What should the left-hand lane of a motorway be used for?
Normal driving
Overtaking traffic in the middle lane
Vehicles doing the minimum speed limit
Explanation: Drivers on dual carriageways (which may or may not be motorways) are legally required to use the left-most lane unless overtaking other vehicles on the road, unless signs or road markings indicate that the left-most lane(s) is only for traffic leaving at the next junction.
