Sniffer dogs have been deployed at some checkpoints across the country as gardai clamp down on road offences over the bank holiday weekend.
Gardai in Killarney conducted a checkpoint on the N22 on Saturday with the Roads Policing Unit and Garda Dog Unit.
MIT checkpoints checking drink and drug offences are also being ramped up across Ireland with four intoxicated drivers arrested at one stop in Louth on Friday.
