A VAN was seized during a police operation checking for illegal vehicles.
Working alongside VOSA and HM Customs, officers from Halifax Central neighbourhood policing team stopped scores of cars on Huddersfield Road in Halifax on Monday.
They carried out checks including vehicle defects, documentation and fuel dipping.
The Ford Transit van was seized after a dip sampling showed it was running on illegal red diesel. The owner was fined £500 and the vehicle could now be crushed.
Officers also issued five fixed penalty notices and 11 other drivers were reported by VOSA for various vehicle defects.
Police say the findings mean they are likely to repeat the operation.
