A POLICE blitz on Huddersfield's roads led to arrests and cars being seized.
Officers used computers in a couple of patrol cars linked directly to the Police National Computer and police intelligence systems.
The Automatic Number Plate Recognition Scheme computer scans number plates of passing cars.
It immediately alerts officers to any vehicles that are entered on computer as being linked to crime, untaxed or uninsured.
The hub of yesterday's activity was at Bradford Road between Hillhouse and Fartown.
Two drivers were arrested - one as a banned motorist and the other for driving document offences.
Eight cars were seized by police because their drivers were suspected of not being insured or not having the correct driving licence.
They will now have to pay a £105 fee to get their vehicles back and prove they are insured. One stolen car was also recovered during the operation.
Five vehicles were immediately banned from the road because they had serious mechanical defects which included bald tyres and heavily tinted windows. Eleven other motorists were given a few days to fix less serious faults on their vehicles.
These checks were carried out by officials from the Government's Vehicle and Operating Services Agency.
Driver and Vehicle Licensing Agency officers warned 11 drivers their number plates did not conform with regulations - such as numbers or letters being too close together.
Sgt Danny Groiser, of Huddersfield traffic police, said: "The day was all about catching people who make our roads more dangerous places to be."
