Wayne Hansen says he doesn't remember much about the day he was pulled over for driving under the influence.
"I grabbed the wrong bottle, and that's the last thing I remember doing," said Wayne.
A similar situation for Lindy Patnode. Like Wayne, she had taken the sleep aid Ambien before getting behind the wheel.
"I had taken it the night before as prescribed and was headed to work at 9:30 in the morning, and I was stopped," said Lindy.
Both people were charged with driving under the influence.
"It was an absolute mistake," said Wayne. "I would never intentionally do what I did. That goes against my entire being."
Police say that simple mistake caused Wayne to drive into oncoming traffic, drive onto the sidewalk and almost hit a bus. Wayne hadn't been drinking or taking any street drugs at the time.
"The danger presented to the community is the same," said Assistant City Prosecutor Andrew Reinen.
Lindy doesn't believe she should be charged with a DUI. She says she took the drug as prescribed and didn't hurt anyone.
But the trooper and officer involved in her arrest cited the danger. They say Lindy was swerving all over the road before she was caught.
"It felt a little weird at that intersection, I admit that, but I didn't hit anything, I didn't hurt anybody," said Lindy.
The city prosecutor isn't taking any chances in going after cases of people who cause a threat - no matter the drug.
"Ambien can be different. It's not the same as going to the bar and getting drunk, so, while we don't necessarily view it as unethical, it still possesses the same risks to the community," said Reinen.
Wayne intends to appeal his DUI conviction. Lindy will be back in court for her trial Friday.
