Security Chcking For Good, Security in Nepal

Of late, I have been seeing that police personnel are effectively involved in checking drunk-drivers on the roads. Such sights are more often seen after nine at night. They stop personal vehicles, both four wheelers and two wheelers, ask for the documents and check whether the drives are drunk. I am personally very happy with the move of the police. This can be benefiting the town in three ways. First, drunk-driving will be discouraged, second vehicle owner who travel without proper and updated documents will be forced to behave and third, accident rates will come down.
I have one concern, however. Like in the past I am afraid; this operation might go on for a few weeks or fortnights and cool down, like drives for quality food during festivals and drive against roadside vending some months back.
