BAC Limits in Louisiana
The legal BAC limit for drivers 21 and over is 0.08%. For commercial vehicle operators, it is 0.04%, and for drivers under 21, it is 0.02%. You can still be arrested for DWI if your driving is impaired, even if your BAC is below these limits.
Louisiana has an “implied consent” law, meaning that by driving, you agree to a chemical test if arrested for DWI. Refusing this test results in an immediate license suspension for at least one year, separate from any criminal penalties.
