Safe & Responsible DrivingStandalone practice
For a driver 21 or older in an ordinary passenger car, at what blood alcohol content (BAC) does driving become an offense in Missouri, even without other signs of impairment?
Correct answer: 0.08% or more
Why
The 0.08% limit is a per se rule: the test result alone is enough for the offense. You can still be charged with driving while intoxicated at a lower BAC if alcohol or drugs impair you, and even one drink can affect your driving. The only safe plan is not to drive after drinking.
