A coroner has told an inquest in Clonmel that truck drivers must ensure they take appropriate rest periods on the road to avoid being a danger to other drivers.
Coroner Paul Morris was speaking at the inquest into the death of 26-year-old Nicola Kenny, who died instantly from multiple injuries when the car she was in was struck from behind by a lorry in September 2016.
Nicola Kenny, from Thurles, Co Tipperary, was a back-seat passenger in a car when it was struck by a lorry on the hard shoulder on the M8 near Cashel on 5 September 2016.
It happened just a day after she had given birth to her daughter Lily-Rose, and she was on her way to Temple Street Hospital with her aunt and mother.
They pulled into the hard shoulder to take a call from the hospital about the condition of her day-old baby girl when the collision occurred.
Nicola died of multiple injuries, consistent with road traffic accidents.
Her inquest in Clonmel heard how other drivers became concerned when they saw the lorry driving erratically and veering into the hard shoulder.
The driver Ciaran McBride, from Armagh, was subsequently given an 18-month suspended sentence for careless driving. Driver fatigue was a factor in the accident.
Coroner Morris referred to the Road Safety Authority's road signs which warn "Tiredness Kills". He said if ever there was a case which illustrated the truth of that warning - this is it.
He said commercial drivers should heed their tachograph systems and take appropriate rest periods so they are not a danger to other drivers.
