SIOUX FALLS, S.D. (AP) — Some taxi cab companies in Sioux Falls say a possible requirement that they provide service around the clock could put them out of business.

The Argus Leader newspaper reports that the City Council is considering the change.

First American Cab owner Todd Ellingson says it would put him out of business — along with all cab companies that operate with a single car and driver. Of the 22 cab companies in Sioux Falls, 15 have only a single car.

Yellow Cab is the largest company in town, with 24 cars and 38 drivers. Co-owner Tallie Kinsley says there are too many cab companies in town and the rules are too loose. She wants the city to set a minimum number of vehicles and employees a cab company must have.
