A week before Durga Puja, a Traffic Police Inspector during his beat in front of the Regional Transport Office at Padmapukur, Kolkata, noticed 120 brand new private Sedans, Hatchbacks and SUVs and 30, 4x4 wheelers, which had applied for new registration, queued up along the road in front of the Regional Transport Office to get registered. The vehicles and their owners were blocking up a substantial portion of the very busy road for about a kilometre, leading to traffic snarls.
On enquiry, the manager at the office showed the inspector on his desktop screen a currently updated table showing the data of the individual number of the four necessary documents whose verification has been completed, on all the private vehicles in queue. The manager explained that the time taken to verify the documents was causing the delay in registration.
