Intersections and lane use
We drive clockwise around roundabouts (turning circles) and give way to the right.
At T-intersections, vehicles on the top of the T have right-of-way over vehicles on the bottom of the T. The complete intersection rules are here.
If you want to turn right from a through road into a side road you must give way to drivers coming towards you who are passing through or turning left.
You are allowed to overtake on the left on multi-lane roads.
You are not allowed a free turn on a red light (unlike, for example, in the USA).
It is an offence to obstruct traffic. If you have a queue of vehicles following you because you are driving well below the speed limit, you must periodically pull over to let them past.
Clearways are areas where parking is restricted during certain hours. A dashed yellow line next to the kerb means no parking at all.
