For which grade levels is a hand-held stop sign required when escorting students across the street?

A hand-held stop sign is required when escorting students across the street at all grade levels to ensure the safety of every child, regardless of their age. The purpose of the stop sign is to provide a clear visual cue to drivers that they must stop while children are crossing, contributing to a safer environment for students. All children, whether they are in pre-kindergarten or eighth grade, are vulnerable when it comes to traffic situations, and using a stop sign helps reinforce a consistent safety protocol. This practice aligns with the goal of protecting all students and ensuring their safe passage, making it essential across all grade levels.
