Alabama DUI Penalties: Fines, Jail Time, and Probation by Offense

How Long Is a DUI Sentence in Alabama?

DUI jail time in Alabama ranges from no mandatory minimum on a first offense to ten years in state prison for a fourth or subsequent conviction. Under Alabama law, a first-offense DUI carries up to one year in county jail. A second offense within ten years requires a mandatory five days in jail – or at least 30 days of community service. A third offense demands a mandatory 60 days that cannot be suspended. A fourth or subsequent DUI is a Class C felony with prison time of one year and one day to ten years.

This page breaks down Alabama penalties for a DUI, offense by offense. We cover fines, jail time, probation, and license consequences. Knowing these penalties helps you see what a conviction means. The DUI minimum sentence depends on three things. Those are the offense number, any aggravating factors, and the judge's choice within the statutory range. Every number below comes straight from Alabama law on DUI penalties. Charts and ranges cannot replace a close look at your own case. Talk with an Alabama DUI defense attorney about your situation.

All convicted Alabama DUI offenders must complete a DUI or substance abuse court referral program.

Alabama law applies to a person who drives or is in actual physical control of a vehicle. For a driver 21 or older, the legal limit is 0.08 percent by weight of alcohol in the blood. Alabama law also sets lower limits for some drivers. Those are 0.02 percent for a driver under 21 or a school bus or day care driver on duty, and 0.04 percent in a commercial vehicle. A driver can also be convicted of driving under the influence of alcohol, which does not depend on a blood alcohol level reading.

First-Offense DUI Penalties in Alabama: Jail Time, Fines, and Probation

A first DUI conviction in Alabama is a misdemeanor. Under Alabama law, the court may impose up to one year in county or municipal jail. No statutory mandatory minimum jail term exists for a standard first-offense DUI. So the judge decides whether to order any jail time at all.

Jail Time for a First Offense

The maximum is one year in the county or municipal jail. Many first-offense cases end in probation rather than jail time. Still, the judge can order the full year. A high BAC or poor behavior at arrest may lead to a harsher sentence.

Fines for a First Offense

The fine range is not less than $600 and not more than $2,100 under Alabama law. The court sets the amount within that range. Court costs and fees apply on top of the base fine.

Substance Abuse Treatment

Every person convicted of a first-offense DUI in Alabama must complete a DUI or substance abuse court referral program. The court will order an evaluation. The counselor then decides whether you need more treatment.

Probation for a First Offense

First-offense DUI probation may last up to two years. Common conditions include finishing the court referral program and staying off alcohol and controlled substances. Courts also order random testing and payment of all fines and court costs. The judge may grant probation instead of active jail time.

License Suspension and Ignition Interlock

A first conviction triggers a 90-day license suspension. The suspension may be stayed if the offender installs an approved ignition interlock device for 90 days. Aggravating factors extend the mandatory interlock period to one year. These factors include a BAC of 0.15 or higher and a child under 14 in the vehicle. They also include injury to another person or refusal to submit to a chemical test.

Second-Offense DUI Penalties in Alabama (Within 10 Years)

A second DUI conviction within ten years is still a misdemeanor. But it carries much steeper consequences. Under Alabama law, a second DUI carries a mandatory sentence that cannot be suspended or probated.

Jail Time for a Second Offense

The sentencing range is not less than five days and not more than one year in the county or municipal jail. The sentence includes a mandatory minimum of five days in jail, which is not subject to suspension or probation. As an alternative, the judge may allow the offender to perform at least 30 days of community service instead of the five mandatory jail days.

Fines for a Second Offense

The fine range is not less than $1,100 and not more than $5,100 under Alabama law. The court sets the amount within that range.

License Revocation and Interlock After a Second Offense

The Alabama State Law Enforcement Agency will revoke the offender's license for one year. After a minimum of 45 days of the revocation period, a court order and proof of installation start the required two-year interlock period. Completing the two-year interlock period commutes the remaining revocation. Alabama also suspends the vehicle registrations of a driver convicted more than once in a ten-year period for the length of the license suspension, unless the offender keeps a functioning interlock device or the suspension would cause undue hardship to someone who depends on the vehicle.

Probation and Treatment After a Second Offense

Probation may last up to two years for a misdemeanor DUI conviction. The offender must complete a mandatory substance abuse evaluation and any treatment the counselor requires.

