Police officers are riding on buses to catch drivers using their mobile phones.

Road Safety Officers from Hampshire and the Thames Valley are taking part in a joint operation, using the height of a bus as a vantage point to spot wrongdoing.

Those caught using a mobile phone while driving can get a fixed penalty notice.

The campaign is being supported by Kate Goldsmith who lost her daughter in a crash in August 2016.
