Our motorway police is only about speed gun measuring the speeds of the vehicles at few points on the motorway. Equipped with a speed gun *** a camera and a chair, they usually ambush the innocent drivers rather than try to nab the violators involved in other major traffic violations which are far more dangerous than mere over-speeding such as drunk driving, land changes, tailgating etc etc probably because over-speeding is the easiest of the to catch and by the motorway police.
Our traffic police is also not trained and lack required equipment to monitor and track drunk drivers.
