AVAS Legislation & Regulation

The European Blind Union (EBU) has raised concerns about the risks posed by quiet transportation, particularly for the visually impaired. In response, the European Union has introduced UNECE Regulation No.138, which mandates that all electric and hybrid vehicles be equipped with an Acoustic Vehicle Alerting System (AVAS). Starting from 1 July 2021, if the exterior noise of a vehicle does not meet the specified overall levels with a margin of +3 dB, it must use AVAS in accordance with UNECE Regulation No. 138.01.

Similar electric car legislation regarding hybrid and electric vehicles exists in other countries:

• In the United States, FMVSS No. 141 requires the use of AVAS in hybrid and electric vehicles since September 1, 2020.
• In Japan, specific regulations are in place to address noise concerns related to electric and hybrid vehicles.
• China has its own regulations, known as GB/T 37153, that cover the use of AVAS in electric and hybrid vehicles.

These UN legislation and other regulations aim to ensure the safety of pedestrians, particularly those who are visually impaired, by making electric and hybrid vehicles more audible in various traffic situations.
