Nebraska DUI laws: .08 adult BAC, 15-day ALR temp licenses, and interlock rules that dominate both first and repeat cases

Nebraska DUI law is not just an adult .08 rule. Official state sources split the issue into the criminal DUI offense, the implied-consent refusal offense, and the DMV's Administrative License Revocation process after arrest. The practical Nebraska details are the lower .02 under-21 and .04 commercial thresholds, the 15-day temporary license and 10-day ALR hearing deadline, the fact that a first failed-test ALR is 180 days while a refusal ALR is 1 year, and the large role of ignition interlock. Nebraska's statutes and DMV materials also make clear that repeat convictions look back 15 years and can move quickly into long revocations and felony territory.

Overview

What this page helps you verify

A useful Nebraska DUI page should start by separating the state's three tracks. First is the underlying DUI offense, which can be based on impairment or on unlawful alcohol concentration. Second is the implied-consent refusal problem, which Nebraska treats as its own offense and also punishes administratively. Third is Administrative License Revocation, which begins at arrest rather than after conviction. The strongest Nebraska-specific details are the short ALR deadlines, the interlock-permit rules, and the 15-year repeat-offense lookback.

Usually needed

Documents and information to prepare

  • The citation, temporary license, and any Notice of Administrative License Revocation paperwork served by law enforcement
  • The ALR hearing petition if you are contesting the administrative revocation
  • An Ignition Interlock Permit application or certified Nebraska court order if you are pursuing the interlock route
  • Proof that an approved ignition interlock device has been installed on each vehicle you will operate
  • Any reinstatement items the DMV requires before full relicensing, including the reinstatement fee, surrender affidavit if needed, testing, and SR-22 proof if your court revocation requires it

Typical flow

What the process often looks like

  1. Identify first whether the immediate problem is a failed chemical test, a test refusal, a court conviction, or more than one of those at the same time.
  2. Check the ALR deadline immediately, because Nebraska says the petition to contest an administrative revocation must be mailed within 10 days of notice.
  3. Decide early whether to fight the ALR hearing or waive it and pursue an ignition interlock permit, because Nebraska says filing the ALR hearing petition blocks the normal ALR-based IIP path unless the court later orders interlock.
  4. Before driving again, confirm that the ALR or court revocation, the interlock period, and the DMV reinstatement requirements have all been satisfied.

Core offense rules

Nebraska DUI can be proved by impairment or by unlawful alcohol concentration

That is the first correction a state-specific page should make.

  • Nebraska statute makes it unlawful to operate or be in the actual physical control of a motor vehicle while under the influence of alcoholic liquor or any drug.
  • The same statute also makes it unlawful to drive with .08 or more alcohol in blood or breath.
  • Nebraska's driver manual adds two lower threshold lanes that matter in practice: .02 for drivers under 21 and .04 when operating a commercial motor vehicle.

ALR timing

Nebraska's first urgent deadline is the DMV revocation process that starts at arrest

This is often more immediate than the court date.

  • Nebraska DMV says law enforcement can immediately confiscate the license after a DUI arrest and that eligible drivers may receive a temporary license for 15 days.
  • The same DMV page says a first failed-test ALR is 180 days, a subsequent failed-test ALR within 15 years is 1 year, and a refusal ALR is 1 year.
  • Nebraska says the petition to request an ALR hearing must be mailed within 10 days of notice being served.
  • The DMV also says that if you pursue the ALR hearing, you are not eligible for the normal ALR-based ignition interlock permit path unless the court later orders interlock for the DUI offense.

Interlock rules

Ignition interlock is a central Nebraska DUI consequence, not a side issue

This is where Nebraska differs from states that treat interlock as mainly optional or repeat-offender relief.

  • Nebraska's first-offense DUI sentencing statute requires the court to revoke the license for 6 months and to require ignition interlock for the revocation period.
  • The driver's manual says that if the driver waives the ALR hearing, the driver may serve all or part of the ALR revocation period on an Ignition Interlock Permit if eligible.
  • For a refusal ALR, Nebraska's manual says the offender must wait 90 days after the temporary license expires before applying for the interlock permit, which then runs for the balance of the 1-year ALR period.
  • Nebraska law and DMV guidance also make clear that the permit is limited to Class O or Class M drivers and is not valid for operating a commercial motor vehicle.

Repeat and aggravated cases

Nebraska's repeat-offense system reaches back 15 years and escalates sharply

That is the practical reason the record history matters so much in Nebraska DUI cases.

  • Nebraska's repeat-offense statute uses a 15-year lookback for prior convictions.
  • For longer court revocations of at least 1 year, Nebraska's interlock statute uses a 45-day no-driving period before interlock driving may begin.
  • Nebraska's sentencing statute shows that by the third conviction level the case can move into a 15-year revocation range, and aggravated repeat cases involving .15 BAC or refusal move into felony penalties.
  • Because of that structure, Nebraska DUI content should not flatten repeat cases into a generic 'second offense gets harsher' summary.

Accuracy notes

Where people get tripped up

  • Nebraska DUI content should separate the criminal DUI offense, the implied-consent refusal offense, and Administrative License Revocation. The state publishes them as overlapping but distinct problems.
  • The 10-day ALR petition deadline and the 15-day temporary license are core Nebraska operational details and belong near the top of the page.
  • Do not describe Nebraska as only an adult .08 state. Official sources also call out the .02 under-21 rule and the .04 commercial threshold.
  • Nebraska's interlock structure is unusually important. A reviewed page should mention the waiver-of-hearing route, the refusal waiting period, the Class O or M limitation, and the no-CMV rule.

FAQ

Common questions

  • What BAC is illegal for DUI in Nebraska?

    Nebraska uses .08 for most drivers. The Nebraska Driver's Manual also lists .04 when operating a commercial motor vehicle and .02 for drivers under 21.

  • Can I get an ignition interlock permit after a Nebraska DUI arrest?
