Which vehicles are allowed to use the left-land of a three-lane motorway?

Explanation: On a motorway, all traffic should use the left-hand lane unless overtaking. When overtaking a number of slower vehicles, move back to the left-hand lane when you're safely past. Check your mirrors frequently and don't stay in the middle or right-hand lane if the left-hand lane is free.
