The trial at Naas Circuit Court of a woman accused of dangerous driving causing the deaths of four of her friends has heard there was no air in one of her tyres.
Aisling Midleton, Niamh Doyle, Gemma Nolan and Chermain Carroll died instantly when the car they were in crashed into a van in January 2015.
It happened on what was described as a "relatively new and reasonably straight" stretch of the N78 in Athy, Co. Kildare.
The driver of the car, Dayna Kearney from Crossneen, Co. Carlow, has also pleaded NOT guilty to knowingly driving a defective vehicle.
It is the prosecution’s case that the under inflation of tyres caused the car to veer and swerve into the oncoming van.
