On a motorway, what is the left-hand lane used for?

Explanation: The left-hand lane is intended for normal driving, and you should aim to use the left lane whenever possible. Lanes to the right should be used only for overtaking, or as normal driving lanes when indicated by signals. You may find other drivers become frustrated if you drive in the middle or right-hand lanes while the left lane is empty.
