Penultimate Amazing
It's the totality of the circumstances. The driving behavior. The behavior during the investigation. A strong odor of alcohol or marijuana coming from the car or the driver. Glassy or bloodshoot eyes. Slurred or slow speech. Delayed response. Failure to maintain a coherent train of thought. Confusion over simple instructions. Inability to keep track of complex instructions. Lack of physical coordination. Excessive involuntary nystagmus. All these things make up a large part of the investigating officer's evaluation, before the breathalyzer even comes into play.The problem of course with that is the subjectivity that gives police. Where they arrest people for DUI after blowing 0 on the breathalyzer.
A number of these observations are made via standardized tests that are taught the same and administered the same across the country. City cops, county sheriffs, state troopers all administer the exact same tests in the exact same way. And this is identical to the way these tests were administered to me thirty years ago. Especially nowadays, with bodycams, the subjectivity isn't really as big a problem as you think.
A lot of people don't understand that a seemingly simple test like the Walk and Turn is also about your ability to stand still, listen to a series of instructions, and keep the entire series in mind as you go through each one.
"Stand with your hands at your side, right foot in front of left, heel to toe, like this."
[Driver struggles to get it right.]
"Okay, now I want you to stay in this position until I tell you to begin."
[Driver wobbles, steps out of position, has to be reminded to get back in the starting postion.]
"When I tell you to begin, I want you to take nine heel to toe steps-"
[Driver starts attempting heel to toe steps, has to be reminded to stay in the starting position until told to begin.]
"When I tell you to begin, I want you to take nine heel to toe steps. I'm going to demonstrate three, I want you to do nine, okay?"
[Driver is out of the starting position again.]
The script is always the same. The test protocol is always the same. There's nothing subjective about these observations. This driver is already going to jail on a DUI charge even if they refuse to do any more tests, and even if they refuse to give a breath sample.
