Parts of Interstate 43 were closed for about two hours while authorities cleaned up beef byproducts such as intestines and bones, said Sgt. Blaine Spicer of the Sheboygan County Sheriff's Department.
The accident happened in the Town of Mosel around 2:15 a.m. when 25-year-old Ryan Engle's truck veered off the road as he adjusted his MP3 player, Spicer said.
Engle, of Kenosha, was cited for inattentive driving, and taken to a hospital with non-life threatening injuries, Spicer said.
The semi had to be towed from the scene. It is owned by Birchwood Transport, of Kenosha.
