I-bumper inomsebenzi wokukhusela ukhuseleko, ukuhombisa kunye nokuphucula iimpawu ze-aerodynamic zesithuthi. Ngokwembono yokhuseleko, imoto inokudlala indima ye-buffer xa kwenzeka ingozi yesantya esiphantsi, ukukhusela umzimba wemoto yangaphambili neyangasemva; Xa kwenzeka iingozi kubahambi ngeenyawo inokudlala indima ethile ekukhuseleni abahambi ngeenyawo. Ngokwembonakalo, iyahombisa kwaye iba yinxalenye ebalulekileyo yembonakalo yemoto yokuhombisa. Kwangaxeshanye, ii-bumper zemoto nazo zinefuthe elithile le-aerodynamic.
Kwangaxeshanye, ukuze kuncitshiswe umonakalo kubantu abakwiimoto xa kukho iingozi ezibangelwa ziingozi, iimoto zihlala zixhotyiswe ngeebhampa zomnyango ukuze zonyuse amandla okungqubana kweengcango. Le ndlela iyasebenza, ilula, ayitshintshi kangako kwisakhiwo somzimba, kwaye isetyenziswa kakhulu. Kwasekuqaleni koMboniso weeMoto waMazwe ngaMazwe waseShenzhen ngo-1993, kwavulwa ucango lwemoto ukuze kubonakale i-bumper ukuze abaphulaphuli bayibone, ukubonisa ukusebenza kwayo okuhle kokhuseleko.
Ukufakelwa kwebhampa yomnyango kumnyango ngamnye wepleyiti yomnyango ethe tye okanye ebhityileyo, idlala indima yebhampa yomva yemoto engaphambili, ukuze yonke imoto ijikeleze "ukhuseleko" lwebhampa, yenze "udonga lwentsimbi", ukuze umntu ohlala emotweni abe nendawo ekhuselekileyo. Kakade ke, ukufakelwa kweebhampa zomnyango ezinjalo ngokuqinisekileyo kuya kunyusa iindleko ezithile kubavelisi bemoto, kodwa kubantu abahleli emotweni, ukhuseleko kunye nokuzithemba kuya kwanda kakhulu.
