How does it work?

How does it work?

In most cases, when the ACN sensor detects either that an air bag has deployed or there’s been a dramatic and sudden deceleration, the system automatically connects to an operator, who will then be able to communicate with passengers in the vehicle after a crash. The operator is also able to collect basic information from the vehicle, without passenger input, to provide to emergency responders so they can easily locate and reach the scene of the crash.

What are the benefits of ACN systems?

Automatic crash notification systems can reduce death and disability by decreasing the time it takes for emergency medical services to arrive at a crash scene and transport victims to a hospital. More lives can be saved and the severity of injuries reduced if a crash victim receives medical care as soon as possible, particularly within the first hour following a crash. ACN is especially beneficial to crash victims in rural areas, where there are typically fewer or no witnesses to call emergency responders.
