Qufulka albaabka hore ee albaabka gawaarida waa qufulka albaabka ee albaabka, kaliya loo isticmaalo ka hortagga in albaabka gaariga uu si otomaatig ah loo furo markii shilka, kaliya uu ka ciyaaro kaalin badbaado wadis ah, oo aan ahayn doorka anti-daft. Iyada oo ay la socoto horumarka bulshada, horumarinta sayniska iyo tikniyoolajiyadda iyo kororka joogtada ah ee lahaanshaha gaariga, albaabada gawaarida iyo gawaarida xamuulka ah ee la soo saaray ayaa mar dambe ku qalabaysan albaab albaab ah.
