Ryan Dickson hoped to leave Trans Iowa with a new job Monday morning. Instead, Dickson left in handcuffs.

The Des Moines man allegedly drove himself drunk to a job interview for a position as a taxi cab driver.

"I just get out there and a little white car comes pulling in and smashes into one of our driver’s cars,” said Trans Iowa Dispatcher Barbara Freeborn.

Freeborn said she witnessed the perspective co-worker damage two cars in the parking lot, then stammer inside the building.

"I go in and he’s standing there and I’m like, ‘Sir, have you been helped?’ and he couldn’t comprehend what I was saying,” said Freeborn.

Police say Dickson was unable to finish a field sobriety test because he was too intoxicated. A preliminary breath test showed he blew a .273 -- more than three times the legal limit – all before 9:30 a.m.

"With the blood alcohol content that he had, he’s definitely a danger at that moment,” said Des Moines Police Sgt. Paul Parizek. “So we’re glad that we were able to get up there and get this guy in custody at that time.”

A police report indicates Dickson drank until around 2 in the morning, checked himself into the hospital for alcohol consumption and then began to drink again upon his release at 8 a.m.

Dickson drank a fifth of vodka prior to the interview.

He is charged with operating while intoxicated - first offense.

Trans Iowa said it is thankful an alert employee noticed the erratic driving as the applicant pulled into the parking lot and alerted authorities.

Police are reviewing surveillance video for their investigation.