The 10-Year Lookback

Alabama measures prior offenses using a ten-year lookback period. If the prior DUI conviction falls outside the ten-year window, the current offense is sentenced as a first offense. The lookback runs from date of prior conviction to date of the current offense.

Third-Offense DUI Penalties in Alabama

A third DUI conviction is still a misdemeanor in Alabama. The felony line sits at the fourth offense. But the required jail time under Alabama law is severe and cannot be avoided.

Jail Time for a Third Offense

The sentencing range is not less than 60 days and not more than one year in the county or municipal jail. The statute requires a minimum of 60 days that must be served in jail and cannot be probated or suspended. The judge cannot reduce this mandatory minimum or swap it for community service.

Fines for a Third Offense

The fine range is not less than $2,100 and not more than $10,100 under Alabama law. The court sets the amount within that range.

License Revocation and Interlock After a Third Offense

The offender's license is revoked for three years. After a minimum of 60 days of the revocation period, a court order and proof of installation start the required three-year interlock period. Successful completion of the interlock period commutes the remaining revocation.

Probation and Treatment After a Third Offense

Probation may last up to two years for a misdemeanor DUI conviction. Mandatory substance abuse evaluation and treatment apply. The 60-day mandatory jail minimum means the offender serves at least two months first. Probation starts afterward.

Fourth or Subsequent DUI in Alabama: Felony Jail and Prison Time

How many DUI convictions before prison in Alabama? The fourth DUI conviction crosses the felony line. Under Alabama law, a fourth or subsequent DUI is a Class C felony.

DUI Prison Time for a Fourth Offense

The sentencing range is not less than one year and one day and not more than ten years in state prison. The minimum sentence must include imprisonment of at least one year and one day. The statute also requires a mandatory minimum of ten days that must be served in the county jail. Beyond the mandatory ten days in the county jail, the remainder of the sentence may be suspended or probated. But suspension or probation requires the defendant to enroll in and finish a state-certified chemical dependency program. The court referral officer must recommend the program. The sentencing court must approve it.

Where the total sentence does not exceed three years, confinement may be in the county jail. Where the sentence does not exceed one year and one day, confinement shall be in the county jail.

Fines for a Fourth or Subsequent Offense

The fine range is not less than $4,100 and not more than $10,100 under Alabama law.

License Revocation and Interlock After a Fourth Offense

The offender's license is revoked for five years. After a minimum of one year of revocation, a court order and proof of installation start the required four-year interlock period. Successful completion of the four-year interlock period commutes the remaining revocation.

Lifetime Felony Enhancement

Once a person has a felony DUI conviction on their record, every subsequent DUI arrest is prosecuted as a felony. This rule applies no matter how many years have passed. Under Alabama law, the ten-year lookback window no longer applies after a felony DUI. A person with a felony DUI from 20 years ago who is arrested today faces Class C felony charges.

The Alabama habitual felony offender law does not apply to felony DUI convictions under this section. But prior DUI convictions may be considered under the Alabama Sentencing Guidelines.

Aggravating Factors That Double Alabama DUI Minimums

Alabama law adds harsher penalties when certain aggravating factors are present at the time of the DUI offense. Under Alabama law, the mandatory minimum sentence is at least doubled when the DUI involved either of the following:

• A BAC of 0.15 percent or greater
• A child under 14 years old as a passenger, where the driver was over 21

Injury to someone besides the offender and refusal to provide a blood alcohol concentration do not double the sentence. On a first conviction each one requires a one-year ignition interlock instead.

The doubling applies to the mandatory minimum sentence for each offense tier. In practice, this means:

• Second offense – The 5-day mandatory minimum doubles to ten days in jail
• Third offense – The 60-day mandatory minimum doubles to 120 days in jail
• Fourth or subsequent offense – The court must impose at least double the minimum punishment that would otherwise apply

A first-offense DUI has no statutory mandatory minimum jail term. Where a misdemeanor DUI involves a 0.15 BAC, Alabama law sets the minimum punishment at one year of imprisonment, all of which may be suspended except for the days a second or third offense requires. These factors also bring longer ignition interlock requirements and longer license consequences.

Each factor requires the court to impose at least double the minimum punishment. Alabama law does not say how the two combine when both are present, so the court sentences within the statutory range.

Alabama DUI Probation: Terms, Conditions, and What to Expect

Alabama DUI probation is how courts supervise offenders after sentencing. Probation may not exceed two years for misdemeanor DUI convictions. For felony DUI convictions, probation may extend to five years. Under Alabama law, the maximum probation period is extended until all ignition interlock requirements have been completed.

