A Walkerton man passed out behind the wheel before he could get to the toll booth on the Indiana Toll Road.

Indiana State Police say the vehicle parked at the toll booth Thursday morning at the Notre Dame exit was still running when officers arrived. Officers also noticed one of the vehicle’s tires was flat and missing.

The driver reportedly showed signs of impairment and would even pass out as a trooper talked to him, according to Indiana State Police.

The driver was arrested and initially charged with OWI and possession of a controlled substance. He was also reportedly found with several pills believed to be Klonopin.

He was taken to St. Joseph County Jail. He was not identified by officers because charges are still pending.
