Iimvavanyo zoLimo lweeNkalo ziyiqela leemvavanyo ezintathu ezisetyenziswe ngamapolisa ukuchonga ukuba ngaba umqhubi akakwazi. Imisebenzi yokuvavanya ibhalansi, ukulungelelaniswa kunye nokukwazi umqhubi ukuba ahlule ingqalelo ngaphezu komsebenzi omnye ngexesha lovavanyo lwengqondo.
Uvavanyo lwe-Standard Field Sobriety Test (SFST) ibhethri yeemvavanyo ezi-3 ezibandakanya umlingo onqamlekileyo we-nystagmus (HGN), ukuhamba-kunye nokujika, kunye nokuhlolwa komlenze omnye.
Ezi zivavanyo zenzelwe ukuba ziqinisekiswe ngokwenzululwazi ukuba ziqinisekise ukuxiliswa komthetho kwabaqhubi abatshutshiswayo ekuqhubeni utywala kwiimeko ezingama-90% ukuba zilawulwa ligosa eliqeqeshiwe. Iziphumo zovavanyo ziyavunyelwa njengobungqina enkundleni.
Ulawulo lwezokuPhepha kweSiThutho seNdlela kaZwelonke luchaza kwaye luchaza iinkalo ezintathu ze-SFST ngokubanzi:
I-Horizontal Gaze Nystagmus
I-nystagmus ye-horizontal eye-horizontal iyinto "yokugubungela" kwinto yenzeke kuwo wonke umntu xa amehlo ejikelezwa kwii-angles. Xa umntu exiliswa, ke, ukugubungela kwamehlo kuya kugxininisa kwaye kwenzeka kwiindawo eziphantsi.
Ukuguqula uvavanyo lwe-HGN, igosa liya kucela umqhubi ukuba alandele into ehambayo, njengepeni okanye i-flashlight, kancane kancane ukusuka kwicala ukuya kwelinye icala. Igosa lijongela ukuzimisela:
- Ukuba iliso alinakuyilandela into ngokufanelekileyo
- Ukuba ukuxubha kukwahlukileyo xa iliso liphambukile
- Ukuba i-angle yokugubungela ivela ngaphakathi kwama-45 degrees
Ukuba ezine okanye ezinye iinkcukacha zivela phakathi kwamehlo amabini, umqhubi unokuba nomxholo we-alcohol-alcohol (BAC) 0.10 okanye ngaphezulu. Uphando lwe-NHTSA lubonisa lo vavanyo ukuba luchaneke kwi-77% yezifundo zovavanyo.
Uvavanyo lokuhamba nokujika
Ukuvavanya ukuhamba nokujika, igosa licela umqhubi ukuba athathe amanyathelo ayisithoba, isithende-toe, kumgca ochanekileyo, vula inyawo elinye uze ubuyelele amanyathelo ayisithoba kwindlela echaseneyo.
Ngexesha lokuvavanya, igosa lijongela izibonakaliso ezisixhenxe zokukhubazeka:
- Ukuba ummangali akakwazi ukugcina ibhalansi xa ephulaphula imiyalelo
- Uqala phambi kokuba imiyalelo iphelile
- Ukuyeka xa uhamba ukuza kuhlaziywa
- Akuthinteli isithende
- Sebenzisa izixhobo ukulinganisela
- Ukulinganisela ngexesha lokujika
- Yenza inani elingalunganga lamanyathelo
Ukuba umqhubi ubonisa ezimbini okanye ngaphezulu kwezi ziboniso zingentla ngexesha lovavanyo, kukho amathuba angama-68% kwinqanaba le- BAC le-0.10 okanye ngaphezulu, ngokwe-NHTSA.
Ukuhlolwa kweMigangatho esisodwa
Ukuhlolwa kokuma komlenze omnye, igosa licela umqhubi ukuba ahambe ngonyawo olunye malunga neesentimitha ezintandathu ukusuka emhlabeni kwaye abaleke kwi-1,001 (enye-yewaka-enye, iwaka elinama-sibini, njl. Njl) de igosa lithi unyawo.
Ngexesha lemizuzwana engama-30 ezayo, igosa lijongela ezi ziboniso ezine:
- Ukutshintsha ngelixa belinganisa
- Ukusebenzisa iingalo ukulinganisela
- Ngethemba lokugcina ibhalansi
- Ukubeka unyawo phantsi
Ukuba umqhubi ubonisa ezimbini okanye ngaphezulu kwezi ziboniso ezingentla, kukho ithuba eli-65% lokuba ne-BAC ye-0.10 okanye ngaphezulu, ngokwe-NHSTA.
Ukuba umqhubi uyahluleka naluphi na olu luvavanyo lwenzululwazi olungenanto, igosa liya kucela ummangali ukuba athathe uvavanyo lokuphefumula okanye uvavanyo lwemichiza ukuqinisekisa ubungqina babo begazi.
Ezinye izizathu zokungaphumeleli iimvavanyo
Kukho izizathu ezininzi zokuba abantu abangaxilwanga bangenako ukuphumeza ngokuphumelelayo iimvavanyo ezingentla, kubandakanywa izimo ezithile zonyango, ukukhubazeka, ubudala, ukulimala, nokuthatha imithi ethile. Ukugqoka ii-lens zokudibanisa, umzekelo, kunokuchaphazela iziphumo zokuhlolwa kwe-HGN.
Igosa ngokuqhelekileyo liya kucela umqhubi ukuba kukho isizathu sokuba bangakwazi ukuphumeza uvavanyo baze benze ingxelo yabo impendulo kwingxelo yakhe yokubanjwa.
Ukuba kukho isizathu esivakalayo, unyango okanye ngenye indlela, kutheni unokwazi ukuhluleka enye okanye ubuninzi beengingqi zolu vavanyo lwezonyameko zokuqinisekisa ukuba uyayichaza ukuze igosa lenze ingxelo kwirekhodi esemthethweni.
Kungenokuba luncedo kuwe kwinkundla kamva.
Eyaziwayo njenge: Hamba umgca ochanekileyo, Hamba Uphendule Uvavanyo, Iimvavanyo Zendlela
Imizekelo: Nangona igosa lathi laphuza utywala, umqhubi wayedlulisa intsimi iimvavanyo ezintle. Ngoko igosa livumela umqhubi ukuba ahambe.
