Vauxhall is introducing a dual-function camera on the new Insignia that not only reads speed limit and no-overtaking signs and displays them on the instrument panel, but also alerts drivers when they unintentionally veer out of their lane.

Known as Traffic Sign Recognition and Lane Departure Warning, Vauxhall said the two systems would improve driving safety, reduce stress and could prevent costly speeding tickets.

Hans Demant, managing director of GME Engineering, said: "These new features follow Vauxhall's philosophy of enhancing driving excitement by assisting drivers without reducing their level of control. That means the system gives drivers information, but it doesn't intervene."

The system, featuring traffic sign recognition and lane departure warning will be available as an option on the new Insignia, with other Vauxhall models benefiting from the system in future.
