24,255 people have been killed on Irish roads since records began.
Today they're being remembered as part of 'World Day of Remembrance for Road Traffic Victims'.
It's a day when commemorations take place globally to remember those injured or killed in road traffic collisions.
Brian Farrell from the Irish Road Safety Authority noted that the day also provides a chance to review road safety.
He explained: "It's an opportunity for us all to remember those who have been killed in road crashes; those who have been seriously injured; and of course the families that have been left behind.
"Critically, we want to use the day as a catalyst for everyone out there to reflect on their own road user behaviour, and look at making small changes to the way we use the roads."
In a statement, Transport Minister Shane Ross observed: "For the majority of Irish people, [today] will pass unnoticed. They will not stop to mourn and miss loved ones, nor wonder 'if only' or 'what if'.
"Yet up and down the country there are hundreds, thousands of people doing just that. Families, friends, colleagues and communities, all are mourning the loss of a loved one – an unnecessary loss that should never have happened."
He added: "This winter – don’t drink and drive. Wear your seat belt. Look out for cyclists and pedestrians. Don’t use a phone while driving. Heed the speed limit. Keep yourself and others alive this winter.”
