Over 750 motorists were caught speeding during National Slow Down Day.
Gardai were out in force along with GoSafe between 7am yesterday and 7am this morning.
Quite a number of notable detections were made in Donegal including a driver speeding close to a primary school near Burnfoot.
A motorist was arrested last night by the Letterkenny Roads Policing Unit on suspicion of drug driving after testing positive for cocaine. They were initially stopped for a speeding offence.
Meanwhile, Gardai from Carndonagh seized a car after they detected it had no tax, insurance or NCT and had two bald tyres. It subsequently emerged that the learner driver behind the wheel had no L plates on display.
