Nevada draws a line most drivers miss: a school zone is 15 mph, but a school crossing zone is 25 mph. They are two different designations, not two versions of the same one, so read the sign rather than assuming. Either limit only applies when the zone is actually active, and Nevada changed how that is decided as of July 2026. There is no longer a blanket half-hour-either-side-of-the-school-day window. The reduced limit does not apply on a day school is not in session, during any period set by the local governing body or the Department of Transportation, when a zone has a speed limit beacon and its yellow lights are not flashing, or when a zone without a beacon carries a sign saying the limit is not in effect. In practice that means the sign and the beacon are the authority, not the clock.
