How Much Can I Drink Before I am Legally Drunk?

Criminal DUI charges only apply if your blood alcohol content (BAC) exceeds the legal limit. Those limits are the same in Wyoming and South Dakota:

  • Most drivers: .08%.
  • Minors under 21 years old: .02%.
  • Commercial drivers: .04%.

How many drinks it takes to hit those limits depends on several factors, including:

  • Gender
  • Body weight
  • Prescription medications
  • Type of drink
  • Alcohol by volume in the drink
  • Speed of consumption
