Some 30 tour bus passengers are undergoing treatment at area hospitals this morning after the bus rolled over on US Highway 36 near Broomfield and Westminster.
The accident happened just before nine a-m on a road commonly called the Boulder Turnpike, and involved at least two other vehicles including a UPS delivery truck.
Westminster police Investigator Tim Read says none of the injuries appear to be critical, but children aboard the Coach USA bus were among those who were hurt.
The bus is owned by Powder River Transportation Company of Gillette, Wyoming, where officials declined comment.
A call to Dallas-based parent company Coach USA has not yet been returned.
