Gardai say they're deeply saddened by the horrific death toll in Irish roads over the past week - a week in which 10 people died in road collisions - and have sent condolences to those affected by the tragic events.
In a statement, Gardai say their activities across the country will continue to focus on the offences that contribute most significantly to traffic collisions - in particular drink-driving and speeding.
In the first month of 2019 to date, 634 drivers have been arrested nationally for driving under the influence of drink or drugs, while over 9,300 people have been detected speeding.
In Mayo, one motorist was caught driving at 161 km an hour in an 80 km/h zone on the R335 at Glaspatrick, Murrisk.
The Road Safety Authority is also appealing to motorists to slow down, drive at the right speed for the weather conditions and watch out for vulnerable road users -particularly among warnings of icy roads and sleet and snow showers this week.
