On Behalf of | Jan 26, 2026 | Drunk Driving |

A first-time DUI or DWI charge can change your life fast. It can affect your freedom, your money and your ability to drive. When you understand how Louisiana law handles these cases, you can better see what may happen next and why early choices matter.

According to Louisiana law, what a first offense involves

According to Louisiana Revised Statutes 14:98 and 14:98.1, a first-time DUI is usually charged as a misdemeanor. You can be convicted if alcohol or drugs impair your ability to drive even when your blood alcohol concentration is below the legal limit.

For most adult drivers, the legal limit is 0.08%. Drivers under 21 face a much lower limit. If you refuse a breath or blood test, the state can impose separate penalties under implied consent laws.

Penalties you may face after a conviction

A first offense brings mandatory penalties that judges must follow. These penalties include criminal punishment and license action:

  • Jail time: 10 days to 6 months, often suspended.
  • Mandatory minimum: 48 hours in jail or 32 hours of community service.
  • Fines: $300 to $1,000 plus court costs.
  • License suspension: One year or two years if BAC is 0.15% or higher.

Judges often add probation, substance abuse evaluations and driver improvement classes. Some cases also require an ignition interlock device. Insurance rates usually increase. When you add all costs together, the total can reach several thousand dollars.

Defenses that may apply in first-time cases

Police actions often shape first-time DUI cases. Many defenses focus on how officers handled the stop and arrest. These defenses include challenging the reason for the traffic stop, questioning test accuracy and pointing out arrest errors.

Officers must give Miranda warnings before custodial questioning. If they fail to do so, the court may block those statements from evidence. These issues can change how strong the case becomes.

Why legal guidance may matter

A first-time DUI involves overlapping criminal and administrative systems, each with strict deadlines and mandatory rules. An attorney can explain how statutes apply to your situation, evaluate possible defenses and help you understand options such as restricted driving privileges. 

When you learn your rights and duties early, you reduce confusion and gain more control over what happens next.
