Mobile phone detectors are to be used by police to find drivers using devices at the wheel.
The Thames Valley and Hampshire forces are rolling out the technology to
show when motorists are using their phones.
A sign will flash at the driver telling them to stop using their mobile -
but the detectors cannot tell if it is a driver or passenger using the phone.
The detector picks up 2G, 3G and 4G signals and will therefore flash to
alert people in cars who are using phones to call, text or data.
If people are using a Bluetooth hands-free device, the detector will
recognise this and not flash.

If it stops just one death, it has to be a good thing.
Have to remember phones talk to base by itself for location regardless.
