Alaska DUI Statute: BAC Limits, Penalties, and DMV Deadline

Alaska DUI penalties start with a mandatory 72 hours in jail and a $1,500 fine for a first conviction and climb from there: a second offense within 15 years brings at least 20 days in jail and a $3,000 fine, and a third offense within 10 years becomes a class C felony carrying at least 120 days in jail and a $10,000 fine.¹ Those are the criminal penalties. A separate DMV process can revoke your license eight days after arrest unless you request a hearing within seven days.

BAC Limits That Trigger a Charge

The standard legal limit is 0.08% blood alcohol concentration, measured by a chemical test taken within four hours of driving.¹ Two groups are held to tighter thresholds. Commercial drivers can be charged at 0.04%.² Drivers under 21 face a zero-tolerance rule where any detectable alcohol is enough.³

Testing is done by breath or blood. Breath samples are analyzed on state-approved instruments like the Datamaster DMT, operated by certified personnel.⁴ Blood draws require a qualified medical professional and go to a certified lab. Alaska does not add a separate enhanced-penalty tier for high BAC results; the penalty level is driven entirely by how many prior convictions you have.

First-Offense Penalties

A first DUI is a class A misdemeanor. The statutory minimum is 72 consecutive hours in jail, a fine of at least $1,500, and a court-imposed license revocation of 90 days.¹ You will be required to install an ignition interlock device for at least six months once your driving privileges are restored. Probation typically includes an alcohol education program through the state’s Alcohol Safety Action Program.⁵

Second-Offense Penalties

A second DUI within 15 years is still a class A misdemeanor, but the floor rises to 20 days in jail, a $3,000 fine, and a one-year court-imposed license revocation.¹ Courts commonly order a substance abuse evaluation, and completing whatever treatment it recommends becomes a probation condition.

Felony DUI: Third Offense and Beyond

A DUI becomes a class C felony when you have two or more prior convictions within the 10 years before the current offense. Watch the two lookback windows: second-offense misdemeanor status uses a 15-year window, but the felony threshold uses 10 years. Two priors that are 12 years old put you back in second-offense territory, not felony territory.

Mandatory minimums for felony DUI climb by offense:

Third offense: 120 days in jail, $10,000 fine
Fourth offense: 240 days in jail
Fifth or subsequent: 360 days in jail¹

The court-ordered license revocation for a felony DUI runs at least three years.⁶ Judges have almost no room to sentence below the statutory floor once there is a conviction, which is why plea negotiations focus on reducing or dismissing the charge itself rather than softening the sentence.

A felony DUI can also result in mandatory vehicle forfeiture. For misdemeanor DUIs, the court may order the vehicle forfeited; for a felony, forfeiture is required. This applies to cars, boats, and aircraft used in the offense.

Ignition Interlock and SR-22 Insurance

Every DUI conviction requires an ignition interlock device once you can drive again. First and second misdemeanor convictions carry a six-month minimum. A felony conviction requires 60 months.¹ The DMV estimates IID costs at roughly $600 or more over 12 months, covering installation, monitoring, and calibration.⁷

You also cannot get your license back without filing SR-22 high-risk auto insurance. The filing period depends on your conviction count:

First offense: 5 years after your revocation ends
Second offense: 10 years
Third offense: 20 years
Fourth offense: lifetime⁸

The DMV estimates SR-22 coverage at roughly $2,000 per year, which over a five-year first-offense filing period adds about $10,000 on its own.⁷

The Real Total Cost

The $1,500 first-offense fine is a small piece of the bill. The Alaska DMV estimates the average total cost of a first DUI at $24,265, including court fines, sentencing costs, the IID, vehicle impound, attorney fees, the DMV administrative hearing, SR-22 insurance, license reinstatement, and mandatory education.⁷ Second and later offenses run substantially higher because revocation periods, SR-22 obligations, and fines all grow.

The Seven-Day DMV Deadline

The DMV runs an administrative license revocation that is completely separate from the criminal case. If you fail or refuse a chemical test, the officer takes your license and gives you a Notice and Order of Revocation. That paper is also a seven-day temporary license. On day eight, the DMV revokes your driving privileges automatically.⁶

You have seven days from receiving the notice to request an administrative hearing in writing. Miss the window and the revocation stands with no further review. The hearing officer decides only whether the revocation was proper, not whether you are guilty, and cannot reverse it because you need to drive to work or school.⁹

Administrative revocation lengths are:

First offense: 90 days
One prior conviction: 1 year
Two prior convictions: 3 years
Three or more prior convictions: 5 years¹⁰

These apply whether you failed the test or refused it, and the criminal court’s own revocation can run concurrently or on top.

Refusing a Chemical Test

By driving in Alaska, you have already consented to a chemical breath test if an officer has probable cause to believe you are impaired.¹¹ Refusal does not sidestep the consequences. It triggers the same administrative revocation as a failed test, and it can be introduced against you at trial. Test-refusal convictions also count as prior offenses under the same schedule as DUI convictions when tallying priors for future penalty tiers.

Consequences That Outlast the Sentence

Alaska does not allow expungement of criminal convictions. Sealing a record is available only in narrow situations: proof beyond a reasonable doubt of mistaken identity or false accusation, an overturned conviction, or a governor’s pardon.¹² A standard DUI conviction stays on your record. Licensing boards for healthcare, law, and other regulated professions routinely ask about it.

A felony DUI carries added restrictions. Under state law, you lose the right to possess a concealable firearm.¹³ Federal law adds a broader ban: anyone convicted of a crime punishable by more than a year in prison cannot possess any firearm, and a class C felony in Alaska qualifies.¹⁴

If you hold a commercial driver’s license, a DUI in any vehicle disqualifies your CDL for one year on a first offense and for life on a second, with a possible reinstatement petition after 10 years. Hauling hazardous materials at the time pushes the first-offense disqualification to three years. A test refusal counts the same as a conviction for CDL purposes.

A DUI conviction can also make you inadmissible to Canada under its immigration law.¹⁵ You may qualify for “deemed rehabilitation” after enough time has passed, or apply for formal criminal rehabilitation or a temporary resident permit.¹⁶
