Annual Inspection Guide - School Transportation Technician 

The Colorado Department of Education (CDE) School Transportation Unit has promulgated this resource guide to assist public school districts as well as Boards of Cooperative Educational Services (BOCES) with developing policies and procedures for the safe transportation of students. These guidelines provide manufacturer recommendations, industry standards and best practices which are consistent with the Colorado Minimum Standards Governing School Transportation Vehicles, 1 CCR 301-25 and the Colorado Rules for the Operation, Maintenance and Inspection of School Transportation Vehicles 1 CCR 301-26. This publication is intended to serve as a transportation provider resource toward compliance with legislation and regulations. Link to Guide.
