In the UK, the term "outside lane" refers to the higher-speed "overtaking lane" ("passing lane" in the US) closest to the centre of the road, while "inside lane" refers to the lane closer to the edge of the road. In the US, "outside lane" is used only in the context of a turn, in which case it depends in which direction the road is turning (i.e., if the road bends right, the left lane is the "outside lane", but if the road bends left, it is the right lane). Both also refer to "slow" and "fast" lanes (even though all actual traffic speeds may be at or around the legal speed limit).
