The basic challenge for an unfamiliar driver will be that it is not left-hand turns which are problematic. Simply be in the left-hand lane, obey any traffic signals and a left-turn is easy. Review the local laws and know the street signs and speed limit. Practice in a safe beginner space. After you are familiar with the different visibility and turning radiuses required when making turns in a left driving, you can drive on a busy street.
As you become more accustomed to LHS driving, you’ll learn to look for the other car’s indicator. If it’s flashing a left hand turn, it won’t be in your path and you are good to go on. But always slow down and remember that even the locals get very conservative on multiple lane roundabouts.
It’s not uncommon to just ‘sit’ for up to a minute in this spot. A break in traffic will come, but you are also allowed to ’turn on the red’ if you are already in the intersection. That is, as oncoming traffic (and the flow-through behind you) stops to observe the new red light, you can hurry on through with your right turn before the intersecting traffic begins to move.
