Outside a built-up area you have completed an overtake and can safely return to the right lane. You will not overtake again and no other circumstance warrants remaining on the left. Must you return to the right?

Correct answer

Yes, return safely and gradually, signalling.

Yes. Return as soon as possible and gradually, without making others change course or speed, and signal, under article 85.3. Check mirrors and blind spots before moving laterally. Article 31 allows other lanes when traffic or road circumstances warrant it without obstructing following vehicles; another overtake is not the only possible circumstance. The absence of oncoming traffic does not justify habitually remaining in the left lane.
