Dozens of motorists in Leicestershire have been caught breaking the law, by police officers patrolling the county in an unmarked HGV.

It鈥檚 all part of Operation Tramline, which aims to crackdown on drivers using their mobile phone, not wearing a seatbelt, or being under the influence of drink or drugs. During each day of the campaign, officers stopped drivers several times an hour.

Helen Astle went out on the road with them, and Ady Dayman spoke to Police and Road Safety Expert Jonathan Clarkson.
