Decoding Alabama DUI Jail Time and Mandatory Sentences

A conviction for Driving Under the Influence (DUI) in Alabama triggers severe consequences, including fines, driver’s license suspension, and mandatory substance abuse programs. For many, the most pressing concern is the prospect of incarceration. The potential jail or prison time is determined almost entirely by the number of prior DUI convictions on your record within a specified look-back period of ten years.

The severity of sentencing increases significantly with each subsequent offense, shifting from a misdemeanor with discretionary jail time to a Class C felony punishable by state prison.

First-Time DUI Offense: Misdemeanor Sentencing

A first conviction for DUI is classified as a misdemeanor. While there is no mandatory minimum jail time for a standard first offense, a convicted person faces potential imprisonment.

• Maximum Jail Time: Up to one year (365 days) in a county or municipal jail.
• Fine Range: Not less than $600 and not more than $2,100.
• Alternative Sentencing: Judges have wide discretion and may opt to sentence a first-time offender to probation, community service, and mandatory DUI education programs instead of jail time.
• License Suspension: 90 days, which can often be stayed or mitigated by the installation of an Ignition Interlock Device (IID).

Second and Third Offenses: Mandatory Minimum Incarceration

Repeat DUI convictions within the ten-year look-back period carry mandatory jail sentences that cannot be suspended or probated. This is a critical distinction that significantly increases the stakes in a DUI trial.

Second DUI Offense (Within 10 Years)

For a second DUI conviction, the state imposes an immediate, non-negotiable sentence to ensure time is served.

• Mandatory Minimum: Five days of imprisonment, which cannot be suspended or probated. This may sometimes be satisfied by 30 days of community service.
• Maximum Jail Time: Up to one year.
• Fine Range: $1,100 to $5,100.

Third DUI Offense (Within 10 Years)

A third offense dramatically increases the mandatory minimum sentence a person must serve.

• Mandatory Minimum: 60 days of continuous imprisonment in a county or municipal jail, which cannot be suspended or probated.
• Maximum Jail Time: Up to one year.
• Fine Range: $2,100 to $10,100.

Fourth or Subsequent Offense: Felony DUI and State Prison

In Alabama, a fourth or subsequent DUI conviction within a ten-year period is elevated to a Class C felony. Felony charges result in a sentence to state prison rather than a county jail and are associated with the most severe penalties.

• Felony Classification: Class C Felony.
• Prison Time Range: Not less than one year and one day and up to 10 years in state prison.
• Mandatory Minimum to Serve: The sentence includes a mandatory minimum of 10 consecutive days in the county jail, served as part of the total sentence.
• Fine Range: $4,100 to $10,100.
• License Revocation: Five years.

Third Offense (Misdemeanor)	Up to 1 Year (365 Days)	60 Days
Fourth or Subsequent Offense (Class C Felony)	1 Year and 1 Day up to 10 Years in State Prison	1 Year and 1 Day (with a minimum of 10 days in county jail to serve)

Key Takeaways on Alabama DUI Sentencing

1. While a judge has discretion to suspend or probate a jail sentence for a first-time DUI, subsequent offenses carry specific, non-suspendable mandatory minimum jail sentences that must be served.
2. The penalties are primarily determined by the number of prior DUI convictions within the preceding ten-year period.
3. A fourth or subsequent DUI conviction is automatically charged as a Class C felony, moving sentencing from a county jail to state prison with a maximum of 10 years.
4. Aggravating factors, such as a high BAC (0.15% or higher) or the presence of a minor in the vehicle, can increase the severity of the sentence and the likelihood of jail time, even for a first offense.
5. In many cases, a person convicted of DUI must install an Ignition Interlock Device (IID) for a set period, which can sometimes be elected to stay a license suspension.
