A Mount Barker man has been jailed for a series of crimes against his wife that ended with him deliberately running her vehicle off the road in an attack that was captured by the dash cam of another car.

Mark Burt, 48, chased wife Sandy Wolfe, who had a restraining order against him, through the streets of Albany in June last year.

A motorist who saw the drama unfolding followed Burt and recorded what was happening on the dash cam of their car.

The footage shows Burt forcing his wife's small car off the road, with the car rolling twice before coming to rest on its roof.

Ms Wolfe escaped with only minor injures.

She said the incident shocked her so much, she decided to tell police the history of violence she had endured at the hands of her husband, to whom she had been married for 28 years.

"I never dreamed that he would go that far as what he did. This was a wake-up call for me to get help," she said after his sentencing.

The District Court in Albany was told the violence included Burt tying a rope around her neck, attaching it to a ute and forcing her to run behind it at their farm.

Judge Michael Bowden described the incident as "degrading, humiliating and a deliberate attempt to harm her".

He also said Burt, in running Ms Wolfe off the road, had "pursued her in a manner that presented a danger to her and others".

Burt pleaded guilty to more than 20 charges, including 17 breaches of a violence restraining order that was taken out by his wife.

He also admitted trying to corrupt witnesses, with the court told that while he was on remand in jail, he repeatedly telephoned his sons to try to get his wife to lift the restraining order and to drop her claims of assault.

Burt was sentenced to five years jail.

He will have to serve three years before he is eligible for parole and, with time already served, could be released in 2017.

Supertintendent Dom Woods from Great Southern Police said the case reinforced the message that women should seek help when relationships turn violent.

"Please come forward, we are here to support victims of crime. As far as the WA Police force is concerned, it's the number one priority for us," he said.

Ms Wolfe echoed the comments.

"If only everyone had the facilities available to them, or realised that they are there [and] they just have to reach out, maybe this wouldn't be such a factor for women losing their lives nowadays," she said.
