Four vehicles have been seized by Gardaí from the Milford Roads Policing Unit since Thursday.
One was seized in the Newmills area for having no tax, insurance or NCT, and the driver was disqualified.
In Carrigart, a vehicle had taken off from Gardaí at high speed but was later intercepted. It was found to have no tax, insurance or NCT.
The third car, which also had no tax, insurance or NCT, was in Rathmullan and was seized.
They also seized a car this morning in the Letterkenny area as it had no tax, NCT or insurance and the two front tyres were dangerously worn.
Court proceedings will follow, and Fixed Charge Penalty Notices will be issued.
