The Road Safety Authority is urging motorists to be extra careful while driving this evening.
Busier than usual traffic can be expected, as people make their way home following the long weekend.
It comes after five people lost their lives on Ireland's roads over the St Patrick’s weekend.
In County Louth, two men died in a single-vehicle collision on the R173 just outside Carlingford on the Omeath road last night.
A 28-year-old man was also killed in a crash in Toome, Co. Antrim, yesterday evening. He has since been named by the PSNI as local man Diarmuid McFall.
A motorcyclist in his 40s died in a single-vehicle crash on Whitestown Way, Tallaght in Dublin at approximately 7am this morning.
Yesterday, a man in his sixties was killed and 11 others were injured in a five-car crash on the M6 at Kilbeggan in County Westmeath.
It means 39 people have now been killed on the roads in 2019.
The Road Safety Authority are again urging motorists never to drive impaired, to slow down and to take a break if feeling tired.
