The owners of two electronic billboards have lost their bid for ministerial approval after an independent committee advised they posed "an unacceptable risk to the safety of drivers".
The two billboards — above the entrance to the Northbridge Tunnel and on top of a building in West Perth — have been switched off since 2022 after Main Roads exercised its power to order the switch off, deeming the signs with rotating messages "hazardous to traffic safety".
