What is a three-lane motorway?

Typically, a three-lane motorway is a highway divided into three lanes: Lane one, the left lane, is designated for regular driving. Lane two, the middle lane, and lane three, the right lane, are for passing. Maintain lane one until there is a buildup of slow-moving cars in that lane, in which case you can shift to one of the other lanes.
