Which vehicles should use the left-hand lane on a three-lane motorway?

Explanation: On a motorway, all traffic should use the left-hand lane unless they're overtaking. Use the centre or right-hand lanes if you need to overtake. Make sure that you move back to the left-hand lane when you've finished overtaking. Don't stay in the middle or right-hand lane if the left-hand lane is free.
