Marka roob yar yar ay tahay — sida loo joojiyo tiraha inaysan xiriirka jidka miska.
Hydroplaning (aquaplaning) waxaa dhacda marka tira aysan karinimatin biiga dhinacyada u turjin dhakhso. Baabuurku wuxuu bilaabaa inuu slideeysto biig jajab ah oo graspu dhammaantood ba meel ka baxdo. Aad loo arko: • Luqunta 80 km/h ka sareeya • Joogga biiga 4 mm ka sareeya • Tiraha la baabaajiyay (tread depth 3 mm ka hoose) • Jilxooyinka lugga wayn oo biiga soo uruuriya
Haddii aad daacisid hydroplaning: • Gasiga calacali ka dhig: HA joojin adkaadii • Aoda rasta jog: iska dhaafi guddooyinka degdeg ah • Su'aasho illaa tira ay dib u xiriiraan (ilbiriqsi yar) • Markaas kaliya ayaad joojin ama guddoon karaysaa si caadi ah
Qaboojida iyo tayyaaraha intaa oo dhami leh dhawr sipes ayaa yar yar khatarta hydroplaning iska dhigta inta la eego tayyaaraha xagaaga. Waxan waa jawaab fogaanin – dooro tayyaaraha saxda ah markaa haddii aad sooco, maqan markaa aad soocdo. Sensor rooba oo ku jira gaari casri ayaa si toos ah u kordhinaya lug windscreener xaladda roob kulul, muujinaysa sida roobdu ay u adag tahay – qalab lug, maqan taliyaan sooca. Hadii roobdu ay kordho: yar yar lug oo iska daag masaafad badan gaariga hoose. Lug yar yar waxay yar yar karti kara khatarta marka qalab tayyaarada ay guur karto jidka; masaafad dheer ayaa siinaya waqti dhawr ah oo jawaabka hadii jidka ay noqoto jecel-miis.
Roob adag: lua luqunta 60–70 km/h illeen haddii calaamadu ay tibiyaan 90, iska dhaaf adapted speed lesson-ka Xawaaraha iyo masaafada. Hydroplane event 90 km/h-da marka badan wuxuu dhammaadaa skid ama run-off-ga.
