Disclaimer: I am NOT a lawyer, nor will they allow me to portray one on TV
When operating a motor vehicle the driver is required to have a valid (read original, referencing your question) driver's license on his/her person. A copy is not legal under the letter of the law in the state of Texas, though the temporary paper copy issued by the DPS is valid till issuance of permanent card.
Although Texas does not currently have a so called "stop and identify" law that I am aware of, there is this statute:
Texas Penal Code, Title 8, §38.02(a)A person commits an offense if he intentionally refuses to give his name, residence address, or date of birth to a peace officer who has lawfully arrested the person and requested the information.
A traffic citation also constitutes "arrest" in application of this statute. Having a bubble light and speeding to a fire, it may behoove you to carry proper ID to avoid being detained while awaiting verification.--
