Overview
Alabama treats driving under the influence (DUI) as a serious offense with escalating penalties for repeat offenders. A first-offense DUI is a misdemeanor, but a fourth DUI within a ten-year lookback window becomes a Class C felony carrying up to ten years in prison. Alabama is notable for its mandatory ignition interlock device (IID) requirement even for first offenders who wish to regain restricted driving privileges, and the state imposes some of the longest license suspensions in the Southeast. Alabama also applies an enhanced-penalty tier when a driver's BAC reaches 0.15 or higher.

Felony threshold: 4th DUI offense within 10 years. Lookback period: 10 years — prior DUI convictions within the past 10 years count toward repeat-offender penalties and felony thresholds.
Additional Penalty Details
| Offense | Community Service | Probation | DUI School |
|---|---|---|---|
| 1st Offense | Up to 40 hours at the court's discretion | Up to 2 years; typically 1 year of probation supervision | Mandatory completion of a state-approved DUI or substance abuse education program |
| 2nd Offense | Minimum 30 days of community service | Up to 2 years of supervised probation | Mandatory completion of a state-approved DUI treatment program; court may order inpatient evaluation |
| 3rd Offense | Court-ordered; minimum 60 days of community service | Up to 5 years of supervised probation | Mandatory court-ordered treatment program; inpatient evaluation typically required |
| Felony | Court-ordered; may substitute for portion of jail time | Up to 5 years of supervised probation following release | Mandatory long-term substance abuse treatment program; court may order residential treatment |
Implied Consent Law
Under Alabama Code Section 32-5-192, any person operating a motor vehicle on Alabama roads is deemed to have given consent to a chemical test (breath, blood, or urine) when lawfully arrested for DUI. The arresting officer chooses the type of test administered.
Refusal penalties: Refusal to submit to a chemical test results in an automatic 90-day license suspension for a first refusal. A second refusal within 5 years triggers a 1-year suspension. The refusal can also be used as evidence against the driver in court. There is no separate criminal penalty for refusal alone, but the administrative suspension is immediate.
Aggravating Factors
| Factor | Impact |
|---|---|
| BAC of 0.15% or higher | Triggers enhanced penalties including higher mandatory fines, longer mandatory jail time, and extended IID requirements |
| Child passenger under 14 years old | Charged as a separate offense of child endangerment; adds additional fines and mandatory jail time; may trigger DHS investigation |
| DUI causing bodily injury | Elevated to assault charge (first-degree assault if serious injury); Class B felony with 2-20 years in prison |
| DUI causing death | Charged as criminally negligent homicide or murder; Class A felony with potential 10 years to life in prison |
| Driving on suspended or revoked license (DUI-related) | Additional misdemeanor charge; mandatory jail time and extended license revocation |
| Excessive speed or reckless driving combined with DUI | Additional charges filed; increased jail time and fines; possible felony reckless endangerment charge |
DUI with Injury
Classification: Class B Felony (first-degree assault) or Class C Felony (second-degree assault) depending on severity of injury
First-degree assault (serious physical injury): 2 to 20 years in prison, fines up to $30,000, mandatory license revocation of at least 5 years, and restitution to the victim. Second-degree assault: 1 to 10 years in prison. If the DUI results in death, the driver faces criminally negligent homicide (Class C felony) or reckless murder (Class A felony) with potential life imprisonment.
Underage DUI
Drivers under 21 with a BAC of 0.02% or higher face a 30-day license suspension for a first offense and a 90-day suspension for a second offense. The underage driver must also complete a DUI education course. If the BAC is 0.08% or higher, the underage driver is charged under the standard DUI statute with all standard penalties plus the underage provisions. A conviction stays on the driving record and can affect college admissions, scholarships, and employment opportunities.
Diversion Programs
Program: Pre-Trial Diversion Program (varies by county)
Several Alabama counties offer pre-trial diversion programs for first-time DUI offenders. These programs typically require completion of substance abuse treatment, community service, random drug and alcohol testing, and supervision for 12-18 months. Successful completion results in the DUI charge being dismissed. The programs are administered at the county district attorney's discretion and are not available statewide.
Eligibility: Generally limited to first-time DUI offenders with no prior criminal history, no accident causing injury, BAC below 0.15%, and no aggravating factors such as a minor in the vehicle. Offender must plead guilty or no contest to enter the program. The county DA has final discretion on eligibility.
How Long a DUI Stays on Your Record
A DUI conviction stays on your Alabama driving record permanently — Alabama does not allow expungement of DUI convictions. However, for purposes of calculating repeat-offender penalties, only convictions within the past 10 years are counted. The criminal record can potentially be sealed after a waiting period for misdemeanor DUI offenses under Alabama's 2021 expungement reform, but felony DUI convictions cannot be expunged.
