What is Legal Limit Bac?
Category: Legal
1Definition
The maximum blood alcohol concentration at which someone can legally operate a vehicle—0.08% in most U.S. states.
2Context
Exceeding this limit is DUI regardless of impairment. Commercial drivers and minors have lower limits.
3Example
A 180-pound man reaches 0.08% BAC after about four drinks in two hours—the legal limit for driving.
⚠Common Trap
Being under the legal limit doesn't mean you're safe to drive—impairment begins well before 0.08%.
