House committee substitute amends the 1st edition as follows. 

Revises the requirements of the pilot program the City of Durham (City) is authorized to establish and implement pursuant to the act to use electronic speed measuring systems to detect speeding in school zones. Revises the provisions regarding required notice of criminal charges to the City, now requiring an officer that cites or arrests an owner or operator of a vehicle pursuant to GS 20-141.1, which prohibits speeding in a school zone, in accordance with GS 15A-302 and GS 15A-401 (was citing pursuant to 15A-302 and arresting pursuant to GS 15A-401, without reference to GS 20-141.1), in an area where an electronic speed-measuring system is in use for detecting speed limit violations to notify the City within 48 hours. More specifically provides that the City is not to issue a notification of violation under the act upon receipt of notification of the criminal charges, and prohibits imposing a penalty and requires a refund of penalties paid for a notification of violation issued in error following proper notice of criminal charges.
