An incoherent police chief in Utah lost his balance during a field sobriety test before he was arrested for DUI, video shows.

Mantua Police Chief Shane Zilles was spotted by a state trooper on Jan. 29 traveling at least 86 mph in the center median of Route 91 near Sardine Canyon, barreling down the highway without turning on his emergency lights or sirens, according to a Utah Highway Patrol report obtained by Deseret News.

“I’ll be honest, you’re really worrying me by how you’re acting right now,” the trooper told Zilles, according to redacted dashcam video released Thursday by the state’s Department of Safety. “Are you on any meds?”

Zilles then gives an unintelligible response to the trooper before being told that if he’s headed to work — as Zilles indicated — he’s traveling in the wrong direction.

“If you’re headed to the office, you’re going the wrong way,” the trooper said.

“Oh, oh,” Zilles replied. “All right, well.”

The trooper also let Zilles know that he had already been to work that day. At another point, the chief told responding troopers that it was Sunday or Monday when it was actually Tuesday, according to the Salt Lake Tribune.

The dashcam video then shifts to Zilles performing field sobriety tests, including one in which he’s seen losing his balance while trying to stand on one leg. Zilles nearly falls to his left at one point, video shows, as he struggles to maintain his balance while seemingly scoffing at his predicament.

A blood alcohol test then detects no booze on Zilles’ breath before the police chief told the trooper that he last took his medication several hours earlier, video shows.

“Shane, I hate to do this, OK?” the trooper continues. “This is an awkward position for me to be in, but I don’t think you’re safe to be driving. And unfortunately, I don’t have much of a choice. Let me have you put your hands behind your back here.”

Zilles was later charged with misdemeanor counts of DUI and reckless driving on Feb. 8. The mayor of Mantua — a small town of roughly 700 residents north of Salt Lake City — later announced that Zilles had been fired following his arrest.

“We also hope that Mr. Zilles can work his way through this tough time and find a better path in the future,” Mayor Michael Johnson said in a statement obtained by the Salt Lake Tribune. “It appears that prescription meds have claimed another good person’s reputation.”
