Tenn. Code Ann. § 54-1-404

Upon receipt of the information required by § 54-1-403, the department of transportation may verify the reported motor vehicle registration number through the department of safety. Upon completing verification, if possible, the department of transportation may mail a letter to the owner or lessee of the motor vehicle at the address affiliated with the registration number. The letter may inform the owner or lessee of the motor vehicle that a concerned citizen has reported witnessing the commission of a littering offense from the motor vehicle. The letter may strongly discourage the owner or lessee from committing a subsequent littering offense or allowing a subsequent littering offense to be committed from the person's motor vehicle and warn the owner or lessee of the penalties for littering under Tennessee law.
