In Nevada, a child under what age must be secured in a rear-facing child restraint system in the back seat?

The rear-facing requirement runs through the second birthday, not the first. Older national guidance capped rear-facing seating at the first birthday, and that outdated rule of thumb still gets picked. This answer recalls the older age-one rear-facing guideline instead of Nevada's current age-two threshold.

Age four is not Nevada's rear-facing threshold; the rear-facing back-seat requirement applies to children under two. This answer splits the difference between Nevada's under-two rear-facing rule and its under-six general child-restraint rule to guess a midpoint.

Age six appears in Nevada's general child-restraint rule, but the rear-facing back-seat rule applies only to children under age two. The broader under-six restraint rule gets remembered as the rear-facing rule. This answer reaches for the more visible under-six restraint figure that headlines the Buckle Up section, not the separate infant provision buried below it.
