One of his victims feared for her life and said her relationships had suffered as a result He will be eligible for parole after serving two years and five months' jail.

Elten Gevergizyan terrorised motorists in Melbourne's north by deliberately driving into their cars and attacking them with weapons in a three-day rampage in May last year.

Gevergizyan pleaded guilty to 15 offences including reckless conduct endangering serious injury, intentionally damaging property and intentionally destroying property.

He will have to serve two years and five months before becoming eligible for parole.

At his sentencing on Thursday, one of his victims, Julie Dougherty, said the hearing brought back the terror she felt when he forced the car she was a passenger in against a concrete barrier on Melbourne's Tullamarine Freeway.

"I thought I was going to die, twice," Ms Dougherty said.

Gevergizyan was driving a five-tonne truck and towing a trailer carrying a three-tonne excavator at the time.

He drove up next to the car Ms Dougherty was in, driven by another woman, and deliberately hit it, damaging its rims, side mirror and door panels and forcing it into the safety barriers before ramming it again.

When the women followed Gevergizyan in their car and took a photo of his number plate, he waved a stick out the window and made a cut-throat gesture at them before pulling over.

When they got out of the car to get Gevergizyan's details, he ran towards her, swinging a hammer at her.

Ms Dougherty then attempted to flee, but Gevergizyan gave chase and pushed her over, standing above her yelling, "Get back in the car or I'll take your rego and find out where you live" and, "You're not calling the police".

Ms Dougherty said she was forced to cower in a ditch as he stood above her yelling, hammer raised in his hand.

When they returned to their car, Gevergizyan used the hammer to smash its side mirror and passenger-side window. Then, as they tried to drive away, he smashed a rear window, dropping the hammer inside the car.

Ms Dougherty said she now felt confident in the justice system.

"I've got a little bit more hope in the legal system after today … I really believe the judge we got today cared about the people involved," she said.

"For me it's closure."

Ms Dougherty said her lifestyle had been severely affected since the attack, especially relationships with her friends.

"I'd thought I got over it until I heard the stories … I'll probably feel sick for a couple of days," she said.

"There's really sadness about trauma.

"I lost a lot of friends through this, because people that don't go through it think you're just doing it for attention, they think you're talking rubbish."

Victims 'suffered considerably'

During his sentencing hearing, the Victorian County Court heard Gevergizyan, from Mickleham in Melbourne's north, had a history of driving offences, assault and drug use.

Judge Susan Pullen described his behaviour as "appalling" and "disturbing".

The victims told the court they were terrorised and their lives had been severely affected by the attacks.

Gevergizyan initially pleaded not guilty and blamed the other motorists for the three attacks, which occurred over three consecutive days.

Judge Pullen said he had anger management issues and lacked remorse.

"You had time to consider your actions, yet you repeated similar incidents two and three," she said.

"The victims of your offences have suffered considerably."

Gevergizyan described one of his victims as having "a devilish smile like a witch" and said he did not think she was scared of the hammer he used on one of the cars.

He told police he just wanted to get home from his job.

An agreed summary of facts, released by the court at an earlier hearing, said the first attack happened when Gevergizyan was driving his truck and blasted his horn at a woman as she drove north on the Tullamarine Freeway near Melbourne Airport on May 25.

He overtook the woman's car on solid double lines and struck her vehicle, causing damage to the driver-side mirror.

When the woman drove after Gevergizyan to get his details he stopped, got out of his truck and ran towards the woman's car, punching it before she drove away and reported the incident to police.

The attack on Ms Dougherty happened the following day.

On the third day of his rampage, Gevergizyan was driving a van when he pursued and tailgated a man and his wife.

The couple had sounded their horn at him when he suddenly pulled out in front of their car on the Hume Highway, forcing them to brake suddenly to avoid a crash.

After the couple drove ahead, Gevergizyan pulled alongside, signalling them to pull over before intentionally side-swiping their vehicle and accelerating away.

The pair called triple-0 and drove after Gevergizyan, stopping behind him when he pulled off the highway.

Gevergizyan took a baseball bat from his van and started hitting the couple's car with it, smashing the driver-side mirror and windows before driving off.
