Blue is leaving the route of a marked centre line at this junction. Red B follows that continuing marked route towards blue. Green A waits on the side road behind a GIVE WAY sign. Their shown paths conflict. To whom must blue give way?
蓝车在这个路口驶离道路中心线所标示的路线。红车B沿该贯通标线路线迎面驶来，绿车A在支路的GIVE WAY让行标志后等候。图示路线存在冲突。蓝车必须让谁？
Blue gives way to B because leaving the marked centre-line route counts as turning. A faces GIVE WAY and must yield to conflicting vehicles on the uncontrolled continuing road, including blue.
蓝车驶离中心线所标示的路线，属于转弯，因此须让行沿该路线行驶的B。A面对GIVE WAY标志，须让行贯通道路上与其路线冲突的车辆，包括蓝车。

The apparent shape of the road does not replace the marked route or traffic controls. This is blue’s give-way obligation, not a complete order in which all three vehicles must travel.
应按标线指示的贯通路线和实际交通控制判断，而不是只看道路形状。本题问蓝车的让行义务，并未规定三辆车的完整通行先后顺序。
