The Roads Policing Unit in Letterkenny detected a disqualified driver yesterday evening with the assistance of the Mobility App.
Gardai say the vehicle was seized and the driver will now face a Court appearance.
The Active Mobility App allows Gardaí to check a vehicle's history, tax, and NCT status.
It also allows Gardaí check the status of a driver's licence and Insurance and process fixed charge penalty notices in real time.
Gardai say the app allows them to work more efficiently and spend more time out in their communities.
