Police
Lancashire Constabulary 'Do It Online'
If residents witness regular incidents of nuisance or dangerous driving, I would urge them to contact the police directly either by the non-emergency telephone number: 101, or on the Lancashire Constabulary 'Do It Online' webpage, ideally, with a record of the registration numbers of the vehicles.
