A Trinity College study has found that pedestrians are at a far greater risk of being killed if they are hit by a sports utility vehicle (SUV) than if they were hit by an ordinary car.
Researchers say the likelihood of a pedestrian fatality is almost doubled if the collision involves an SUV.
The study calls for all SUVs to be fitted with safety warnings.
However, the Society of the Irish Motor Industry says that would be an overreaction; the society disputes the figures.
Ireland saw an 8% rise in new registrations of SUVs last year.
