In the state of Iowa, driving while intoxicated is commonly referred to as operating under the influence (OWI), as opposed to DUI. A person commits the offense of an OWI when they are operating a motor vehicle while under the influence of an alcoholic beverage, another drug, or a combination of different substances. An OWI is a serious charge, and the penalties and sentences associated with a conviction depend on a number of factors, including amount of past convictions, the age of the driver, and the blood alcohol concentration.

At Fitch & Stahle Law Office , we have a team of trusted lawyers licensed to practice in both Iowa and Nebraska. We have experience in criminal defense cases, including OWI cases, and our team of lawyers will stand by your side and protect your rights throughout the trial process. Here is what you need to know about Iowa OWI and DUI laws.

What is Implied Consent?

The implied consent law in Iowa requires all drivers to submit to a breath, blood, and/or urine test if the police officer determines that there are reasonable grounds to believe that the driver was operating under the influence. Our DUI defense attorney will warn you that motorists who refuse these tests generally face a license revocation of one year. If the driver has a previous OWI convicted, the revocation increases to two years.

BAC Limits in Iowa

According to our OWI lawyer and Iowa state law, drivers may not possess an alcohol concentration of .08 or above while driving a motor vehicle. If you are driving a commercial vehicle, the BAC limit is .04. As is the case with most states, Iowa follows a zero tolerance policy for drivers under 21 who are operating a vehicle while under the influence. The BAC limit for these drivers is .02.

OWI Penalties and Sentencing in Iowa

The OWI penalties and sentencing in Iowa are dependent on the amount of prior convictions. No matter your number of convictions, it is important that you contact a drunk driving attorney.

First Conviction

The first OWI offense is classified as a serious misdemeanor and is punishable by a minimum period of imprisonment of 48 hours, not to exceed one year. Also, there may be a fine of up to $1,250.

Second Conviction

The second OWI conviction is classified as an aggravated misdemeanor. The punishment is a minimum of seven days in prison, not to exceed two years. The driver also has to pay a minimum fine of $1,875 and a maximum fine of $6,250.

Third Conviction

Third and subsequent OWI convictions are class D felonies in Iowa. This is punishable bya maximum of five years in prison with a mandatory minimum of 30 days.

Additional Penalties

In addition to the prison time and fines, drivers convicted of an OWI may face license revocations, depending on how many prior convictions they have. Additionally, they are sentenced to probation, required to complete treatment, and in some cases, their vehicle is impounded.

Why You Need a Personal Injury Lawyer
By Robert Stahle August 21, 2025
What to Do After a Drunk Driving Accident in Nebraska or Iowa Being hit by a drunk driver is traumatic, confusing, and often life-altering. In the aftermath, you may be overwhelmed by medical bills, vehicle damage, missed work, and pain that doesn’t go away. On top of all that, you’re probably wondering: What are my legal rights? At Fitch & Stahle Law Firm in South Sioux City, Nebraska , we help victims of drunk driving accidents across Nebraska and Iowa understand their rights, protect their claims, and pursue the compensation they deserve. This post explains what you’re entitled to after a DUI-related crash—and what steps you should take to protect yourself. Drunk Driving Victims Have the Right to Compensation If you were injured by someone driving under the influence of alcohol or drugs, you have the legal right to seek compensation through a personal injury claim . These claims are separate from any criminal charges the drunk driver may face. In a civil claim, the goal is not to punish the offender (that’s the court’s job)—it's to recover financial damages for the harm you’ve suffered , including: Emergency medical care Long-term treatment and rehabilitation Lost income and loss of earning potential Pain and suffering Mental and emotional distress Property damage Punitive damages (in extreme DUI cases) At Fitch & Stahle , our job is to make sure you get every dollar you’re entitled to—while the at-fault party is held accountable for their reckless actions. Nebraska and Iowa Laws That Protect Drunk Driving Victims Every state handles DUI-related personal injury claims differently. Because Fitch & Stahle Law Firm is licensed in both Nebraska and Iowa , we’re uniquely qualified to navigate the laws in both jurisdictions. Here are some key legal protections available in each state: Nebraska: Dram Shop Liability : If a bar, restaurant, or alcohol-serving establishment over-served the intoxicated driver, you may be able to sue that establishment under Nebraska’s dram shop law. Comparative Negligence Rule : Nebraska follows a modified comparative negligence rule. You can still recover damages if you were less than 50% at fault for the accident. Statute of Limitations : You generally have four years to file a personal injury claim in Nebraska, but acting sooner improves your chances. Iowa: Dram Shop Law : Iowa’s dram shop law also allows claims against alcohol vendors who sell to an intoxicated person that causes an accident. These claims have special notice requirements. Modified Comparative Fault : You can recover damages in Iowa as long as you are not more than 50% at fault. Statute of Limitations : In Iowa, you typically have two years from the date of injury to file a lawsuit. Understanding which laws apply—and how to use them to your advantage—requires a legal team with experience in both states. That’s why Fitch & Stahle Law Firm is the trusted choice in Siouxland . What to Do Immediately After a Drunk Driving Crash The steps you take right after a crash can make or break your case. Here's what you should do: ✅ Call 911 and get medical help Always prioritize safety. Even if you feel okay, some injuries (like brain trauma or internal bleeding) don’t show symptoms right away. ✅ Document everything Take photos of the crash scene, vehicle damage, your injuries, skid marks, and road signs. Get names and contact info of witnesses. ✅ Get the police report A police report stating the other driver was intoxicated is critical to your claim. Ask the responding officer for details about any breathalyzer or field sobriety tests. ✅ Avoid talking to insurance companies alone Insurance adjusters may seem friendly, but they are trained to protect the company—not you. Don’t give recorded statements or accept offers without legal guidance. ✅ Contact a personal injury lawyer The sooner you speak to a lawyer, the better. At Fitch & Stahle , we offer free consultations and handle every step of your claim—from gathering evidence to negotiating with insurers and going to court if needed.
