Ukukhanya kwe-brake ephezulu kufakelwa kwinxalenye ephezulu yemoto, ukuze imoto iqhube ngasemva kulula ukuyibona ngaphambili i-rake yemoto, ukuthintela ingozi yokuphela kwemoto. Kuba imoto ephakathi sele inezibane ezimbini ze-brake ezifakwe ngasemva kwemoto, enye ishiyekileyo kunye nelungelo elinye.
Ukukhanya okuphezulu kokukhanya kuyabizwa kukukhanya kwesithathu, ukukhanya okuphezulu kokukhanya, ukukhanya kwesithathu. Ukukhanya kwebhuleki ephezulu kusetyenziselwa ukulumkisa imoto ngasemva, ukuphepha ukungqubana kwasemva.
Izithuthi ngaphandle kwezibane eziphezulu eziphezulu, ngakumbi iimoto kunye neemoto ezincinci xa kukhala zisezantsi ze-Brae, eziqheleke ukuba zikhanyise iilori ze-brake ngasemva, iibhasi kunye neebhasi ezinamaxesha amaninzi kunzima ukubona ngokucacileyo. Ke ngoko, ubungozi obufihliweyo bokungqengqa ngasemva bukhulu kakhulu. [1]
Inani elikhulu leziphumo zophando libonisa ukuba ukukhanya okuphezulu kwe-brake kunokuthintela ngokufanelekileyo kwaye kuncitshiswe ukuvela kokungqubana kwesiphelo. Ke ngoko, izibane eziphakamileyo zokuqhekeza zisetyenziswa kakhulu kumazwe amaninzi aphuhlileyo. Umzekelo, eUnited States, ngokwemigaqo, zonke iimoto ezisandul 'ukuthengiswa kufuneka zixhotywe ngezibane eziphezulu ze-brake ukusukela ngo-1986. Zonke iilori ezikhanyayo zithengisiwe ukusukela ngo-1994 kufuneka zibe nezibane eziphezulu zeBrake
