Last April, a deadly bus accident occurred in Northern California when a Federal Express delivery truck driver traveling south inexplicably swerved across Interstate 5 into the northbound lanes and crashed into a charter bus carrying high school students from the Los Angeles area. The accident happened around 5:40 p.m. when the truck, which was hauling two 28-foot trailers drove across the median of Interstate 5 near Orland. There was no fence or wall to prevent traffic from entering the oncoming lanes. The truck initially hit the back of a passenger vehicle and then hit the front of the bus carrying the high school students. The students were on their way to Humboldt State University in Arcata to attend weekend orientation program. Upon impact, the truck and the bus caught fire. Both the driver of the truck and the driver of the bus were killed, as well as five students and three of their adult chaperones.
