In the 2014 Tennessee Legislative session the Tennessee Legislature decided to clarify exactly what constitutes a red light violation in Tennessee. The legislature amended T.C.A. § 55-8-110 which is the statute that discusses what traffic control signals mean for an intersection. It defines and explains the meaning of the “green”, “yellow”, and “red” notifications on traffic signal devices. The Tennessee Legislature passed Public Chapter No. 989 that added a new subsection (e) to T.C.A. § 55-8-110 as follows:
(e) It is not a violation of subdivision (a)(3), unless the front tires of a vehicle cross the stop line after the signal is red.
