Imiyoboro isusurutsa imiyoboro yo munsi yubutaka EN10219
IbyacuImiyoboro Yasuyenigisubizo cyiza kumishinga aho kurwanya ruswa nubunyangamugayo bwimiterere nibyingenzi. Inzira yo gusunika isukura ntabwo yongerera imbaraga umuyoboro, ahubwo itanga ubuso butagira ingano, bugabanya ibyago byo kumeneka no gutsindwa. Ibi bituma bikwiranye cyane cyane nibidukikije bikaze bikunze kugaragara mubikorwa byubutaka.
Ibipimo bya EN10219 byemeza ko imiyoboro yacu ikorerwa neza kandi ireme, iremeza ko ishobora kwihanganira imikazo n'ingorane zo gutwara abantu. Yibanze ku Kuramba no kwizerwa, imiyoboro yacu isutse yateguwe kugirango itange imikorere ndende, kugabanya ibikenewe kubungabunga no gusimburwa.
