In Tasmania, what is a 'shared zone' and what is the key rule for drivers in one?

1. A zone where vehicles and cyclists share the road — cyclists have right of way
2. A zone near aged care homes, camp grounds, or similar areas where drivers must give way to all pedestrians in the zone
3. An area where two lanes merge — drivers must give way to the right
4. A shared parking zone where multiple vehicles can use the same space
