New Jersey Statutes Title 39. Motor Vehicles and Traffic Regulation 39 § 4-191.1

a. Markings shall be placed only by the authority of a public body or official having jurisdiction as authorized by law, and only for the purpose of regulating, warning, or guiding traffic. Where used, these markings shall be uniform in design, position, and application. The Commissioner of Transportation may adopt a uniform system of markings consistent with the provisions of this act for use upon public highways within the State. Such a uniform system of markings shall correlate with and so far as possible conform to the current “Manual on Uniform Traffic Control Devices for Streets and Highways.”

b. No markings made from paint that has been mixed, in whole or in part, with reflective glass beads containing more than 100 parts per million inorganic arsenic, as determined by x-ray fluorescence, shall be placed on or along any State highway, right-of-way, or other real property owned by or under the administration, jurisdiction, or control of the Department of Transportation.
