Alabama Under 21 DUI Law: 0.02 BAC Limit and License Suspension

informational·how to guide·Published September 18, 2026

What is the legal alcohol limit for drivers under 21 in Alabama?

In Alabama, a driver under 21 may not drive or be in actual physical control of a vehicle with a blood alcohol level of 0.02 percent or more. The adult limit is 0.08 percent. For a first violation between 0.02 and 0.08, the license or driving privilege is suspended for 30 days.

Where the Alabama under 21 rules come from

The rule is in Code of Alabama section 32-5A-191. The Alabama Driver Manual from the Alabama Law Enforcement Agency (ALEA) Driver License Division repeats the limits and explains the chemical test rule, and the ALEA driver license point system page lists the points. The Stage II suspension rule comes from Code section 32-6-7.2, and the hardship license rule from the ALEA hardship license page. This guide is current as of 2026. Confirm the rules with the Alabama Law Enforcement Agency (alea.gov) before you drive.

What the 0.02 rule covers

Section 32-5A-191(b) says a person under 21 may not drive or be in actual physical control of any vehicle with 0.02 percent or more alcohol by weight in the blood. The rule names both driving and actual physical control, so it is not limited to a moving car. The rule depends on age, so it applies with every Graduated Driver License (GDL) stage. The question page on the Alabama under 21 blood alcohol limit tests this number.

Under 21 and 21 or older: the two limits

Under 21 and 21 or older: the two limits
Point	Driver under 21	Driver 21 or older
Blood alcohol limit	0.02 percent or more	0.08 percent or more
First violation	License or driving privilege suspended 30 days (level 0.02 to 0.08)	Up to one year in jail, a fine of $600 to $2,100 (U.S. dollars), or both; 90-day license suspension
Law	Section 32-5A-191(b)	Section 32-5A-191(a) and (e)

First violation: the 30-day suspension

For a first violation with a blood alcohol level between 0.02 and 0.08, the law suspends the license or driving privilege for 30 days. This takes the place of the first-conviction penalties of subsection (e): jail, a fine and a 90-day suspension. The law tells ALEA to suspend or revoke the license of a person convicted or adjudicated under the 0.02 rule, and it names juveniles, children and youthful offenders.
For this first violation, the law also limits who may see the arrest, conviction or adjudication records. Only courts, law enforcement agencies, the person's attorney of record and the person's employer may receive them.

Which Alabama penalty applies to your case

It is your first violation and your level was 0.02 to 0.08

The license or driving privilege is suspended for 30 days.

You are under 21 and the first-violation rule does not fit your case

You are fined under the DUI section and must attend and complete a DUI or substance abuse court referral program. ALEA does not reissue your license until it has proof that you completed that program.

Your level is 0.08 percent or more

The 0.08 limit applies to drivers of every age, and the 30-day rule does not. The question page on the Alabama adult DUI blood alcohol level covers this limit. The DUI penalties in the next section apply.

DUI penalties at 0.08 or more

A first DUI conviction can bring up to one year in jail, a fine of $600 to $2,100, or both, and a 90-day license suspension. An approved ignition interlock device, installed and working for 90 days, stays that suspension. A level of 0.15 percent or more, a refused test, a child under 14 in the vehicle or another person injured brings a mandatory one-year interlock.
A second conviction brings a fine of $1,100 to $5,100, at least 5 days in jail or 30 days of community service, one year of revocation and two years with an interlock. A fourth or later conviction is a Class C felony.

Points after an alcohol conviction

ALEA's point chart gives 6 points to a conviction from a drinking-and-driving charge that did not need mandatory revocation. It also lists 6 points for admin per se and 2 points for drinking alcohol while operating a vehicle. Points count toward suspension for 2 years. After that the conviction stays on your driver record. A total of 12 to 14 points in 2 years means a 60-day suspension for any license holder.
A Stage II (restricted) license holder also has separate GDL penalties, such as an automatic 60-day suspension for a second moving violation. The guide to GDL violation fines and points for teens covers those penalties.

Alcohol and teen drivers: safety facts

Alcohol is a depressant, not a stimulant, and it slows your reflexes.
Coffee, food or a cold shower can make you feel more awake, but none of them makes you sober.
Drinking alcohol under age 21 is illegal. ALEA reports that in 2024, 22% of teen drivers in fatal crashes had been drinking.
The parent and teen driving agreement in the Driver Manual includes these alcohol promises: no alcohol or illegal drugs in the car, and no driving for 24 hours after drinking.

Key takeaways

The limit for a driver under 21 in Alabama is 0.02 percent blood alcohol. The adult limit is 0.08 percent.
The rule covers actual physical control of a vehicle, not only driving.
A first violation between 0.02 and 0.08 means a 30-day suspension of the license or driving privilege, instead of the first-conviction DUI penalties.
At 0.08 or more, the DUI penalties apply, starting with up to one year in jail, a $600 to $2,100 fine, or both, and a 90-day suspension.

Alabama under 21 DUI: common questions

Can I get a DUI in Alabama under 21 with one drink?

The law sets a blood alcohol level, not a number of drinks. For a driver under 21, that level is 0.02 percent, one quarter of the 0.08 adult limit. At 0.02 or more, a driver under 21 breaks the law. The safe choice is no alcohol at all before you drive.

How long is the license suspension for an under 21 DUI in Alabama?

For a first violation with a blood alcohol level between 0.02 and 0.08, the suspension is 30 days. A driver under 21 who does not fit that first-violation rule is fined and must complete a DUI or substance abuse court referral program before ALEA reissues the license. At 0.08 or more, a first DUI conviction brings a 90-day suspension.

Does an under 21 DUI show on my record?

For a first violation between 0.02 and 0.08, the law lets only courts, law enforcement agencies, your attorney of record and your employer receive records of the arrest, conviction or adjudication. This limit covers only that first violation.

Is the 0.02 limit the same for a learner or Stage II license?

Yes. The 0.02 limit depends on your age, not your license stage. It applies to everyone under 21, including a Stage I learner, a Stage II restricted holder and a Stage III driver. Once you turn 21, the 0.08 limit applies to you, whatever license you hold.

Can I get a hardship license after a DUI in Alabama?

No, not after a DUI conviction. ALEA says a person adjudicated or convicted of DUI under Alabama Code section 32-5A-191 is not eligible to apply for a hardship license. The under-21 0.02 rule is subsection (b) of that same section, and the adult 0.08 rule is subsection (a).

What if I refuse the breath test in Alabama?

Every driver on Alabama public highways is deemed to have agreed to a chemical test of blood, breath or urine for alcohol. The Driver Manual says a driver arrested for DUI who refuses a breath test has the license suspended. A refusal does not help in court either: on a first DUI conviction, a refused test adds a mandatory one-year ignition interlock.
