What is the legal blood alcohol concentration (BAC) limit for adult drivers?

The legal blood alcohol concentration (BAC) limit for adult drivers in Missouri is 0.08%. This standard is established to promote road safety and reduce incidents of impaired driving. At this level, drivers are presumed to be impaired, which means they may face legal consequences if caught driving under the influence. This limit is consistent with the national standard across many states, making it widely recognized.

Different BAC thresholds exist for other categories of drivers, such as commercial drivers or those under the legal drinking age, where the limits are lower or even set at zero. Understanding this limit is crucial for any driver as it affects the legality of operating a vehicle after consuming alcohol.
