A rule that in my experience, many drivers in Canberra are unaware of, or simply choose to ignore.
77 Giving way to buses.
(1) A driver driving on a length of road in a built-up area, in the left lane or left line of traffic, or in a bicycle lane on the far left side of the road, must give way to a bus in front of the driver if:
(a) the bus has stopped, or is moving slowly, at the far left side of the road, on a shoulder of the road, or in a bus stop bay; and
(b) the bus displays a give way to buses sign and the right direction indicator lights of the bus are operating; and
(c) the bus is about to enter or proceed in the lane or line of traffic in which the driver is driving.
In the ACT, a driver of a vehicle who fails to give way to a bus is liable to loose 3 demerit points.
