But Thomas Robins, 23, still faces charges of negligent driving causing death and drink driving in the over the fatal accident.

Kyall Green, 22, was fatally injured when the car he was travelling in rolled at the intersection of Cannan Crescent and Constance Stone Street, Macgregor, on January 20 last year.

He died the following afternoon.

An ACT Supreme Court jury deliberated for less than three hours before finding Robins, the driver of the ute, not guilty of culpable driving causing death.

Robins was backed throughout the two day trial by a large contingent of supporters, including family of Mr Green.

The group cheered, clapped, and Robins broke down in tears as the jury delivered the not guilty verdict in court on Tuesday morning.

During the trial, jurors heard Robins and Mr Green had been part of a group of four men driving from a party to the accused man’s Macgregor home about 12.45am.

Robins drove the Mitsubishi Triton utility, with Mr Green in the passenger seat, and two men in the tray.

Mr Green had hanging out of the ute's window to take photos of the men riding in the tray when the car rolled.

He was crushed and died of his injuries the following afternoon.

The Crown alleged the accident was caused by a combination of Robins' intoxication and being distracted by his passengers.

But defence barrister James Lawton argued Robins' actions did not match the definition for culpable driving, which required jurors to find he, to a gross degree, failed to take the standard of care that a reasonable person would have observed in the same circumstances.

Justice John Burns acquitted Robins on Tuesday.

Robins has pleaded not guilty to the remaining charges in the ACT Magistrates Court.

They will reappear later this year.
