The formulation of these regulations does not preclude the Public Service Commission from altering or amending them in whole or in part, or from requiring any other additional service, equipment, facility, or standard, either upon complaint or upon its own motion, or upon the application of a taxicab owner. Furthermore, these standards do not relieve an owner or operator of a taxicab from any of his duties under any orders of the Public Service Commission which are not in conflict with these regulations under the laws of this State.
