Dr Tony Casey made his remarks at an inquest in Limerick which was told that a teenage woman died after a fall from a dirt motorbike driven by a friend on a Co Limerick farm.
The jury returned a verdict of accidental death on Lisa Roche, 18, from Tallyho, Rathkeale.
She never regained consciousness after falling from a dirt bike at Foley’s Farm, Askeaton, on April 16. She died from her injuries the following day.
Stephen Foley, 24, of Milltown, Askeaton, said he and a number of cousins and Ms Roche brought three dirt bikes and a quad bike to the River Field at about 7pm.
Ms Roche asked him for a drive on his bike and she sat on the bike in front of him.
Her feet were placed straight out because his feet were on the bike’s foot pegs. They were driving around two fields for about 10 minutes and the next thing he remembered was waking up and seeing Lisa on the ground.
Neither of them was wearing a helmet.
Sarah Foley said she was in the field with her cousins and Ms Roche. She was talking with Ms Roche who asked Stephen if she could go for a drive on his bike with him. They drove off around the field and went on into another field.
After they returned to the river field she saw Ms Roche and Stephen in the air. She could not remember seeing them hitting the ground. She tried to wake Ms Roche up. Ms Roche was breathing but never regained consciousness. Medical evidence was given that she died of head injuries.
Recording a verdict of accident death, coroner Dr Tony Casey said the importance of wearing helmets while travelling on motorbikes had to be emphasised.
Coroner Casey, Inspector Gerry McNamara and jury foreman, Patrick O’Byrne extended their sympathy to the bereaved family.
