Four women were fatally injured in separate road incidents in counties Wexford, Clare, Meath and Tyrone on Saturday.
Among the victims was Theresa Morgan (63), a mother of three and grandmother, who was hit by a car on the R135 Dublin Road in Ashbourne, Co Meath.
She was described in tributes as a “fabulous woman with a big heart”.
Local Fianna Fáil councillor Conor Tormey, who is a family friend and former neighbour of Ms Morgan, said the local community was in “shock” following her death.

The incident occurred at about 7.10pm on Saturday and Ms Morgan was pronounced dead at the scene.
The male driver and passenger travelling in the car, aged in their 20s, were taken to Connolly Hospital Blanchardstown to be treated for what were said to be non-life-threatening injuries.
In Co Wexford, another pedestrian was killed in a road incident. The woman aged her 20s died after being hit by a car on the R702 road at Curraghgraigue, northwest of Enniscorthy in Co Wexford, at about 3pm on Saturday.
Gardaí and emergency services were called to the scene and the seriously injured woman was taken to Wexford General Hospital, where she later died.
A man (20s) who was driving the car received medical assessment at the scene, An Garda Síochána said.
In Co Clare, a woman died after being hit by a tractor while cycling. The incident happened on the L3180 road at Toonagh, Tulla, at about 12.45pm on Saturday.
“The cyclist, a woman aged her 70s, was pronounced deceased at the scene,” An Garda Síochána said.
The woman’s body was taken from the scene to the mortuary at University Hospital Limerick, where a postmortem will take place in due course, the Garda added.
Gardaí have appealed to anyone with information about the three incidents, or with camera footage that could assist the investigations, to come forward.
The three deaths bring the number of fatalities on the State’s roads so far this year to 65, including 18 pedestrians and five pedal cyclists.
