The recent fatal school bus crash in Chattanooga has school districts across the nation assessing the safety of their own school buses, drivers and school transportation programs. WLOS ABC News Channel 13 recently reported on some efforts going on in Canton. In North Carolina, school buses have to be checked by a licensed inspector every 30 days. Additionally, school buses in North Carolina are not to exceed speeds of 45 miles per hour. Some districts are adding cameras on the inside and outside of buses to help improve accountability in the event of a wreck or other potentially injury-causing incident. Although these measures certainly help to improve school bus safety, taking the bus to and from school isn't totally without risk.
