Vastavam web: The traffic police in Maharashtra have started digitalising the `challan’ (fine) system. A challan refers to the receipt for fine recovered for traffic rule violation. The first phase of the `One State One e-challan’ initiative is being rolled out in commissionerates of Mumbai, Nagpur, Navi Mumbai, Thane, Pune and Pimpri Chinchwad, the traffic police said in a press note Wednesday. Other parts of the state would be covered in the next phase, it said. Under the scheme, a person who has been `challanned’ can pay the fine on `mahatrafficechallan.gov.in’, the note said.
