Aggravated DUI in Lancaster County: The 0.15% Threshold
Many drivers assume that all first-time DUIs are treated exactly the same. In Nebraska, the severity of your punishment is directly tied to the number on the breathalyzer or blood test.
If your Blood Alcohol Concentration (BAC) registers at 0.08%, you are legally impaired. If that number reaches 0.15% or higher, the state of Nebraska classifies the charge as an "Aggravated DUI." This single threshold drastically changes how the prosecution handles your case in Lancaster County courts.
Here is exactly what changes when your BAC crosses the 0.15% line and how it impacts your freedom.
1. Mandatory Jail Time Increases
The most immediate threat of an aggravated DUI is the enhanced minimum jail sentence.
For a standard first-offense DUI (under 0.15%), the mandatory minimum jail time is 7 days if you are not granted probation. If the judge grants probation, you might serve zero days in jail.
With an aggravated DUI (0.15% or higher), the stakes are higher. The mandatory minimum remains 7 days in jail without probation. However, even if you are granted probation, the law requires a stiffer penalty. A judge will mandate that you serve at least 2 days in jail or complete 120 hours of community service as a condition of that probation. The maximum possible jail sentence is 60 days, and judges are far less lenient when the BAC is exceptionally high.
2. Your License Revocation Doubles
Losing the ability to drive to work or pick up your kids is often the hardest part of a conviction. The 0.15% threshold makes this penalty significantly worse.
A standard first-offense DUI results in a 6-month license revocation.
An aggravated first-offense DUI triggers a mandatory 1-year license revocation. You will be off the road twice as long. While you can apply for an Ignition Interlock Permit (IIP) to drive with a breathalyzer installed in your car, the extended revocation period means you will be paying monthly rental and maintenance fees for that device for a full year instead of six months.
3. Second Offenses Escalate Quickly
Nebraska law punishes repeat offenders harshly, and a high BAC accelerates those penalties.
If you have a prior DUI conviction on your record and you are arrested again with a BAC of 0.15% or higher, the charge is escalated to a Class I Misdemeanor. This carries up to a year in jail and a license revocation period lasting anywhere from 18 months to 15 years.
If this is your third offense and your BAC is over the 0.15% mark, you are facing a Class IIIA Felony. This means a minimum of 180 days in jail, potential prison time up to 3 years, up to $10,000 in fines, and a 15-year loss of your driving privileges.
4. Why the Chemical Test Must Be Challenged
Because the 0.15% threshold carries such severe consequences, the accuracy of the chemical test is the most important piece of evidence in your case.
Lincoln law enforcement primarily uses the Intoxilyzer 8000 for breath tests and draws blood at local hospitals for blood tests. Neither method is flawless.
An experienced defense attorney will immediately look at the testing procedure. We investigate whether the machine was properly calibrated within the required state maintenance windows. We check if the arresting officer observed you for the mandatory 15 minutes prior to the breath test to ensure no mouth alcohol skewed the results. If the police used a blood test, we verify that the sample was stored properly and that no fermentation occurred, which can artificially inflate the BAC reading.
A reading of 0.16% could very well be the result of a margin of error in a poorly maintained machine. If your attorney can successfully challenge the validity of that test, the prosecutor may be forced to drop the aggravated enhancement or dismiss the charges entirely.
Do not assume a high BAC reading means you have no defense. The penalties for an aggravated DUI in Lincoln are too severe to accept without a fight.
