You can report vehicles causing an obstruction to Lincolnshire Police by calling 101.
Section 99 of the Road Traffic Regulation Act 1984 authorises the police to remove vehicles that are illegally, dangerously or obstructively parked whether or not they have been stolen.
It is not the responsibility of the Local Authority to deal with parking issues or vehicles parked in a dangerous position, unless the vehicle is in contravention of the parking restrictions (Controlled by way of a Traffic Regulation Order) and in this case should be passed onto Parking Services.
