Naas Roads Policing Unit said it operated a super Mandatory Intoxicant Tests checkpoint on the R448 between Naas and Newbridge.
Gardai said a total of 172 drivers were tested for alcohol and drugs - and all passed.
Some five other offences were detected and Fixed Charge Penalty Notices were issued.
Under new powers included in the Road Traffic Bill 2016, Gardaí can ask drivers to undergo a preliminary drug test for cannabis, cocaine, a range of opiates (including heroin and morphine) and a range of benzodiazepines (including diazepam and flurazepam).
Drivers abusing drugs and driving while impaired will face a minimum disqualification of four years for their first offence and six years for their second and subsequent offence.
