Ubuwazi ukuthi umuntu ojwayelekile ohlala eMelika uvezwa amakhulu, kwesinye isikhathi izinkulungwane zezimpawu zokuthunyelwe nganoma yiluphi usuku olunikeziwe? Lezi zimpawu zisetshenziselwa cishe zonke izimpawu zethrafikhi ozozibona emgwaqeni. Abantu abaningi bavame ukungakunaki ukubaluleka kwalezi zimpawu nokuthi zisiza kanjani ukukhulisa izinyathelo zokuphepha. Izinhlobonhlobo zokuthunyelwe ziyatholakala zokufaka izimpawu zomgwaqo. Ezinye zezikhala zihlanganisa i-Square Steel, iRound Steel, i-U-Channel Steel kanye ne-Wooden Posts.

Okuthunyelwe Kwezimpawu Eziyindilinga zifana ncamashí nawe ongazicabanga ukuze zibukeke njengeshubhu lensimbi eliyindilinga. Lokhu okuthunyelwe kuvame ukuba yimisebenzi eyonga kakhulu kwezomnotho njengoba kubiza kancane futhi kusebenza kahle. Izimpawu zivame ukunamathiselwa ngqo eposini noma ziboshelwe kupharamitha yangaphandle yeposi okuvumela ukuba kube lula ukuhlanganisa.

Izikhala Zezimpawu Eziyisikwele ziyafana nezazo ezinomumo oyindilinga, kodwa zinesimo esiyisikwele esivumela ukuqina okwengeziwe. Lokhu okuthunyelwe kuvame ukuba namandla kakhulu futhi kunokuningi ongakwenza uma ukhweza uphawu kulolu hlobo lokuthunyelwe. Uvunyelwe futhi ukukhweza izimpawu ezengeziwe eposini njengoba kukhona izinhlangothi ezi-4 ezihlukene onokufinyelela kuzo. Lezi zizathu kungani lokhu okuthunyelwe ngezinye izikhathi kubiza kakhulu kunozakwabo.

Okuthunyelwe kwe-U-Channelziyisisekelo semboni yezimpawu zethrafikhi. Lokhu okuthunyelwe kudinga ukulungiswa okuphansi futhi kusetshenziswa izinhlobo eziningi zezinkampani futhi kuyinketho edume kakhulu. Abiza kahle, aqinile futhi ayasebenza. Lezi zimpawu zokuthunyelwe zenzelwe ukufaka okulula nokulula ngaphandle kokuba nomthamo omkhulu wokulayisha.

Lokhu Okuthunyelwe Kwezimpawu kungafakwa kalula ngokusebenzisa Umshayeli Weposi. Kungakhathaliseki ukuthi lokho kube Umshayeli Weposi Wezandla noma Umshayeli Womoya Ocindezelwe. Zenzelwe ukwenza umsebenzi ube lula kuwe. Uma i-Post ifakwe kahle, i-Traffic Sign ibonakala kalula emgwaqeni evumela abashayeli ukuthi bazi ngokugcwele indawo ebazungezile.
