FARM safety groups have backed calls by the Victorian Coroner for quad bike manufacturers to cease marketing them as all-terrain vehicles.

In the wake of an inquest into several quad-bike deaths, Coroner John Olle told quad bike manufacturers this month to never again market or describe the four-wheeled motorbikes as all-terrain vehicles.

Mr Olle said to describe a quad bike as an all-terrain vehicle was a "serious overstatement of its capabilities".

Farmsafe Victoria manager John Curtis said he agreed with the Coroner's comments.

"They are not all-terrain vehicles and so should not be marketed in such a way," Mr Curtis said.

"People need to understand the limitations of quad bikes.

"The recommendations of the Coroner need to be implemented straight away, otherwise deaths and injuries will continue to occur."

Quad bike manufacturers met on Monday to consider the Coroner's findings.

A spokesman for the Federal Chamber of Automotive Industries, who represents the manufacturers, declined to comment until after a second meeting next week.

Mr Curtis said the Coroner's call for a certified training course for quad bike riders was a positive one.

"A certified training course is a positive step forward, with lots of people operating quad bikes with little experience," he said.

Farmsafe Australia executive officer John Temperley said quad bike deaths were starting to exceed tractor roll-over deaths in Australia.

"There are, on average, 12 quad fatalities per year," Mr Temperley said.

"(Quad bikes) are designed for personal transport and are unsuitable for many jobs on farms."

Tony Mahoney, a 57-year-old farmer from Alvie, north of Colac, said he backed the Coroner's findings.

Earlier this year, Mr Mahoney narrowly escaped death after his quad bike flipped while he was spraying weeds.

He was trapped under the bike for eight hours and was left with a dislocated hip and broken pelvic bone, which kept him wheelchair-bound for three months.

Mr Mahoney said he hoped the inquest would lead to an effective training program for quad bike users.

"It is essential. I back it 100 per cent," he said. "We need an education program that confronts us with the statistics."

Mr Mahoney said when the accident occurred he was "about to go back home. I closed the gate and zipped up the hill, forgetting that I had 50 litres of weed spray in the tank on the back of my bike."

Mr Mahoney said pushing quad bikes beyond their limit was a habit all operators must break.

He said it only took a "momentary lapse of concentration" to prove that the older you were, "the more easily distracted you become and the slower your reaction times are".

"People are too preoccupied about how many lambs they are getting this year, what the rain will be like," he said.

"This sort of accident puts everything into perspective. The costs to society of accidents like this are huge. It's a wake-up call for us all," he said.

On Wednesday, Mr Mahoney got back on his bike for the first time since the accident.
