Vehicle 0 in the diagram is your vehicle. You intend to travel straight through a roundabout. Motorcycle X approaches from your right and will cross your entry. Car Y from that same approach takes its first exit before your entry; car Z from the opposite approach also exits without crossing your path. Which must you give way to?

圖中0號車是你的車。你準備直行通過環島。摩托車X從右側駛來並會穿過你的入口。同側的小汽車Y在到達你的入口前從第一個出口駛出；對面的Z也從不與你相交的路線駛出。你應讓誰？
