What is the legal BAC (blood alcohol concentration) limit for drivers over 21 in Mississippi?

In Mississippi, the legal blood alcohol concentration (BAC) limit for drivers who are over 21 years old is 0.08%. This means that a driver can have a maximum of 0.08 grams of alcohol per deciliter of blood before they risk being charged with driving under the influence (DUI). This limit is established to reduce the risks associated with impaired driving, as even small amounts of alcohol can affect a person's ability to operate a vehicle safely. Maintaining a BAC below this threshold helps ensure road safety for all users.

The other options reflect different BAC levels that may correspond to other legal contexts or recommendations in different areas but are not applicable as the legal limit in Mississippi for adult drivers.
