Short for blood alcohol content, BAC is a measure of the concentration of alcohol in your bloodstream. When your BAC reaches a certain threshold, it becomes illegal to operate a motor vehicle. In Indiana, that threshold is 0.08% or higher.
Despite this simplistic answer, there is a lot to remember about BAC, including situations where you can still be arrested for a DUI even if your BAC is zero. If you or a loved one has been charged with a DUI, contact Mark Worthley of Worthley Law. As a DUI lawyer in Valparaiso, he offers free, no-obligation consultations.
All 50 states (Utah excepted) cap the blood alcohol concentration at 0.08%. A BAC that meets or exceeds that number is considered too impaired to drive safely and legally.
Drivers who far exceed a 0.08% BAC may be subjected to harsher penalties, including jail time, due to the causal connection between very high BACs and the instances of fatal accidents. These stricter penalties are meant to serve as a deterrent, prompting drivers to limit their drinking or find safer, alternative means of transportation, such as a ridesharing service. The inconvenience and expense of finding alternative transport while impaired is preferable to paying hefty fines and spending days in jail.
Even though the legal limit for blood alcohol content in Indiana is 0.08%, you could still be arrested for a DUI even if you are below this limit.
The following circumstances trigger a zero-tolerance policy when an officer observes that a driver is “noticeably impaired”:
Theoretically, under this policy, you could have a BAC of 0.0% and still be arrested on suspicion of a DUI.
A fraction of a percent of alcohol in the bloodstream might seem insignificant, but it helps to put things into perspective.
Alcohol interferes with how the brain communicates with the nervous system, acting as a depressant. In plain English, it slows down the brain. Even small amounts of the liquid can affect speech, movement, reflexes, memory, and even judgment.
Though every person metabolizes alcohol differently, on average, here’s what you can expect at various BAC levels:
Every person is unique, and we all process alcohol differently. While one person can become noticeably impaired after a single drink, another person may be able to stomach more alcohol before their BAC levels rise to illegal limits.
There are several factors that influence BAC levels, including:
On average, one can metabolize one drink per hour, but there are other variables to consider, including the list above.
There are commercially available breath tests available that can give you an idea of what your BAC level is. As a general rule, it’s recommended to abstain from driving, even if you’ve only had one drink. Often, drunk drivers get into trouble when they try to estimate whether they are “drunk” based on various self-assessments.
It can be tempting to tell an officer that you do not consent to a BAC test in hopes of preventing the police from gathering evidence that can be used against you.
Indiana, however, follows an “implied consent” standard, which means that by obtaining a driver’s license, you consent to have your blood alcohol content (or any other substance concentration) tested as long as an officer has probable cause. Therefore, if you have a driver’s license in Indiana, you have given consent for a BAC test.
If you refuse a BAC test, you may be subject to having your driving privilege revoked for one year. That timeframe extends to two years if you have a prior DUI conviction.
