Off-road bikers riding illegally and anti-socially in Amble are being targeted by Northumberland County Council and Northumbria Police.
It follows concerns from residents about bikes being ridden on paths, parkland and grassed areas, which has been a seasonal issue in the past.
The Safer Northumberland Partnership is working to ensure bikes are used sensibly and safely.
Signs have been put up at hotspots in the area warning would-be riders about the law and the potential consequences of illegal riding.
Police have already taken action through extra patrols and have used video and photographic evidence to target offenders.
Anyone with details about the inappropriate use of off-road bikes can call police on 101 or 0845 6006400, although this is not a round-the-clock service.
