WOODBURN, Ore. -- A band saw that fell off a trailer on southbound Interstate 5 Tuesday evening was hit by 10 vehicles, including a van that rolled several times, according to Oregon State Police.

About 9:30 p.m., dispatchers received a call about a large object on the freeway about two miles north of Woodburn. Within a minute, more calls came in of drivers striking the object.

The object was a red and black band saw about five feet long and two feet high. It fell off a trailer being towed by larger "personal style" pickup truck like a Ford F-250, police said.

Most of the vehicles that hit the saw had minor damage. Their occupants were not injured. The injured driver of the van was taken to a hospital.

The driver of the pickup stopped and ran toward the saw. He then ran back to the truck and drove away. There is no further description of him, police said.
