How big a police presence can prevent more accidents ? Can we have a police follow every big commercial vehicle ? This is unrealistic.
It seems that bigger commercial vehicles are a bigger risk than smaller private cars. Perhaps the ministry of transport can work with bus companies and some of the big commercial vehicles companies to develop a more comprehensive safety training for big vehicles. Make such a safety training compulsory and showing cause of past accidents to help drivers avoid these types of accidents. After the training has been developed, all big commercial vehicles drivers must take the training within 6 months.
During training, showing past accidents and pictures of lives lost like the 2 kids recently may be able to instill some sense of responsible driving on these drivers. We can also show these commercial drivers the severe penalties that are meted out to past offenders to compell them to respect the law and the safety of other road users. Show all past cases to drive the message of responsible driving. This may drive some sense in them to be careful and not speed recklessly. If we repeatedly show them that they can go to jail for reckless driving, I am sure most will wake up. It's not just driving skill but correct attitude is also a major factor.
