Senate amendment to the 4th edition makes the following changes.
Section 17.5.
Recodifies the provisions GS 20-141 authorizing the City of Durham to set a municipal default speed limit from GS 20-141(f1) to GS 20-141(e2). Reduces the minimum speed limit from 25 to 20 miles per hour and now exempts the State highway system from the municipal limit (was, authorize a speed limit of 25 miles per hour on all municipal streets and State highway system streets, except those designated as part of the Interstate Highway System or other controlled-access highway, as described). Now allows the speed limit to be effective without requiring the posting of individual speed limit signs on each street segment, provided the municipality erects conspicuous gateway signs at each primary point of vehicular entry into the municipality or into any defined zone within the municipality, as specified (was, signs need to be erected at the boundaries of the designated areas). Specifies that the speed limit is effective upon passage of an ordinance and the posting of the required gateway signs. Provides for a publicly accessible map of all streets subject to the default speed limit and those with a different speed limit. Provides for posting of the applicable statutory speed limit by the Department of Transportation (DOT) upon written notice by the municipality.  
Section 17.6.
Applicable only to the City of Durham, requires DOT to complete an initial review of a request (a written submission seeking the establishment or modification of a speed limit on a street located within the corporate limits of the municipality that is part of the State highway system, as specified) within 30 days of the date of receipt of the request and either (1) approve the request or (2) issue a written notice of concern raising the matters specified. Specifies that issuance of a notice of concern constitutes final DOT action, unless the municipality submits a revised or supplemented request or files an appeal. Deems the request approved if DOT fails to take action within 90 days of receipt of a request or within 90 days of a revised or supplemented request. Directs that upon approval of a request, DOT will execute a concurring ordinance within 60 days and erect appropriate speed limit signs on the affected State highway system streets within 60 days thereafter. Specifies that the speed limit is effective when DOT has erected the signs. Clarifies that the act does not authorize a municipality to unilaterally establish or modify speed limits on streets that are part of the State highway system, or to require DOT to approve a speed limit that is not reasonable and safe under the conditions found to exist upon the affected highway.
Section 25.
Replaces reference to “enterprise pursuant to Chapter 160A” with “enterprise” in GS 136-18(10). Removes provisions explaining how a compensable property interest may be demonstrated by an easement or by an affidavit executed by the electric membership corporation or municipally owned electric enterprise as described. Defines municipally owned electric enterprise to mean an enterprise owned or operated pursuant to GS Chapter 160A or an enterprise owned or operated by a public works authority or public utilities commission created pursuant to a local act of the General Assembly.
Section 32.5
If Senate Bill 595, 2025 Regular Session, becomes law, then directs that the definition of retailer in GS 105-187.l(a)(6), as amended by Section 7.l(a) of that act, is expanded to include persons in the business of selling motor vehicles and makes technical changes. Effective October 1, 2026.
