Can I drive a commercial vehicle with a normal drivers license?

Can I drive a commercial vehicle (a taxi),i.e. a car with a yellow number plate with a normal drivers license if I do not carry a passenger with me? Elaborating the case: I'm planning to own yellow board sedan and employ a driver with a commercial license to act as the cab driver. My query is whether I can drive the same once in a while to get from one place to another provided I don't carry another passenger with me. Is that possible in any way??
