I have used this road numerous of time by bus normally ...I heard one of the survivors claim there was a strong smell of clutch burning,,,this might be the reason for the accident..the driver tried to engage a low gear....which many buses engage just b4 ascending the subuiga hill...if you are late and you try to engage it on the hill itself then be prepared to drive at high speed as this will fail...breaks will also not help as they will overheat...the only way the driver could have avoided this collision was by Gods grace.
overloading might not be the case as it was a long trip and any student will raise this issue...Signage is the only thing that can be blamed on this accident...its hard to know how steep the subuiga hill is unless you are on it.