Standard Probation Conditions

Courts usually order these conditions as part of an Alabama DUI sentence:

• Completion of a DUI or substance abuse court referral program
• Substance abuse evaluation and any treatment recommended by the counselor
• Abstention from alcohol and controlled substances
• Random drug and alcohol testing
• No new criminal arrests
• Compliance with all ignition interlock device requirements
• Payment of all fines, court costs, and any ordered restitution
• Regular reporting to a probation officer (for supervised probation)

Consequences of Violation

Breaking probation conditions can get probation revoked. If probation is revoked, the court may impose the rest of the suspended jail or prison sentence. The exposure runs up to the statutory maximum for the offense tier. Full revocation is reserved for violations such as a new arrest or conviction, absconding, possessing a firearm, or failing to complete an ordered program; other violations draw short periods of confinement first. For a first offense, that means up to one year in county jail. For a felony fourth offense, the court could impose the balance of up to ten years in state prison.

For felony DUI cases, the court may also place the defendant on house arrest with electronic surveillance during probation. This applies where monitoring equipment is available.

Ignition Interlock and Collateral Felony DUI Consequences

An ignition interlock device is a breath alcohol testing unit attached to a vehicle's ignition system. Under Alabama law, the device prevents the vehicle from starting if the operator's breath sample registers a BAC of 0.02 or higher. The device records all start attempts and must be serviced and calibrated every 30 days.

Interlock periods grow with each offense tier. On a standard first offense the offender may elect 90 days of interlock to stay the license suspension. A second offense requires two years. A third requires three years. A fourth or subsequent conviction requires four years. Any interlock violation extends the required period by six months.

Collateral Consequences of a Felony DUI

A felony DUI conviction reaches far beyond fines and jail time. These include loss of firearm rights, employment opportunities, and immigration status.

Firearm rights – Alabama law bars anyone convicted of a felony within the previous five years from owning or possessing a firearm, and federal law restricts firearm possession after a felony conviction.

Voting rights – A felony DUI is not one of the felonies that disqualify an Alabama voter, so the conviction alone does not cost the right to vote.

Employment – A permanent felony record hurts job chances, professional licensing, and career growth.

Immigration – A DUI conviction can affect a non-citizen’s immigration status, but the outcome turns on federal immigration law, not on Alabama’s felony label. A non-citizen facing a DUI charge should speak with an immigration attorney.

These added effects stretch the gap between a misdemeanor third offense and a felony fourth offense well beyond the prison sentence itself.

DUI Controlled Substance in Alabama: Drug DUI Penalties

A DUI controlled substance charge in Alabama carries the same penalties as an alcohol DUI. Under Alabama law, driving under the influence of a controlled substance is unlawful. The substance must render the person incapable of safely driving.

It is also unlawful to drive while under the combined influence of alcohol and a controlled substance. Again, the substance must render the person incapable of safely driving.

It is also unlawful to drive while under the influence of any substance that impairs mental or physical faculties. The impairment must render the person incapable of safely driving.

The penalty tiers – fines, jail, probation, and license consequences – are the same as for alcohol DUI offenses. A controlled substance DUI counts as a prior offense for lookback purposes just as an alcohol DUI does.

Prescription drugs can form the basis of a DUI charge if they impair driving. This is true even when the drug was lawfully prescribed. These cases often turn on Drug Recognition Expert reviews and blood tests, not breath tests. The legal standard is impairment – not whether the substance was legal to possess.

How a DUI Lawyer Works to Lower Your Sentence

The ranges on this page are not a forecast. Where a case lands inside a range often comes down to the work done before sentencing day.

A defense lawyer starts with the stop itself. Why did the officer pull the driver over? What does the dash or body camera show? Were the field sobriety tests done the way police officers are trained to do them? Thin answers to those questions shrink the case the state is holding.

Next comes the testing. A defense lawyer looks at how the machine that measured the blood alcohol level was kept up and who ran it. On a blood case, the lawyer traces how the sample was drawn, stored, and handled before it reached the lab. One gap in that trail can put a number in doubt.

Then there is the person standing in front of the judge. Treatment already under way. Steady work. A clean record otherwise. Letters from an employer or a pastor. A lawyer gathers all of it and puts it in front of the court. Showing up with that record built reads very differently than promising to build it later.

None of this is fast work. The sooner a lawyer sees the file, the more of it gets done well.
