You are driving on a two-lane dual carriageway with light traffic. You are travelling at the speed limit in the right-hand lane after overtaking a slower vehicle. To drive in a way that is safer and more environmentally friendly, what should you do next?

Explanation

The Highway Code Rule 137 states that on a two-lane dual carriageway you should stay in the left-hand lane and use the right-hand lane only for overtaking or turning right. After overtaking, you should move back to the left-hand lane when it is safe. Keeping to the correct lane helps traffic flow smoothly, reduces unnecessary braking and acceleration, and can lower fuel consumption and emissions, supporting more environmentally responsible driving.
