CUSTOMS and Excise officers, in collaboration with Local and National police, clamped down on foreign-plated cars yesterday, setting up control points at the arrivals area of Son Sant Joan airport.
The controls started early in the morning and continued until shortly after noon.
During that time, 40 drivers were asked to show the cars' documents, and 20 of the vehicles were taken to the municipal pound.
Under current legislation, foreign-plated vehicles used by residents in Spain must be registered in this country within a maximum of 30 days.
The Customs and Excise department is in charge of inspection and control to ensure the car owners pay their taxes and can be localised if fines are issued.
The Local Police make sure that the drivers have the documents -- the MOT, roads tax and insurance -- in order.
Most of the vehicles impounded yesterday had German registration plates, but there were also cars from Poland, England and France.
Last year, the Customs and Excise impounded about 100 cars and boats in Majorca.
