A semitrailer truck rolled over and spilled 25,000 pounds of milk early Wednesday, and the driver was arrested on his fourth intoxicated-driving charge, Rock County sheriff’s officials said.

Deputies responded at 2:41 a.m. Wednesday to report of a semi in the south ditch near 8823 E. Highway 67, according to a news release.

The semi was lying on its passenger side in the ditch. The driver, Mark Noble, 49, of Walworth, was still in the cab and unable to get out, according to the release.

Noble had been traveling east on Highway 67 when he drove into the ditch, according to the release. The trailer had been carrying 50,000 pounds of milk, half of which spilled into the ditch.

Deputies helped Noble out of the cab, and he was treated for injuries. Deputies said they noticed Noble showed signs of impairment, so they conducted a field sobriety test. Noble later admitted drinking alcohol before the crash, according to the release.

Noble was arrested on a charge of fourth-offense intoxicated driving.

He is currently being held at the Rock County Jail.
