Address:

Kolkata, West Bengal, 700060

Slot booking for Driving Test is not allowing in the site even after 45 days of passing the Learner Licence Test. The message which is coming is " Entered Application no is approved. Slot booking is not allowed. The application was done through Sarathi site and Learner's Licence Test was approved.

Cannot understand the reason for it. Have to give the driving test at the earliest and get the licence.
