5.  The governing body of a local government or the Department of Transportation shall designate school zones and school crossing zones. An area must not be designated as a school zone if imposing a speed limit of 15 miles per hour would be unsafe because of higher speed limits in adjoining areas.

6.  Each such governing body and the Department of Transportation shall provide signs to mark the beginning and end of each school zone and school crossing zone which it respectively designates. Each sign marking the beginning of such a zone must include a designation of the hours when the speed limit is in effect or that the speed limit is in effect when children are present.

7.  With respect to each school zone and school crossing zone in a school district, the superintendent of the school district or his or her designee, in conjunction with the Department of Transportation and the governing body of the local government that designated the school zone or school crossing zone and after consulting with the principal of the school and the agency that is responsible for enforcing the speed limit in the zone, shall determine the times when the speed limit is in effect.

8.  If, while violating any provision of subsections 1 to 4, inclusive, the driver of a motor vehicle is the proximate cause of a collision with a pedestrian or a person riding a bicycle, an electric bicycle or an electric scooter, the driver is subject to the additional penalty set forth in subsection 4 of NRS 484B.653.

9.  As used in this section, ‘speed limit beacon’ means a device which is used in conjunction with a sign and equipped with two or more yellow lights that flash alternately to indicate when the speed limit in a school zone or school crossing zone is in effect.
