What is the acoustic vehicle alerting system
 May 24, 2024|View:149

As electric and hybrid vehicles have become more prevalent on our roads, a new safety feature has emerged to help protect pedestrians - the Acoustic Vehicle Alerting System (AVAS).


AVAS is a system that generates an audible sound from electric and hybrid vehicles when traveling at low speeds. This helps alert pedestrians, cyclists, and others nearby that a vehicle is approaching, as electric motors tend to operate much more quietly than traditional internal combustion engines.


The sound emitted by AVAS is required by law to meet certain specifications. It must be audible between 500-5000 Hz and have a sound pressure level of 56 dB(A) or more as the vehicle travels at speeds up to 20 km/h (12 mph). Above 20 km/h, the natural noises from the vehicle become loud enough that the AVAS is no longer needed.

Acoustic Vehicle Alerting System

The goal of AVAS is to enhance road safety, especially in areas with high pedestrian traffic like urban centers, school zones, and residential neighborhoods. By providing an audible cue, AVAS helps blind, visually-impaired, and distracted pedestrians become aware of the approaching vehicle.


AVAS is now mandated for all new electric and hybrid vehicles sold in many countries around the world, including the United States, European Union, Japan, and China. As electric vehicle adoption continues to grow, this safety feature will become increasingly common on our roads.
