Umzimba wemoto ejwayelekile unamakholomu amathathu, ikholomu yangaphambili (ikholamu), ikholomu ephakathi (B ikholamu), ikholomu engemuva (ikholomu yesemuva (ikholomu ye-C) kusukela phambili kuya emuva. Ezimotweni, ngaphezu kokusekelwa, ikholomu nayo idlala indima yohlaka lomnyango.
Ikholomu yangaphambili yikholomu yokuxhumeka yangaphambili yesobunxele nesokunxele exhuma ophahleni kwikhabethe langaphambili. Ikholomu yangaphambili iphakathi kwegumbi lenjini kanye ne-cockpit, ngaphezulu kwezibuko zesobunxele nakwesokudla, futhi izovimba ingxenye yomugqa wakho wokujika, ikakhulukazi ekujikeni kwesokunxele, ngakho-ke kuxoxwa ngakho okuningi.
I-angle lapho ikholomu yangaphambili ivimba khona umbono womshayeli kufanele futhi ibhekwe lapho kucatshangelwa i-geomtry yekholamu yangaphambili. Ngaphansi kwezimo ezijwayelekile, umugqa womshayeli wokubona ngekholamu wangaphambili, i-anglelap angle ye-binocular yenani lingama-5-6 degrees, okungcono, kepha lokhu kufaka phakathi ukuqina kwe-geometric, kuyinkinga yokushayela i-Occlusion Ithonya, kuyinkinga yokuphikisana. Umqambi kufanele azame ukulinganisa lokhu okubili ukuthola imiphumela emihle. E-2001 North American International Auto Show, iVolvo yaseSweden yethule imiqondo yayo yakamuva ye-SCC. Ikholomu yangaphambili iguqulwe yaba yifomu elibonakalayo, elinamathele ngengilazi esobala ukuze umshayeli akwazi ukubona umhlaba wangaphandle ngekholomu, ukuze indawo eyimpumputhe yensimu yombono yehliswe ibe yincane.
