Two men have admitted their involvement in a vicious road-rage incident that left a Gold Coast tradie fighting for his life.
Brock Prime, then aged 29, suffered a severe head injury that left his brain exposed when he was assaulted by a group of men on the side of the M1 motorway near Yatala on February 24, 2018.
Jonathan Christopher Lawerence, 29, pleaded guilty to one count of grievous bodily harm in the Brisbane District Court on Tuesday, while Jordan Jonathan Baklas, 30, pleaded guilty to one count of assault occasioning bodily harm.
Charges against 31-year-old Ryan David Hallifax were dropped.
Police said at the time up to 13 people may have been in a white van involved in the incident.
Officers reported the van and Mr Prime's black Subaru Forester came close to colliding on the M1 around Coomera sparking a "cat and mouse game" during which the vehicles ducked and weaved through traffic in wet conditions before pulling over.
Mr Prime's family was told by doctors he had suffered a fracture to his skull in the attack, according to social media posts at the time.
More than two weeks after the bashing his family said he had woken from a medically induced coma, but had a long road to recovery ahead.
Lawerence and Baklas are due to be sentenced in the same court on May 14.
