Traffic violation

Hello This is perhaps too simple a question. Day before yesterday at 5 p.m., I was booked by a traffic sergeant in Kolkata for violating a one-way restriction. I had indeed overlooked the road sign by mistake. He wrote fine of Rs. 2000/- under Section 115/194 on a form that lists MVA, 1988, WBMVR, 1989 & CMVR, 1989. Then he gave me a copy of the filled-in form and confiscated my driving licence. Now it seems Sections 115 and 194 pertain not to traffic violations but quite different things in both WBMVR, 1989 (see e.g. https://wbxpress.com/wp-content/uploads/2013/09/WB-MOTOR-VEHICLE-RULES-1989.pdf) and CMVR, 1989 (see e.g. http://www.tn.gov.in/sta/Cmvr1989.pdf). Thus it appears that only MVA, 1988 might apply. But as per the link http://www.indiandrivingschools.com/traffic-offences-and-penalties.php, as also several other websites, even in MVA, 1988 it is not Sections 115/194 that apply for violations of one-way restrictions but Section 177 and the fine is just Rs. 100/-. I visited the relevant traffic guard (Shyambazar Traffic Guard) yesterday but could not convince the on-duty persons there that there was any mistake on the part of the police. They asked me to visit again next week for paying the Rs. 2000/- fine and retrieving my licence. Could you please advise what my course of action should be? Thanking in anticipation, Arindam Sengupta Kolkata
