You’ve heard of DUI. Maybe even OWI. But if you’ve been charged in Indiana, chances are you’re dealing with something called an OVWI. It stands for Operating a Vehicle While Intoxicated, and it covers everything from weaving in your lane to full-blown crashes. Whether it’s your first offense or your fourth, we’ve got answers to the questions people ask us all the time.
Spoiler alert: There’s no meaningful difference.
Indiana focuses on the word operating because you don’t actually have to be driving to get arrested. If you’re behind the wheel, engine running, keys in the ignition—or even just parked in a drive-thru line—that’s operating, and that’s all it takes. The law here casts a wide net, and you’d be surprised how many people get caught up in it without ever hitting the gas.
Let’s not sugarcoat it: the penalties can go from annoying to absolutely life-altering.
This isn’t Monopoly—you don’t just pass Go and pay a fine. The consequences are real, and they don’t end when the court case is over.
Here’s the deal: if you drive in Indiana, you’ve already agreed to chemical testing if the police think you’re intoxicated. That’s what “implied consent” means.
When cops stop you and say they have probable cause, they’re going to ask, Do you now consent to a chemical test? The only good answer is yes.
Why? Because if you say no:
So you’ve just added a second suspension for refusing—and they still got the evidence they were after. It’s the legal equivalent of tripping over your own shoelaces and face-planting in court.
You’ve seen them on TV—walking in a straight line, balancing on one leg, following a pen with your eyes. Here’s the breakdown:
These aren’t just balance tests—they’re tests to see if you follow instructions under pressure. But guess what? They’re far from perfect. Old injuries, anxiety, being overweight, or wearing the wrong shoes can throw off your performance.
There are also non-standardized tests—like counting backwards or reciting the alphabet out of order. These don’t carry the same legal weight, but cops might still use them as “evidence” of impairment.
BAC = Blood Alcohol Concentration
ACE = Alcohol Concentration Equivalent
Both are ways of measuring how much booze is in your system. It can be tested via:
Here’s the math:
Important note: 0.15% does not mean 15% of your blood is alcohol. That would probably kill you. It means 0.15% of your blood volume contains alcohol—enough to impair your judgment, reaction time, and coordination.
It depends on a few key things:
Bottom line? We’ll fight to keep you behind the wheel if the law allows it. Just know there are some battles we can’t win—because the law won’t let us.
