We have set out guidelines to determine if a vehicle has been abandoned:
A vehicle must be left in the same place for 21 days before Inspectors will visit, to determine if the vehicle meets any other Abandoned vehicle criteria
There may be legitimate reasons why a car has been left somewhere, for example:
If the vehicle is parked where it is obstructing a private dropped crossing (i.e. outside a house) then a request needs to be made to Parking Enforcement who will check and then refer the issue for enforcement action to be taken.
If a vehicle is not currently taxed then it can be reported to the DVLA.
