Southwestern High School junior Crystal Sneed, left, and eighth-grader Victoria Palmer help kindergartner Michael Sommer exit the rear emergency door of bus driver Donna Brooks' bus during an evacuation drill on Tuesday. The evacuation drills, which will continue through Friday, are part of Bus Safety Week, a national program that Southwestern participates in each year. The week also includes school bus safety training for students at the elementary school with a video and hands-on learning about the proper distance to walk around a bus, how to properly cross the street at a bus stop and more.
