The latest and most talked about system – Volvo Collision Warning with Emergency Brake – also consists of a combination of radar and camera. When the system detects vehicles in front that are stationary or moving slowly, the driver is alerted by sound and light signals. If there is no reaction from the driver then the system brakes itself – at first gently, then with full force until the truck has stopped completely and has avoided the collision. The so-called Lane Keeping Support, which alerts with a buzzing sound if the driver inadvertently crosses a road marking is a Volvo system that already meets statutory requirements. Yet despite the advances in technological developments, it is not the complete answer to the road safety issue. "We must be humble in acknowledging that road traffic safety is not all about technology, it is also a social issue." says Carl Johan Almqvist, Volvo Trucks' Traffic and Product Safety Director.
