The department has also written to RTOs that were behind on revenue targets through Dec for the current financial year.“With proper enforcement, road safety will improve and people will follow traffic norms too. Proper enforcement throughout the year automatically generates revenue for the department,” a senior official said.At a review meeting on Jan 22, the transport commissioner flagged widespread irregularities in private sleeper buses, saying action was visible only in Jaipur. The commissioner directed all district transport officers (DTOs) to take strict action.DTOs were told to verify permits and fitness certificates for all vehicles. Officials also indicated that IDs of inspectors generating the least revenue in each region could be suspended. RTOs in Bharatpur, Alwar, Jaipur (I), and Chittorgarh are lagging in revenue collection this year.
