N.J. Stat. § 39:4-183.1a
Notwithstanding any law to the contrary, a municipality may, upon the request of the appropriate board of education or, in the case of a private school, by the school's governing body, provide by resolution for the installation of a traffic control device or sign consistent with the current standards prescribed by the Manual of Uniform Traffic Control Devices for Streets and Highways as adopted by the Commissioner of Transportation, to regulate motor vehicle traffic at an intersection located within 300 feet of any public or private school; provided that the municipal or county engineer shall, under the engineer's seal as a licensed professional engineer, certify to the municipal or county governing body, as appropriate, that the traffic control or device has been approved by the engineer after the engineer's investigation of the circumstances. Before a resolution shall take effect, however, the governing body shall submit a copy of the resolution to the Commissioner of Transportation for his review and approval together with detailed information as to the location of streets, intersections and signs affected by any installation, traffic count, accident and speed sampling data when appropriate, the municipal or county engineer's certification, under the engineer's seal as a licensed professional engineer, to the municipal or county governing body, and any other information as the commissioner may require. If the commissioner disapproves the resolution, he shall file his disapproval, in writing, with a statement of the reasons for his disapproval, with the governing body within 90 days following the receipt of the resolution. If the commissioner approves the resolution or fails to file his disapproval within the 90-day review period, the resolution shall take effect immediately.
For the purposes of this section, the term "public or private school" has the meaning that term is given in N.J.S. 18A:1-1.
