Road signs that know when a mobile phone is being used in a moving vehicle are being installed in Norfolk, in a bid to tackle usage behind the wheel.
The system, which can tell the difference between active phone calls and other activities based on the strength of a signal and how long it lasts, flashes up a red warning signal to drivers when it detects a call.
The technology cannot yet log number plates or be used to help catch offending drivers, but it is hoped it will act as a deterrent.
