First Offense Penalties in Louisiana
Implied Consent & Test Refusal
Like all 50 states, Louisiana has an implied consent law — by driving on Louisiana roads, you've already agreed to submit to a chemical test (breath, blood, or urine) if an officer has probable cause to believe you're impaired.
Refusal Penalty
180-day license suspension (for first refusal, doubled if under 21)
Louisiana-Specific Detail
Louisiana allows first-offense DUI charges to be eligible for diversion or expungement in some jurisdictions. The state's legal drinking culture makes DUI enforcement practices vary significantly between parishes.
