A blitz on untaxed and abandoned cars got underway in Pembrokeshire on Monday.
The two-week crackdown, condenamed Operation Cubit, is the result of a partnership between Pembrokeshire County Council, Dyfed-Powys Police and the DVLA.
To mark the start of the initiative, a 38-ton mobile crusher was in operation in the Safeway store car park in Haverfordwest to show owners of unlicensed and abandoned cars what could happen to their vehicles when identified.
The DVLA estimate there are around 5,000 untaxed and abandoned cars in Pembrokeshire alone.
At the demonstration, four of these cars were lifted by a claw into the crusher. After being squashed into a cube, they were lowered by the claw onto a tarpaulin to be collected later and taken for disposal.
Said county councillor Brian Hall, cabinet member for environment and transportation: "All the agencies involved are determined to get to grips with this problem.
"We hope the crusher will provide a salutary reminder to people that leaving untaxed and abandoned vehicles littering our streets and countryside will not be tolerated."
John Moore, DVLA's enforcement manager, said: "We are delighted to be working in partnership with the local council, police and fire service to tidy up the streets of Pembrokeshire.
"This type of operation demonstrates what can be achieved in dealing with this ever-increasing environmental problem. Many unlicensed vehicles do not have a MoT, are uninsured or are committing other road safety offences."
