Bipartisan support for radar detector ban

The state Opposition has given tacit support to a ban on radar detectors on Western Australian roads.

The Police Minister, Michelle Roberts, says the sale and use of the devices will be banned under legislation to be introduced to Parliament in March.

Ms Roberts says existing anti-hoon laws will also be extended to allow police to impound the cars of people caught driving 45 kilometres or more above the speed limit.

Police have welcomed the moves.

The Opposition Leader, Matt Birney, is also supportive.

"Probably in this day and age it's pretty hard to argue that radar detectors serve any real purpose other than to assist people to break the law," he said.

"I don't have any particular problem with that but of course as with any proposals being put forward by the Government, I'd be very keen to see the detail of what is being proposed."
