Two-thirds of women passengers killed in car crashes are travelling in vehicles driven by men.
1,444 women have been killed or seriously injured in cars driven by men in the ten-year period to 2006.
Of the 345 women passengers who died in that period, two-thirds of them were in cars driven by men.
The Road Safety Authority has launched a new campaign called 'He Drives, She Dies' aimed at young women, designed to empower them to say no to getting into a car with a man who drives dangerously.
In the recent research, young drivers were shown to be particularly dangerous.
Seven out of 10 female passengers aged between 17 and 24 were killed in cars driven by men in the same age group.
Research carried out in border counties shows eight out of 10 passengers have felt unsafe in a car.
Speeding was the most common factor causing fear, with many passengers saying they feared the driver would accelerate if they commented on the vehicle's speed.
More than half interviewed said they would accept a lift from someone who had been drinking.
