On a two-lane road running in the same direction, if after overtaking you are going to carry on overtaking, can you continue driving in the left-hand lane?

Correct answer

Only if it does not unduly hinder vehicles travelling behind at a higher speed.

On a road with two lanes in the same direction, if a driver has overtaken and plans to continue overtaking, they may continue driving in the left-hand lane, but only if doing so does not unduly hinder vehicles travelling behind at a higher speed. In other words, the driver may remain in the left-hand lane used for the previous overtaking manoeuvre provided they make sure not to obstruct the normal flow of traffic. This rule is intended to ensure efficient use of the lanes and to avoid situations where the left-hand lane is left unnecessarily occupied, causing possible tailbacks or hazardous situations. If there are no vehicles to overtake immediately, or if their presence in the left-hand lane prevents the smooth passage of faster vehicles approaching from behind, the driver must return to the right-hand lane.
