Matoorada wax shiida
Dareewalada casriga ah, labadaba dabka dhimbiil iyo shidista, uma baahna in la jebiyo macnihii hore ee ereyga.
Markaa ma jirto baahi loo qabo in la beddelo saliidda oo la shaandheeyo ama la hagaajiyo valves ka dib 1000 - 1500 km ee orodka. 
Matoorada casriga ah, kormeerka ugu horreeya ee isbeddelka saliidda ayaa dhacaya, iyada oo ku xidhan shuruudaha soo-saaraha, ka dib 15, 20 ama 30 kun oo kilomitir ama ka dib hal sano oo hawlgal ah, hadba kii soo hormara.
Si kastaba ha ahaatee, waa in la caddeeyo in matoorada casriga ah ee xilliga ugu horreeya ee shaqada (qiyaastii 1000 km) aan lagu qaadin culeyska baabuurka ee ku socda xawaare hooseeya iyo gawaarida sare, waana inaan si adag loogu dhejin xaalad qabow isla markiiba ka dib marka la bilaabo. Qaybaha is jiid jiidka ee matooradan aadbay ugu saxsan yihiin mishiinada, laakiin waa in ay is waafajiyaan oo ay is waafajiyaan midba midka kale, waxna ka taraya masaafada mustaqbalka.
