What is the legal blood alcohol content (BAC) limit for drivers aged 21 and over in Missouri?

In Missouri, the legal blood alcohol content (BAC) limit for drivers who are 21 years old and older is 0.08%. This standard is established to promote road safety by ensuring that drivers are not operating vehicles under the influence of alcohol to a degree that impairs their ability to drive. The 0.08% threshold signifies that drivers with this level of alcohol in their system are considered to have impaired judgment, coordination, and reaction times, increasing the risk of accidents.

This legal limit aligns with many other states, establishing a national standard that supports enforcement and awareness regarding DUI laws. The other options represent levels of BAC that are either below the legal limit, which may still require caution but do not automatically result in penalties, or above the limit, which would lead to legal consequences.
