Motorists driving foreign vehicles illegally on Manx roads are to be targeted by police this summer.
Officers will use Automatic Number Plate Recognition (ANPR) technology to identify un-taxed vehicles with overseas number plates.
Vehicles transferred to the island must be re-registered with the Vehicle Test Centre within 12 weeks.
Home Affairs Minister Bill Malarkey told the House of Keys the trial will run until the end of the year.
If successful, the scheme could become a "permanent fixture," he added.
More than a dozen people driving un-taxed UK-registered vehicles were stopped by police during recent checks.
None had paid Manx car tax or registered their vehicle on the island.
