its not the first time we have seen this kind of incident involving container trucks. on this R/A for instance, there are at least 3 similar accidents that ive seen in the past.
there are plenty of safety issues concerning these heavy vehicles and cynbob just mentioned some of them. and unless these issues are resolved, we will be witnessing more of these on the roads.
...we just have to be very careful and keep a safe distance from these trucks.
