WA Police Union president George Tilbury says the proposal involves fitting immobilisers and GPS tracking devices in vehicles as they are manufactured.

"In certain circumstances where a vehicle needs to be stopped, a call will be able to be made to the manufacturer or another point to ask if that particular vehicle can be disengaged," Mr Tilbury told reporters on the sidelines of the union's annual conference in Perth on Monday.

"All manufacturers of high-end vehicles currently have access [to technology] to immobilise a vehicle remotely."

Mr Tilbury said there would be clear parameters for use of the technology, which could thwart a terrorist attack or end a prolonged pursuit.

Police Minister Michelle Roberts said her counterparts from around the nation backed the proposal at a recent meeting.

"We're keen to see it progressed," she said.

"All of us have seen the tragic results of crashes that have occurred where someone has absconded from police travelling at high speeds, going through red lights, travelling on the wrong side of the road.

"When you've got a vehicle doing that, it's a hazard to everyone."

Police Commissioner Chris Dawson said it was a worthy initiative and rejected suggestions there would be privacy concerns.

Queensland's police union wrote to the prime minister about the proposal around one month ago but has not yet received a response, Mr Tilbury said.

"There is full support within the Police Federation of Australia to lobby the federal government for these changes," he said.
