Icyifuzo cya mbere kandi kigaragara cyo gukoresha indorerwamo zikurura ni ukureba ko zifite isuku.Niba uherutse kugira ibyaweikinyabiziga gikururahanze kumuhanda, birashoboka ko umwanda mwinshi, ivumbi cyangwa ibyondo byabonye inzira byindorerwamo.Hamwe nindorerwamo zanduye, kugaragara biragabanuka cyane kandi byongera amahirwe yo gutera impanuka mugihe uhindukiye, usubira inyuma cyangwa uhindura inzira.

Ingano yindorerwamo ni ngombwa - nini, nziza.Amategeko rusange avuga ko kuri buri metero 10 (metero 3) z'uburebure bwikinyabiziga muri rusange (iyo niyo modoka ikurura hamwe nikinyabiziga gikururwa cyongeweho hamwe), indorerwamo zawe zigomba kuba zifite santimetero imwe (santimetero 2,5).Kubwibyo, ikinyabiziga gifite uburebure bwa metero 50 (uburebure bwa metero 15) kigomba kugira indorerwamo ya santimetero eshanu (santimetero 13).Niba uhangayikishijwe no gukubita cyangwa gusiba indorerwamo zawe ukanda cyane, urashobora kugura izisubira inyuma kuruhande rwikinyabiziga.

Uzashaka kwemeza ko indorerwamo zitagutse gusa, ariko kandi ndende bihagije.Ubugari bwagutse bw'indorerwamo zikurura, cyane cyane iyo zerekejwe gato ku kinyabiziga, zemerera abashoferi kubona intera nini inyuma yabo.Gutwara ibinyabiziga nabyo mubisanzwe birebire kuruta izindi modoka kumuhanda.Indorerwamo rero igomba no kwerekana byinshi mubutaka munsi yumushoferi bishoboka.Ibi biteza imbere ibibanza bihumye kandi byongeye byongera umutekano wumwana, kubera ko utuntu duto akenshi usanga ari duto cyane ku buryo tutabona imbere mu gikamyo.

Guhindura indorerwamo zawe zikurura kumwanya ukwiye nabyo ni ngombwa cyane.Hamwe nindorerwamo muburyo bugororotse, perpendicular kumodoka, icara kuntebe yumushoferi hanyuma utangire uhindure indorerwamo yibumoso.Niba ushoboye kubona metero 200 (metero 61) cyangwa zirenga inyuma yibumoso bwikinyabiziga, ugomba kuba witeguye.Kora kimwe kuruhande rwiburyo, ongera wicare ku ntebe yumushoferi, gusa iki gihe, ugomba kugira umuntu ugufasha guhindura indorerwamo.
