Passing ahead of one or a few vehicles in motion, without leaving the lane occupied✓Правильный ответ
Passing ahead one or a few vehicles in motion, in relation to leaving the lane occupied
Объяснение
Bypassing is moving ahead of one or more vehicles that are in motion while remaining within the lane already occupied. Leaving that lane is the distinguishing feature of a different passing manoeuvre, so it does not belong in this definition.
