In Australia, which drives on the left, left turns on red are only permitted if a sign exists at the intersection. At such intersections, the sign generally reads "left turn on red permitted after stopping," meaning a vehicle can make a left turn only after coming to a complete stop first and giving way to approaching traffic and any crossing pedestrians or cyclists. Such signs are only in limited locations in the states of New South Wales, Queensland, South Australia (six locations as of 2016) as well as the Northern Territory and Australian Capital Territory and are banned in other states. In New South Wales, a number of tests to the intersection must be met before a turn on red will be permitted, including pedestrian volume, bus stop locations, geometry of the intersection, and the amount of lane changing at the intersection. There are conflicting views on the policy of left turns on red, with supporters pointing to lower vehicle emission and time savings, while opponents cite safety concerns.
