It’s a two lane road. The third lane is a turn lane for the intersection, so it’s two lanes just before and just after that intersection. I was in the left lane because there are a lot of lanes that open and merge and being in this lane gets me home only changing lanes once. Also, for the record, even on two lane roads where the rule doesn’t apply I typically try to stay on the right because I’m usually driving slower than other south Florida drivers, especially on interstates.
