Garda Commissioner Drew Harris has urged caution on Irish roads ahead of the Bank Holiday weekend, as the number of road fatalities and serious injuries from collisions surpasses last year’s total in the year to date.
As of last Thursday, there were 89 deaths on Irish roads, an increase of 28 deaths compared to this time last year, and an increase of 13 deaths compared to this time in 2019.
Mr Harris told reporters in Athlone on Monday: “Obviously, this is of great concern, not just the fatalities but the serious injuries as well.
“And we would say to people, the message is always simple: slow down, don’t drink and drive, wear your seatbelt, don’t use your phone.
“Those are the simple messages which will keep people alive and save people from serious injury. We appeal to people to follow that simple advice, please.” Minister for Justice Helen McEntee reiterated Mr Harris’ comments, asking people not to drink and drive, not to use their phones while driving, to wear their seatbelts and “above all, to reduce your speed”.
“It’s an absolute tragedy when anybody loses their lives, I just want to offer my condolences in particular to the families who have tragically lost those [who died] on our roads only in the last few days.”
