What is the illegal blood alcohol concentration level for an adult driving a vehicle?

In Missouri, the legal blood alcohol concentration (BAC) limit for an adult operating a vehicle is set at .08% or more. This means that individuals who are found to have a BAC at or above this level while driving can be charged with DUI (driving under the influence).

The .08% threshold is based on extensive research that shows impairment begins to affect driving ability even at this level. It serves as a standard legal limit, recognized not only in Missouri but in many states across the country, which ensures consistency in enforcement and helps to promote safer roadways.

Lower BAC levels, such as .05% or .10%, may also represent concerning impairment; however, they do not constitute the legal threshold for DUI charges in this state. Understanding the significance of .08% helps ensure that drivers are aware of the risks and legal consequences associated with drinking and driving.
