All charges for taxicab service shall be calculated and indicated by a taximeter, and at all times while the taxicab is engaged the flag of the taximeter shall be thrown into a position to register charges for mileage, or into a position to register charges for waiting time. No taximeter shall be used whose mechanism will register a combined charge for mileage and waiting time in any single position, and no taximeter shall be so operated as to cause any charge to be registered thereon except during the time while the taxicab is engaged by a passenger.
