With three weeks remaining until all D.C. cabs are required to power up their time and distance meters, few of the city’s roughly 7,000 licensed taxi drivers have had the equipment installed in their vehicles.

Drivers still haven’t been told where or how to have the work done, and the D.C. Taxicab Commission’s Web site does not list the names of licensed meter installers. The taxi industry appears unprepared to ditch the zone system come May 1 in lieu of the meters used in virtually every major U.S. city.
