Akabati gafite inshingano zo kurinda umutekano w'imodoka, gushushanya ikinyabiziga no kunoza imiterere y'ikirere. Mu bijyanye n'umutekano, ikinyabiziga gishobora kugira uruhare mu gihe cy'impanuka y'umuvuduko muto no kurinda umubiri w'imbere n'inyuma; gishobora kurinda abanyamaguru mu gihe cy'impanuka ku banyamaguru. Mu bijyanye n'isura, ni gushariza kandi kabaye igice cy'ingenzi mu gushariza imiterere y'imodoka; Muri icyo gihe kandi, akabati gafite ingaruka ku kirere.
Muri icyo gihe, kugira ngo abagenzi bagabanye imvune mu gihe habaye impanuka ku ruhande, ubusanzwe hashyirwaho agapfukamunwa k'urugi kugira ngo kongere imbaraga zo kurwanya impanuka z'urugi. Ubu buryo ni ingirakamaro kandi bworoshye, nta mpinduka nyinshi ku miterere y'umubiri, kandi bwakoreshejwe cyane. Kuva mu imurikagurisha mpuzamahanga ry'imodoka rya Shenzhen mu 1993, Honda Accord yafunguye igice cy'urugi kugira ngo yerekane agapfukamunwa k'urugi ku bari aho kugira ngo berekane imikorere yabwo myiza mu mutekano.
Gushyiramo bumper y'umuryango ni ugushyira imirimbo myinshi ikomeye y'icyuma itambitse cyangwa itambitse mu gice cy'umuryango cya buri rugi, ikigira uruhare rwa bumper y'imbere n'inyuma, kugira ngo imodoka yose "iherekezwe" n'udupira tw'imbere, inyuma, ibumoso n'iburyo, bikore "urukuta rw'umuringa n'urukuta rw'icyuma", kugira ngo abagenzi b'imodoka bagire ahantu hatekanye cyane. Birumvikana ko gushyiraho ubwoko bw'udupira tw'umuryango nta gushidikanya ko byongera ikiguzi ku bakora imodoka, ariko ku bagenzi b'imodoka, umutekano n'umutekano bizarushaho kwiyongera cyane.
