Mu bisanzwe, amayunguruzo y’umuyaga arasubirwamwo inyuma y’ibilometero 10.000 gushika ku 20.000 canke amezi atandatu gushika ku mwaka umwe. Mu bibanza bikomeye (nk’inkungugu n’umwotsi), ivyo bikwiye kugabanywa bikaja ku bilometero 8.000 gushika ku 10.000 canke amezi atandatu. Ku mabarabara maninimanini, ivyo bishobora gushika ku bilometero 30.000.
Igihe co gusubirira akayunguruzo k’umuyaga gikwiye kumenyekana bivanye n’aho indege ikorera be n’ibiranga indege. Hashingiwe ku mirongo y’akayunguruzo k’umuyaga ka Dongfanghong ME454 (akayunguruzo k’umuyaga k’ubwoko bwumye- gashobora gusubirwamwo, igishushanyo c’intango), ubuhinga bwaco bw’akayunguruzo burafata neza inkungugu. Ariko rero, mu gihe c’igihe kirekire-igikorwa c’umuzigo munini- canke mu bidukikije vy’inkungugu, birakenewe ko umuntu asuzuma ikintu co kuyungurura ko ata nkungugu yirundanira amasaha 500 canke amezi atatu. Iyo urupapuro rwo kuyungurura ruhindutse rwirabura canke ubushobozi bwarwo bwo guca mu muyaga bugabanuka, rwoca rusubirwamwo ubwo nyene. Igicuncuro c’umuyaga c’umwimerere dutanga gifise igishushanyo c’icuma gihagaze kibereye umuderi wa 454. Ico kiyunguruzo kiroroshe gusubirizwa kandi kizanana n’igipfukisho c’icunguruzo ry’umuyaga kugira ngo kigabanye kwinjira kw’ibintu bininibinini. Ku bijanye n’iteraniro ry’iyunguruzo ry’umuyaga ry’ibarabara SG604 (rifise igikorwa co gutera umuriro mwinshi), kubera ko umubare w’amazi yinjira muri moteri ari munini, birakenewe ko uwusuzuma amasaha 300 canke amezi 2 yose.
