Two vehicles approach one another at an intersection. Both vehicles want to turn left. In what exceptional case do they have to turn one after the other?

Normally, when two vehicles approach an intersection from opposite directions and both want to turn left, they can turn simultaneously, often facing each other and passing in front of or behind each other. However, there are exceptions where this is not possible. If the current traffic situation (for example, pedestrians crossing, oncoming traffic, or other obstacles) or the physical design of the intersection (such as tight space or visibility issues) make a simultaneous left turn unsafe or impossible, the vehicles must turn one after the other. Therefore, answers 1 and 2 are correct. It is not solely about the equality of the priority at the intersection, but about actual circumstances requiring extra caution or order. Remember, safety and the situation on site always take priority over standard procedures.
