First of all the issue of identifying the drunken drivers. This can be done easily, with setting up of check post or conducting surprise check at 1km on either side of any bar. Drunken driving can be easily identified.
Punishment of drunken driving - When it is obvious that driving after consuming alcoholic drinks is not permitted, anybody caught, should be ruthlessly, punished to the extent of cancelling the driving licence and secondly, making a note in the RC of the vehicle in which they were driving. On second time the same vehicle being caught, the registration of the vehicle should be cancelled. This should be treated more seriously as value of life is much greater then the cost of the vehicles or the contribution of these anti social elements who drive after consuming alcoholic drinks.
