The Ministry of Road Transport and Highways has proposed mandatory Acoustic Vehicle Alerting Systems (AVAS) for all new electric cars, buses, and trucks from October 2026 and existing models from October 2027, to enhance pedestrian safety at low speeds (0–20 kmph).
Description:
| Aspect | Details |
| Definition | AVAS is a device installed in electric and hybrid vehicles that produces artificial sound cues to alert pedestrians and improve road safety. |
| Need | EVs are nearly silent at low speeds (no IC engine noise) → Risk to pedestrians → Artificial sound alerts necessary. |
| Applicability | All M & N category vehicles (cars, buses, trucks, e-rickshaws, e-carts). |
| Timeline | – New Models: Compliance from Oct 2026 – Existing Models: Compliance from Oct 2027 |
| Activation Range | Automatically active at 0–20 km/h (silent zone speed range). |
| Sound Design | Emits steady, low-volume artificial tone (not disturbing, just enough for awareness). |
| At Higher Speeds | Above 20 km/h, tyre + aerodynamic noise is sufficient → no AVAS required. |
