Doctors have said a baby girl is lucky to be alive after she was delivered on the side of a road in Kilkenny.
The girl's mother went into labour as she was driving to the way to hospital.
The incident happened last night in what were described as very foggy and cold conditions, with the temperatures below freezing.
The woman, a mother-of-three, was driving from Carlow to St Luke's Hospital in Kilkenny after 7.30pm.
She went into labour and crashed into a roundabout on the outskirts of the city.
A number of passers-by stopped at the scene, including Eamonn and Mae Doyle from Kilkenny city.
Mr Doyle, a retired Garda, told RTÉ News that another young man who had come upon the scene told him the woman was going to have a baby.
Ms Doyle said she made her way over to the car. The driver's door was open and the woman was lying back across the passenger seat.
She told Mrs Doyle: "Get ready to catch my baby."
Ms Doyle put out her hands and said the crying baby popped into her arms.
She said she told the woman the baby was fine, that it was a girl and that everything would be okay.
They managed to find a blanket and wrapped the baby as best they could.
The umbilical cord was still attached as they waited for an ambulance.
Mr Doyle had phoned an ambulance, which they say came nearly 20 minutes after the initial call.
The ambulance crew took the woman and the baby to hospital.
The girl weighed 7lb (3.17kg), but has not yet been named.
She suffered mild hypothermia, but is safe and well in St Luke's.
Her mother is said to be very grateful for those that helped deliver her little girl.
