The Department of Consumer Protection in Western Australia is investigating the merit of a proposal to ban the display of discounted petrol signs at service stations.
The Department is inviting public comment on the appropriateness of such signs, ahead of a meeting of state and federal ministers next month to discuss new national standards.
Consumer Protection says customers complain about the signs being misleading and confusing, and often don't realise they need a shopper docket to qualify for the cheaper petrol.
One proposal for a national standard is to ban discounted prices from being displayed.
Discounted offers could be displayed but not the discounted price.
