Umzimba wemoto ngokubanzi uneentsika ezintathu, ikholamu engaphambili (ikholamu A), ikholamu ephakathi (ikholamu B), ikholamu engasemva (ikholamu C) ukusuka ngaphambili ukuya ngasemva. Kwiimoto, ukongeza kwinkxaso, ikholamu ikwadlala indima yesakhelo somnyango.
Ikholamu engaphambili yikholamu yoqhagamshelo ekhohlo neyasekunene edibanisa uphahla nekhabhathi engaphambili. Ikholamu engaphambili iphakathi kwendawo yenjini kunye nekhabhathi, ngaphezulu kwezipili zasekhohlo nasekunene, kwaye iya kuvala inxalenye ye-horizon yakho yokujika, ngakumbi xa ujika ngasekhohlo, ngoko ke kuxoxwa ngakumbi ngayo.
I-Angle apho ikholamu engaphambili ivala khona umbono womqhubi kufuneka iqwalaselwe xa kujongwa i-geometry yekholamu engaphambili. Kwiimeko eziqhelekileyo, umgca wokubona womqhubi ngekholamu engaphambili, i-binocular overlap I-Angle yetotali yi-5-6 degrees, ukusuka kwintuthuzelo yomqhubi, okukhona i-Angle edlulayo incinci, kokukhona ingcono, kodwa oku kubandakanya ukuqina kwekholamu engaphambili, kungekuphela nje ukuba ibe nobukhulu obuthile bejometri ukugcina ukuqina okuphezulu kwekholamu engaphambili, kodwa nokunciphisa impembelelo yokuvaleka komgca wokubona womqhubi, yingxaki ephikisanayo. Umyili kufuneka azame ukulinganisela ezi zimbini ukuze afumane iziphumo ezilungileyo. KwiMboniso yeeMoto zaMazwe ngaMazwe yaseMntla Melika ka-2001, iVolvo yaseSweden yaqalisa imoto yayo yamva nje ye-SCC. Ikholamu engaphambili yatshintshwa yaba yimo ecacileyo, egqunywe ngeglasi ecacileyo ukuze umqhubi akwazi ukubona ihlabathi langaphandle ngekholamu, ukuze indawo engaboniyo yentsimi yombono incitshiswe ibe ncinci.
