Outside a built-up area, a car finishes overtaking on a carriageway with three lanes in its direction. It can safely return to the right lane and has no need to continue overtaking; another vehicle follows. Must it return to the right lane?

Correct answer

Yes, so as not to obstruct the vehicle following it.

Yes; return to the right without danger or obstructing following traffic. Articles 31 and 85.3 require normal right-lane use and returning after overtaking when safe. On carriageways with at least two lanes per direction, a driver may continue overtaking in the left lane without returning between manoeuvres if not obstructing faster following traffic. That circumstance is excluded here; an available lane to the left does not authorise unnecessarily remaining in the middle lane.
