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

In Louisiana, the legal blood alcohol concentration (BAC) limit for drivers over 21 years old is set at 0.08%. This threshold is established to help ensure that drivers remain sober and capable of operating a vehicle safely. Driving with a BAC of 0.08% or higher is considered driving under the influence (DUI), which can lead to various legal penalties, including fines and license suspension. Setting this limit reflects research indicating that impairment begins at lower levels of alcohol, but 0.08% serves as the universal legal standard for intoxication in many states, including Louisiana. Understanding this limit is essential for promoting safe driving practices and encouraging responsible alcohol consumption among drivers.
