House committee substitute makes the following changes to 1st edition. Amends proposed GS 20-118(1) to direct the Secretary of Transportation to adopt rules governing payment arrangements for civil fines for overweight vehicles, and to post the rules on the Department of Transportation's (DOT) website. Requires the citations issued for these violations to advise the driver to consult the DOT website or to contact the DOT to find out if the state will agree to a payment arrangement and, if so, on what terms. Previous edition authorized certain persons to make a payment arrangement of $250 or more for any penalty assessed. Effective January 1, 2012, and applies to violations occurring on or after that date (was, effective when the act becomes law). Makes conforming changes to the bill title.
