Minh Thien Ho was sentenced to 12 months' jail, with a 9-month non-parole period, in Wollongong Local Court in October after pleading guilty to a charges of negligent driving and driving a vehicle while under the influence of drugs.

At the time, Magistrate Michael Stoddart said Ho was lucky he didn't kill himself or anyone else when his 25-tonne freight truck lost its brakes and collided with a power pole, parked car, and several fences while descending Bulli Pass on March 25.

The truck then hit the median concrete barrier with such force it caused the vehicle to become airborne, before crashing into other cars on the opposite side of the road and landing on its side.

The 30-year-old was able to free himself from the wreckage before the truck bust into flames.

A set of agreed facts tendered to Wollongong Local Court said a witness driving in the opposite direction had to slam on their brakes and reverse quickly to avoid a collision with the out-of-control truck.

A blood sample taken at hospital showed Ho was under the influence of methylamphetamine and had enough in his body so that his "driving would have been impaired".

Ho represented himself in the Local Court, saying he would take "full responsibility with whatever punishment you give me".

However, not content with his sentence, Ho subsequently lodged an appeal against his imprisonment.

In Wollongong District Court on Friday, Legal Aid lawyer Tim McKenzie said Ho had been in jail for 50 days and had had time to reflect on his crime.

He said Ho acknowledged he had a problem with drugs and wanted to get help.

"I'm asking the court to consider an intensive corrections order as an alternative to full-time custody," he said.

Judge Geoffrey Graham refused to change Ho's sentence to a community-based intensive corrections order but agreed to shave two months off his non-parole period to allow him more time on supervised release.
