Try to understand the probelm what exactly happened. The accident is not happenned by human mistake. Driver turn down the vehicle because of live electric wire across the road. If want to avoid this kind of accidents, Govt. should hire a commitee which has to strictly follow the road regulations (Checking the road quality, human load in vehicle, Electric tower & wire sag distance, vehicle quality etc..). It seems very diffucult. But this the right time to adopt.....
