On a dual carriageway, which lane should you typically occupy if not overtaking?

On a dual carriageway, the left lane is typically the lane you should occupy if you are not overtaking. This is because the left lane is designated for normal driving and is intended for vehicles that are traveling at a steady speed. Using the left lane helps ensure that the right and middle lanes remain available for faster-moving traffic and those who are overtaking.

By staying in the left lane, you contribute to a smoother flow of traffic and reduce the likelihood of congestion in the other lanes. It also allows overtaking vehicles to maneuver safely in the right and middle lanes without having to weave through slower-moving traffic. In most driving regulations, it is considered courteous and safe to keep the left lane clear for those who need to pass, aligning with the principle of maintaining proper lane discipline on dual carriageways.
