First thing is, India does not follow a uniform structure of issueing Driving Licence; every state has its own style and system. This the biggest fault resulting increased number of accidents and voilation of traffic law. The Central Govt.must structure this, simliar to issue of Passport.
Any drunk driver detained for breaking the law, his or her licence must be cancelled for 5(five ) years; fresh licence should be issued with a garuntor and surety. This should apply to all type of automobile;whether two wheeler or four.
Repeat offence should amount to 10(ten) year Ban for licence eligibility; as well vehical confistication. Unless these systmes are incorporated the number of crime will increase and enforcement agencies will have field day in bribe taking.
