A driver has tested positive for cocaine at one of the first drug-driving checkpoints set up by gardaí.

The motorist, who was currently disqualified from driving for 10 years, was stopped on the N4 between Dublin city and Leixlip.

Gardaí did not waste any time in rolling out the new drug-driving tests after a new Road Traffic Bill was passed in the Dáil and Seanad in December 2016.

The first checkpoints were rolled out at midnight on Wednesday this week, with gardaí tweeting about a checkpoint in Stillorgan on Saturday evening.

The new legislation makes it illegal for motorists to drive while under the influence of cannabis, cocaine or heroin.

It is also now an offence to drive while under the influence of the cannabis-containing drug Salvidex, used in the treatment of multiple sclerosis.

Minister for Justice Frances Fitzgerald told the Dáil in February that waiting until the Easter bank holiday weekend would “allow time for all stakeholders to prepare for introduction” and “provide a valuable opportunity to highlight the dangers of drug-driving over the bank holiday weekend”.

Gardaí tweeted on Saturday evening about what they called “Operation Surround,” saying: “N11 Stillorgan motorists are being tested for Drink and Drug Driving. All checks are for Intoxicant Testing.”
