Gardai have reiterated their call to motorists this Bank Holiday to never drink and drive.
The warning comes as Gardai in Buncrana detected a car travelling at 168kmph in an 80kmph zone.
The driver of the vehicle was subsequently stopped and failed a roadside breath test.
The motorist was then arrested and taken to the local Garda station where a further breath analysis was carried out.
Meanwhile in Ballybofey a driver was arrested on suspicion of drink driving, prosecution is to follow.
