Uganda Revenue Authority (URA) has seized 27 foreign registered vehicles thought to be operating in the country illegally.
"Under the Temporary Importation of Motor Vehicles and Export System (TEVIES), foreign vehicles, on URA's permission, are given a maximum of 90 days stay in the country [beyond that, they must be registered]," said a URA statement.
Others vehicles were found to have been smuggled into the country. The URA manager for enforcement operations, Julius N. Mponooka, said cars with local registration plates were also seized on realising that some of them were not registered with URA.
Some of them had changed their colour status without authorisation- something that alters their registration details.
"Owners of these vehicles, now parked at the URA headquarters in Nakawa, are expected to claim them with supporting documents in not more than 30 days," the URA statement quoted Mponooka as saying.
Section 214 of the East African Community Customs Management Act (ECCMA) 2005 grants authority to URA to auction vehicles that are not claimed within 30 days.
The operation, Catch-up, came out of the growing concern that many cars had foreign number plates which raised fear that they could have entered the country illegally.
Uganda is suspected to be a dumping ground for stolen cars - usually from neighbouring countries and as far as the UK.
