House committee substitute to the 1st edition makes the following changes. 

Eliminates the proposed new Section 128 of Chapter VII of the Charter of the City of Durham (City), SL 1975-671, authorizing the City to employ Civilian Traffic Investigators. Instead enacts substantively similar, uncodified language granting the City of Durham the previously described authority set out in proposed Section 128 to employ and allow nonsworn personnel to investigate traffic crashes involving property damage only, named Traffic Crash Investigators (investigators; was, civilian personnel, named Civilian Traffic Investigators). Includes identical requirements of the City and investigators regarding the employment of investigators as previously proposed, with organizational changes, that involve establishing minimum employment standards and compliance with specified training conditions, equipment issuance, and limits of investigator authority. Similarly, specifies that investigators cannot be issued a weapon and have no authority to arrest or issue criminal process. Adds authority for an investigator to direct all traffic in conformance with law and, in the event of a fire or other emergency or to expedite traffic or to ensure safety, to direct traffic as conditions may require, in the same manner as a law enforcement officer. Maintains the requirement for the City to submit  a written report to the specified NCGA committees by December 31, 2023, on the training and use of investigators between the date the act becomes law and November 1, 2023. Changes the act's titles.
