After overtaking the car and the lorry, does the green car wish to continue overtaking other vehicles? Must it return to the right-hand lane first?

Correct answer

Yes, if it inconveniences other drivers approaching from behind at a higher speed.

After overtaking the car and the lorry, the driver of the green car must return to the right-hand lane if remaining in the left-hand lane inconveniences other drivers approaching from behind at a higher speed. On roads with at least two lanes in each direction, a driver may remain in the lane used for a previous overtaking manoeuvre if they intend to overtake again. However, they must ensure that this action does not unduly inconvenience drivers approaching more quickly from behind. If there is no other vehicle to overtake immediately, or if the presence of the green car in the left-hand lane prevents faster vehicles from travelling normally, it must return to the right-hand lane.
