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?

O le ta'avale 0 i le ata o lau ta'avale. E te fuafua e alu sa'o i se ta'amilosaga. E aga'i mai le uila afi X mai lou taumatau ma o le a kolosi le nofoaga e te ulu atu ai. O le ta'avale Y mai le ala lava lea e alu ese i lana auala muamua a'o le'i o'o i le nofoaga e te ulu atu ai; o le ta'avale Z mai le ala i le isi itu e alu ese fo'i e aunoa ma le kolosi o lou ala. O ai e tatau ona e tu'u i ai le avanoa?
