Goulburn driver Adrian Ryan, 32, and Sydney driver Michael Gorman, 39, were killed in the early morning crash near Wilton on March 24, 2017.

Mr Ryan was a driver for Albion Park-based freight transporters, A. Fife & Co.

On June 12, Sydney Central Local Court fined company director Peter Fife. He had earlier been found guilty on charges arising from 24 offences related to the fiery double tragedy.

A. Fife & Co had been charged with another 24 offences relating to driver fatigue and breaches in the chain of responsibility for its duty of care.

Mr Ryan's B-double had collided with a car carrier driven by Mr Gorman about 5am on Picton Road, just north of the MacArthur Drive intersection near Wilton.

Mr Ryan was flung from his truck cabin, and died at the scene. Mr Gorman also died at the scene, and was found in his burnt-out cabin.

Crash investigators were on site all day, and Fire & Rescue NSW crews fought to contain the blaze as it spread to three of the cars under transport.

The Roads & Maritime Services investigation later led to the charges against the Albion Park freight company.

RMS compliance director Roger Weeks declined to comment on the ruling within the court's appeal period, but said the RMS would "continue to actively investigate and pursue chain of responsibility laws across the heavy vehicle industry to improve safety for all road users".

Mr Gorman's brother, Mark, said it was a relief to end the legal process after more than two years, but that "the dollar figure for the fine does not matter because it is never going to bring our brother [Michael] back".

The Gorman family hoped the verdict and penalties served as a warning to other truck companies to comply with fatigue regulations.
