The driver, Larry Dale Karasch, crashed into the bar at 2 a.m. Saturday, The Portland Oregonian said.
Only a small number of people were still at the Timber Pub & Grub tavern at the time of the accident, and no one was injured.
"The driver did not appear to be injured from the crash, but had several self-inflicted wounds on his arms," a news release states. "The driver was cited and transported to an area hospital, where his wounds would be treated and his mental health will be evaluated."
The Oregonian said it was not immediately clear how much damage the tavern sustained in the crash.
