A spokesman for the American Bus Association said buses carry more than 700 million passengers a year in the United States.
"The industry as a whole is a very safe industry," said Dan Ronan of the Washington, D.C.,-based group. "There are only a handful of accidents every year. Comparatively speaking, we're the safest form of surface transportation."
The bus crash comes more than two months after another chartered tour bus in October veered off a highway in northern Arizona, killing the driver and injuring dozens of passengers who were mostly tourists from Asia and Europe. Authorities say the driver likely had a medical episode.
The bus crash was the second fatal accident on I-84 Sunday morning amid slick, icy conditions. A 69-year-old Post Falls, Idaho man, Freeman Glenn Thomason, died when the pickup in which he was a passenger left the road and overturned east of Stanfield.
La Pine resident Melissa Marcotte was among those returning from a wrestling tournament in La Grande and was stuck behind the crash scene for about two hours. She said they got off the highway onto a detour on an access road above the crash scene, and shared a photo.
"Sure makes the next five hours home a very sad, anxious drive," Marcotte said.
The crash occurred on a stretch of I-84 that others commenting on NewsChannel 21's Facebook page said is often very treacherous to drive during the winter.
