Red Light Camera Delay Interval.

HB 189 clarifies the timing requirements for red light cameras in North Carolina, ensuring they only issue tickets after the red light has been displayed for a legally required period. The bill specifies that cameras cannot enforce violations for vehicles entering an intersection before the red clearance interval expires (the time after the light turns red before the camera can activate). It requires all traffic signals with cameras to follow engineering plans approved by a licensed professional engineer and comply with the standard Manual on Uniform Traffic Control Devices. This affects municipalities using red light cameras under state law, setting clear technical standards for when violations can be recorded.
