What is the legal BAC for a driver?

0.08%
0.15%
0.05%
0.18%

The correct answer is: 0.08%

The legal BAC (blood alcohol concentration) for a driver is 0.08%, which means that for every 1000 milliliters of blood, there are 8 milliliters of alcohol. This is considered the legal limit in most states in the United States. It is important to note that this refers to the BAC level for adult drivers over the age of 21. 0.15% (B) and 0.18% (D) are both higher than the legal limit and would result in charges for driving under the influence (DUI) or driving while intoxicated (DWI). 0.05% (C) is below the legal limit, but it is still considered a "per se" DUI in some states, meaning that a person can still be charged with a DUI even if their BAC is below 0.08% if other evidence
