An inquest in Mayo has heard calls for anti-roll bars to be fitted as standard on quad bikes.
The call by Mayo Coroner Patrick O'Connor came at the conclusion of an inquest into the death of a 67-year-old farmer.
Tony O'Malley died when a quad he was driving overturned and trapped him beneath last September.
At Castlebar Coroner's Court today, consultant pathologist Dr Fadel Bennani said the cause of death was asphyxia due to entrapment.
The inquest heard there are no requirements for anti-roll bars to be fitted on such machines at present.
Mr O'Connor said the increased use of the vehicles on farms, as well as in industrial and recreational settings, meant stricter regulations were needed.
The jury returned a verdict of accidental death and said that research should be carried out on the safety of all quad vehicles.
Echoing the jury's recommendation, the coroner said the suggestion of a panic button on quads, to raise the alarm in case of emergency, was also worthwhile.
