Clodagh Shannon, 41, from Kerry Pike on the outskirts of Cork City, died after a two-car collision on the R588 road at Coppeen East, Enniskeane, on the Coppeen to Crookstown Road, at around 9am.
Several motorists who came upon the accident tried desperately to help her.
Gardaí and emergency services were also on the scene quickly but despite their efforts, Ms Shannon was pronounced dead at the scene.
It is understood that Ms Shannon was on her way to work in West Cork at the time of the accident which occurred shortly after she had rounded a right-hand bend in the road.
Her body was removed to Cork University Hospital where a postmortem will be carried out shortly.
The driver of the second car, a man in his late 50s, was taken to Bantry Hospital where he was treated for minor injuries.
There were reports of black ice on roads in the area at the time, which made driving conditions treacherous, but gardaí said it is too early to say if the cold weather or icy road conditions were a factor at the time of the fatal accident.
The road was closed for several hours to facilitate an examination by Garda forensic collision investigators.
Their findings will form part of the file which gardaí will prepare for the coroner’s court.
Gardaí in Bandon are investigating the accident and have appealed to witnesses to contact them on 023-8852200.
Ms Shannon’s death has brought to 12 the total number of people who have died on the roads since the start of the year — two more than for the same period last year.
The fatalities before yesterday’s accident included one pedestrian, one cyclist, three drivers and six passengers.
Figures from the Road Safety Authority published on December 31 last showed an increase in road deaths for the second consecutive year.
A total of 196 people lost their lives on the roads in 2014, compared to 190 in 2013 — a 3% rise.
However, last year’s figures represented a 21% increase when compared to the 2012 road death figures — the safest year on Irish roads when 162 people were killed in road traffic accidents.
Meanwhile, a 75-year-old man was last night fighting for his life in hospital after a single vehicle collision on the Rochestown Road in Cork City.
The accident happened at around 6.30pm. It is understood the man was travellling from Crosshaven when he apparently lost control, veered across the road and hit a tree.
