Corey Jacob Blazevicious, 19, was sentenced at the County Court of Victoria on Thursday for his drug-fuelled crime spree across Ballarat's suburbs in May last year.

"Generally, your offending in relation to both indictments demonstrates that you were, together with others, effectively on a criminal rampage over a two-week period resulting in serious criminal conduct," Judge Trevor Wraight told Blazevicious.

The crime-spree started on May 12, last year - about a month after the then-18-year-old was released from custody for previous offending - when his fingerprints were found inside a Holden Captiva vehicle taken from Lake Gardens.

On May 19, Blazevicious was seen driving a stolen Toyota Kluga taken a day earlier from the victim's Alfredton driveway and with a co-accused, stole two registration plates from different cars.

The most serious offending occurred about 1am on May 22 when Blazevicious and co-accused Brody Harris allegedly stole a white Ford Ranger ute from a Canadian driveway.

Harris allegedly picked up two other men, Jarrod Cakebread and Bryce Stephens, and they were driving on Howitt Street in Wendouree about 2.40am.

They saw a man drive past who Harris said owed him money and Harris allegedly sped up to the victim, rammed his car in the rear and continued to pursue him along Doveton Street.

The victim tried to drive to Ballarat Police Station while Harris allegedly continued to ram his car a number of times, before blocking his escape when he was stopped by railway crossing boom gates.

Blazevicious was armed with a knife and stabbed the victim's airbag to gain access to his car.

Co-accused Jarrod Cakebread allegedly demanded drugs and money while holding a knife to a second female victim who was in the car.

Blazevicious climbed into the car and stabbed the male victim once to the chest and once to the back, before running away.

Judge Wraight said this offending reflected very serious and frightening conduct.

"In my view the armed robbery can only be viewed as a serious example of armed robbery in company and your stabbing of the victim represented a perpetuous, cowardly and unnecessary act on your part," Judge Wraight said.

On the same evening of the stabbing, Blazevicious was seen driving another stolen car into a service station and two days later, a Suzuki Swift stolen from a Mount Helen car park was later linked to him.

On May 25 police were informed a Holden Commodore stolen from Alfredton was located in a bowls club car park in Ballarat East.

Police entered the car park in an unmarked car with emergency lights activated, saw the stolen Commodore and a stolen Ford Kluga on fire.

Blazevicious, Cakebread and co-accused Wade Turner were seen running to the Commodore.

Blazevicious was charged with being complicit in deliberately setting fire to the car.

Blazevicious got in the driver's seat and sped towards the police car.

The police officer swerved to take evasive action and Blazevicious continued driving at the vehicle, swerving late and narrowly avoiding hitting it.

The court heard Blazevicious sped at a second police vehicle, again narrowly avoiding hitting it.

Blazevicious was captured on a traffic camera driving at 199km/h in a 100km/h zone on the Princes Highway later that night.

Police saw him driving erratically in Werribee with no headlights and sparks coming from the rear wheel.

The trio dumped the car, which was missing a wheel and were arrested by police in Point Cook.

Blazevicious was on parole at the time of the offending and has been in a youth Justice Centre for the past 12 months serving another sentence.

The court was told the teenager was influenced by older, drug-addicted males at the time of the offending.

Blazevicious was sentenced to five years and seven months' imprisonment on Thursday, with a non-parole period of two years and 10 months.

He was disqualified from driving for two year. If he did not plead guilty Blazevicious would have been sentenced to seven years' imprisonment with a non-parole period of four years, according to the judge.

Blazevicious pleaded guilty to nine charges of theft, and one count each of armed robbery, arson, recklessly causing serious injury, exposing an emergency worker to risk by driving and recklessly endangering serious injury by driving.
