Regulatory signs say what you must or must not do, and ignoring them is an offence. Lane signs tell you which vehicles may use a lane and when.
- Special purpose lanes are set aside by signs and/or road markings. Stay out of them during the times shown, or at all times if no times are shown.
- You may use one for up to 100 m (only 50 m in a bicycle or tram lane) when you need to enter or leave the road or avoid an obstruction.
- Where a Keep Left Unless Overtaking sign is shown (or on multi-lane roads over 80 km/h), stay out of the right lane unless you are overtaking, turning right, making a U-turn, avoiding an obstruction or in congested traffic.
