The UAE is moving fast towards clean and modern transport, with more electric and hybrid cars seen on the roads. These cars help the environment and provide safer transport by integrating various advanced features. However, they are very quiet when they move at low speed, which can pose safety risks for pedestrians. Car makers have added an important feature called the Acoustic Vehicle Alerting System (AVAS) to solve this issue.
What is an Acoustic Vehicle Alerting System
An Acoustic Vehicle Alerting System (AVAS) is a sound device installed in electric and hybrid cars that emits a loud warning sound when the vehicle moves at low speeds. It is also referred to as a pedestrian alarm, an acoustic warning system or a pedestrian safety system. The primary purpose of AVAS is to alert pedestrians and other road users to the presence of an approaching vehicle, thereby mitigating the safety risks for pedestrians.
How Does AVAS Work?
AVAS typically activates when a car travels below a certain threshold, usually around 20 km/h. The system generates a continuous, artificial sound that is distinct from the sounds of a conventional internal combustion engine.
This sound is designed to be noticeable without being overly intrusive or contributing to noise pollution. As the vehicle’s speed increases beyond the activation threshold, the AVAS usually deactivates, as tire and wind noise become more prominent, making the vehicle audible.
The Importance of AVAS
The Acoustic Vehicle Alerting System is now a key safety feature in some electric vehicles for sale in the UAE.
Pedestrian Protection
Electric and hybrid vehicles are often difficult to hear, especially when driving slowly. This creates a concern for pedestrians who rely on sound to judge the presence and movement of cars. AVAS reduces these risks by producing a clear, artificial sound that makes the vehicle audible. The sound is designed to rise in pitch as the vehicle accelerates, allowing people to understand its speed and direction.
Assistance for People of Determination
Sound cues are vital for people of determination in the UAE to ensure safe movement. Traditional vehicles naturally make engine noise, but electric cars are almost silent at low speeds. AVAS bridges this gap by offering consistent, predictable audio sounds that people of determination can rely on. These signals improve confidence when crossing roads or moving near traffic.
Enhanced Safety in Parking Areas
Car parks are high-risk spaces where pedestrians, including children and elderly people, move close to vehicles. Cars usually travel slowly in these areas, making electric vehicles almost silent. With AVAS, cars produce clear warning sounds when reversing or driving at low speeds, helping drivers and pedestrians remain aware of each other.

FAQs
At what speeds does AVAS system for electric vehicles normally operate?
AVAS usually operates when the vehicle is moving up to 20 km/h and when reversing, since higher speeds create natural tyre and wind noise.
Is AVAS maintenance-free or does it require servicing?
AVAS is generally maintenance-free but may need inspection during routine vehicle servicing to ensure it works correctly.
Does Acoustic warning system for EVs work in both forward and reverse gears?
Yes, AVAS activates in forward motion at low speeds and when reversing, which helps prevent accidents in car parks and narrow lanes.
Are motorcycles and scooters also fitted with AVAS?
Yes, some two-wheelers, such as mopeds and electric scooters in the UAE, are equipped with AVAS to make them audible in urban traffic.
The Acoustic Vehicle Alerting System is vital in the age of electric mobility. It supports safety and urban growth, ensuring quiet electric vehicles remain safe for all road users. Many drivers exploring electric mobility also check options for used cars for sale in the UAE. The market offers various vehicles that suit different budgets and needs.
