It has proved to be an expensive affair for auto rickshaw drivers of Navi Mumbai, who failed to recalibrate the meters of their three-wheelers on time. They had to pay a hefty sum of Rs 700 as part of a month-long drive conducted by transport officials of Vashi Regional Transport Office (RTO).

According to RTO officials, last month out of 9,750 autos in the satellite town, over 1,850 autos were yet to recalibrate the meters.
