TOWN OF WYOCENA, Wis. -

A Rio man was injured Tuesday night in a rear-end crash involving a vehicle that had slowed down for a farm tractor on a Columbia County highway, officials said.

Columbia County sheriff’s deputies were called around 6:30 p.m. to Highway 22 just south of Patchin Road on reports of a three-vehicle crash, according to a release.

A farm tractor was going north on Highway 22 and a car had slowed down behind it, but a pickup truck also going north didn’t realize the car had slowed down and ran into the back of the car, officials said.

After hitting the car, the pickup truck swerved and hit the farm tractor, causing it to enter the ditch, according to the release.

The tractor driver, a 30-year-old Rio man, suffered serious but non-life-threatening head injuries and was taken to UW Hospital by Med Flight, officials said. The driver of the car was injured and was taken to Divine Savior Hospital and released.

The pickup truck driver was not injured, according to the release. The pickup truck driver will be cited for inattentive driving, officials said.

Highway 22 was shut down for about two hours, according to the release.

The crash remains under investigation.
