House committee substitute to the 2nd edition makes the following changes. 

Eliminates the proposed changes to GS 20-157(f), which made it a Class 3 misdemeanor for a driver to fail to, as appropriate, either move the vehicle into a lane that is not the lane nearest a parked or standing authorized emergency vehicle or public service vehicle or slow the vehicle and drive at a reduced speed and be prepared to stop until completely past the authorized emergency vehicle or public service vehicle when the emergency or public service vehicle is parked or standing within 12 feet of the road and is giving a warning by appropriate light; returns these violations to infractions punishable by a $250 fine.

Amends GS 20-130.2 to make it unlawful for any vehicle to operate a flashing or strobing amber light while in motion on a street or highway. Sets forth six exceptions, including law enforcement vehicles, emergency response vehicles, vehicles carrying oversize loads, and slow moving vehicles, as specified.
