A lorry that has been dubbed the UK's biggest undercover police vehicle is being used in Northamptonshire to catch out bad drivers.
Officers say their high up position in the cab helps them spot and photograph motorists breaking the law.
The truck is on loan from Highways England and police say drivers are not expecting to be observed committing a moving traffic offence by a lorry with two police officers in it.
Drivers have been spotted using their phones, texting, changing their music channels on their phone and rolling cigarettes. One lorry driver was seen eating a Pot Noodle.
