Drivers using the "wearable computer" device Google Glass at the wheel will fall foul of the law, the government has warned.
Worn like spectacles, Google Glass has a small screen just above the right eye and users can take a picture, record a video and read messages. The device is expected to go on sale next year.
In March of this year, Google picked 8,000 people from the USA to begin testing the technology, but the Department for Transport warned today that when the devices arrive in the UK anyone using them while driving could be prosecuted for careless driving.
A statement said: "It is important that drivers give their full attention when they are behind the wheel and do not behave in a way that stops them from observing what is happening on the road.
"A range of offences and penalties already exist to tackle those drivers who do not pay proper attention to the road, including careless driving which will soon become a fixed penalty offence.
"We are aware of the impending rollout of Google Glass and are in discussion with the police to ensure that individuals do not use this technology while driving."
