Police arrest 30 and seize 417 vehicles in operation
Wales' biggest police clamp down on illegal drivers led to 417 vehicle seizures and 30 arrests over two weeks.
The crackdown involved all four of Wales' police forces.
Officers were targeting people driving while disqualified, driving with no insurance or driving without a valid licence.
They used Automatic Number Plate Recognition (ANPR) technology and worked with colleagues at the Motor Insurance Bureau and DVLA.
Across Wales, 30 people were arrested for driving whilst disqualified and 453 were caught for driving licence and insurance offences.
Gwent Police seized the most number of vehicles, 152, with North Wales Police next at 117 vehicle seizures during the period between October and November. South Wales Police seized 81 vehicles and Dyfed-Powys Police seized 67.
Gwent Police also found the most number of people, 135, behind the wheel with no driving insurance.
Across Wales 106 people were found to be driving with no driving licence.
The Commercial Vehicle Unit also dealt with 21 incidents of drivers' hours offences involving heavy goods vehicles. As a result of the arrests in north Wales, officers are now pursuing other lines of inquiry for other offences such as burglary.
"This campaign was about denying criminals the use of the roads, saving the ordinary driver from higher insurance premiums and reducing road casualties," said North Wales Police assistant chief constable Gareth Pritchard.
"Although the two-week enforcement period has ended, we will continue to target those who flout the law and endanger the lives of other road users and we will continue to work closely with other agencies such as the Motor Insurance Bureau and DVLA to target illegal drivers.
"There has been public support for this approach, and together we can help make our roads safer for all."
Sue Storch chair of Road Safety Wales and a Dyfed-Powys Police road safety officer, said: "It is disappointing that some drivers choose to ignore the law by driving illegally.
"However, throughout Wales it is excellent news that police seized over 400 vehicles from illegal drivers during the campaign."
