in urban zones.
Given these safety issues, the Indian government’s move is both timely and essential.

The Proposed Indian Regulation
Timeline and Enforcement
- Effective Date: October 2027.
- Scope: Applies to all categories of electric vehicles, including two-wheelers, three-wheelers, passenger cars, and commercial EVs.
- Requirement: Vehicles must be equipped with an Acoustic Vehicle Alerting System (AVAS) that generates artificial sound when operating at low speeds.
Acoustic Vehicle Alerting System (AVAS)
The AVAS is a safety device that produces a minimum level of external sound to alert pedestrians of an approaching EV.
- Activation Speed: Typically under 20 km/h (city speed limits).
- Sound Design: Must be distinct enough to be heard but not cause noise pollution.
- Standardisation: Likely to follow global benchmarks (UNECE Regulation No. 138 and US FMVSS 141 standards).
Indian Context
- The Ministry of Road Transport and Highways (MoRTH) has been evaluating international safety standards.
- The government is consulting with automotive manufacturers and industry experts to finalise the technical requirements.
Global Precedents in Sound Alert Systems
India is not the first to propose such regulations. Many countries have already enforced them:
- United States
- The Pedestrian Safety Enhancement Act (2010) mandated that all hybrid and EVs must emit artificial sounds.
- By September 2020, NHTSA required compliance for all new EVs.
- The Pedestrian Safety Enhancement Act (2010) mandated that all hybrid and EVs must emit artificial sounds.
- European Union
- Since July 2019, all new EVs in Europe must be fitted with AVAS.
- Vehicles must produce sounds up to 20 km/h and during reversing.
- Since July 2019, all new EVs in Europe must be fitted with AVAS.
- Japan
- Japan mandated warning sounds for EVs as early as 2010, setting the trend for global adoption.
- Japan mandated warning sounds for EVs as early as 2010, setting the trend for global adoption.
- China
- China, the largest EV market, has also implemented AVAS requirements, ensuring both domestic and export vehicles comply.
By mandating AVAS from 2027, India aligns itself with these global safety standards.
Benefits of the Proposed System
1. Enhanced Road Safety
The primary goal is pedestrian safety. The artificial sound alerts people, reducing the risk of silent accidents in urban traffic.
2. Inclusive Mobility
Visually impaired individuals will particularly benefit. Organisations advocating for disability rights have long pushed for this regulation.
3. International Standardisation
Indian EVs will be more compliant with global export standards, boosting the country’s automotive industry.
4. Increased Public Confidence in EVs
By addressing safety concerns, the government can encourage hesitant consumers to adopt EVs.
Challenges and Concerns
1. Noise Pollution Risks
While the regulation aims to increase safety, there are concerns about additional noise pollution in already congested cities. Ensuring the AVAS sound is distinct but not disruptive will be critical.
2. Cost Implications for Automakers
Installing AVAS in every EV will increase production costs. Manufacturers must balance compliance with affordability.
3. Technical Standardisation
- What kind of sound should EVs emit?
- Should it mimic engine noise or be a unique tone?
- How loud should it be in different environments?
These questions need careful evaluation.
4. Implementation in Two-Wheelers and Three-Wheelers
India’s EV market is dominated by scooters, e-rickshaws, and three-wheelers. Developing low-cost AVAS systems suitable for these vehicles is a challenge.
