Re: Vehicle in Yellow Box - Legal?
the yellow box is for vehicles from smaller lanes to join the main road. That's why the traffic rules say no vehicles in main stream of traffic are supposed to stop in the yellow box. To allow space for vehicles from small lanes for joining in, whenever the traffic is crawling or there is a jam.
This however does not apply when the main stream of traffic is moving at normal speed, then the vehicles from the smaller have to wait for an opportunity to join instead. Same goes for bus stop bays, when main stream traffic stalls/crawls, the bus is supposedly allowed to cut in to join main stream of traffic.
