New taxi fare rates will go into effect on April 21, 2012. All meters will “not” be re-calibrated to reflect the change by April 21, 2012.  Taking this into consideration, drivers may continue to operate under the old rates until re-calibration or the May 31, 2012 deadline.  Citations will not be issued during this timeframe.   All re-calibrated meters will have a red DCTC Seal attached.  Meters must be used for “all” fares. Rate 1 shall be used unless a Snow Emergency has been declared for Rate 3 or Hourly Hire for Rate 4.  Rate 2 has been abolished.  Meter-generated receipts are the only valid receipts permitted and shall be made available upon passenger’s request.
