Luke Newsome died on January 6 after he fell off the back of his mate Alister Spong's 1942 flat bed truck at the annual car festival.

Mr Spong was charged with culpable driving but cleared of all charges at trial.

The trial heard Mr Spong was lapping the Summernats cruise route on January 5, 2017, with five friends on the tray, when he attempted to spin his 1942 Ford Jailbar truck's back wheels, a move he called a "chirpie" and one he said he had done many times before.

But Mr Spong had failed to take into account the weight of his five passengers. Instead of losing traction the wheels bit into the road and the truck lurched forward, sending two friends off the back.

A coroner's report tabled in the ACT Legislative Assembly on Thursday said a hearing into the matter was not necessary.

Coroner Robert Cook said while the matter did raise matters of public safety, he believed Summernats organisers had already addressed them.

That included the festival banning riding in the back of utes and requiring people to wear seatbelts.

The coroner said the organiser also restated that burnouts were banned at the event, with the exception of certain events.

The Summernats festival has not been without incident since it kicked off in 1987.

In 2006, four people were injured when a ute performing in a stunt show crashed through the perimeter fence and in 2000, a security guard was hit on the left leg by a car.

Mr Newsome's death was the first in the festival's history.
