The fundamental cause is lack of traffic sense. People tend to overtake, irrespective whether, there is space or no and do not even bother to blow the horn while overtaking. The tendency to jump signals is another cause for accidents and chaos on the roads.
Lane driving is not observed. Talking in the cell phone while driving is another menace.
Youth should give a though on over speeding. The traffic problem cannot be solved by the police alone, it should be taken up collectively.
