Jackson Mark Bailey, 19, was spotted by police driving a white Ford Falcon along Wilkins Street in Dubbo about 11.20pm on September 11 this year.

Police followed the vehicle after they noticed the ute travelling at speed around parts of Dubbo.

Despite police turning their siren and warning lights on, Bailey refused to stop and a pursuit began.

According to police, Bailey was spotted travelling at a speed of 150km/h in a 60km/h zone along Thompson Street, and was seen to "fish tail".

Bailey ended up on the Mitchell Highway and headed toward Narromine, when police said the vehicle was seen to cross over to the wrong side of the road, while reaching speeds as high as 170km/h in the signposted 110km/h zone.

As the pursuit continued, police in Dubbo went to the address the vehicle was registered to. While at the address, they established Bailey was on the phone to his mother, who had been making attempts to get him to pull over for police.

He ended up in Narromine when police terminated the pursuit because of safety concerns.

After Bailey returned to Dubbo, police met him at his home, when he told officers he didn't stop because he had been drinking alcohol.

A breath test recorded a reading of 0.027 - the legal limit for p-plate drivers is zero.

In Dubbo Local Court on Wednesday, Bailey pleaded guilty to a driving dangerously during a police pursuit and special range drink-driving.

Defence lawyer David Hemsworth said his client had been at a friend's house before the pursuit as he "had troubles with his brother" at home.

The court heard Bailey was being treated by a psychologist before the pursuit and panicked "losing his head" when he noticed police following him.

"He tells me that he's been diagnosed with an anxiety disorder and is currently taking what he describes as sleeping pills," Mr Hemsworth said.

However Magistrate Robert Prowse described Bailey's behaviour as "hideous".

"I spend my weekends either watching car racing or cage fighting just so I know what people like you are subjecting people to," Magistrate Prowse told Bailey.

"When you're doing 170km/h and your wheel blows, you're absolutely cactus.

"You should have been charged with intimidation for the agony you put your mother through but you haven't been for some reason."

Magistrate Prowse said he accepted a psychological report tendered, which showed Bailey's "absolutely extraordinary criminal action" was "probably the product" of his anxiety, and the only thing changing full time imprisonment to a sentence served in the community.

"My preference is to lock you up full time so that when I'm tootling about, I don't have to worry about you being in front of me, behind me or beside me," Magistrate Prowse told the court.

Bailey was convicted and sentenced to a 21-month term of imprisonment to be served in the form of a community based intensive corrections order.

He was also fined $1800, disqualified from driving for five years and banned from consuming alcohol for 21 months.
