In NSW bicycles can ride on the road and are considered a vehicle. As such they must follow all road rules like a motor vehicle, this includes coming to a complete stop at a stop sign and not using a mobile phone while riding.
Yet there are special rules that apply to bike riders. Bike riders:
Bike riders can also ride in the middle of the lane, they do not have to ride as far left as possible. The laws states "On a single lane road all vehicles must drive as close to the left as practicable," which applies to both cars and bikes. On a multi lane road, bike riders can occupy the middle of the lane.
Bike riders can ride in bus lanes and is often a way to avoid the heavy flow of traffic. However if a sign appears with the words “Bus-only lane” the lane must be vacated.
