A sub-inspector issued me a traffic challan. I thought only someone higher like a Head Constable could do that. What are my options? Should I approach the Traffic Police Commissioner or a specific Magistrate?

A Sub-Inspector has the authority to issue traffic challans in India. You can challenge the challan by appealing to the designated authority within the stipulated time frame. This usually involves filing an appeal with the concerned Traffic Police Commissioner or a designated Magistrate.
