Des Moines OWI Lawyer

Evidence-Focused OWI Defense in Polk County & Surrounding Areas

An OWI charge in Iowa moves fast. Your license can be revoked within days, and the decisions you make in the first 24 hours affect every stage that follows. At Feld Law Firm, our attorney brings a background as a private investigator into every OWI case, which means we don’t just review the police report. We examine the stop, the field sobriety procedures, the DataMaster DMT administration, and the implied consent advisory for weaknesses the prosecution may be counting on you to miss.

We’ve handled hundreds of OWI and criminal defense cases across Des Moines, Polk County, and surrounding areas. That experience gives our clients a realistic picture of where their case stands and what defense paths are available. Spanish-speaking support is available for clients who prefer to communicate in Spanish, and free consultations are available by phone or online.

OWI vs. DUI in Iowa: What’s the Difference?

Iowa uses the term OWI (Operating While Intoxicated) under Iowa Code 321J.2. Other states call the same charge a DUI or DWI. The distinction matters: Iowa’s “operating” standard is broader than driving. A person operates a vehicle under Iowa law by being in physical control of it while the engine is running, whether or not the vehicle is moving.

Under Iowa Code 321J.2, a person can be convicted of OWI on three separate bases:

• Operating a motor vehicle with a blood alcohol concentration (BAC) of .08 or more
• Operating a motor vehicle while under the influence of alcohol, drugs, or a combination of both
• Operating a motor vehicle while any detectable amount of a controlled substance is present in blood or urine

That third basis is significant. A person can face an OWI charge for a controlled substance detected days after use, even if no impairment was present at the time of driving.

How Long Does an OWI Stay on Your Record in Iowa?

An OWI stays on your Iowa driving record for 12 years from the date of the incident, not the date of conviction. Within that window, a subsequent OWI is enhanced to a second or third offense, which can mean the difference between a misdemeanor and a Class D felony. Prior OWIs outside the 12-year lookback period can’t enhance the offense level, but they can still be raised at sentencing. On your criminal record, an OWI stays permanently unless the case results in a deferred judgment and the record is expunged. That makes the outcome of your current case more consequential than it may first appear.

OWI License Revocation & the Temporary Restricted License (TRL)

Most OWI charges result in license revocation, but that doesn’t mean you stop driving entirely. Iowa allows drivers to apply for a temporary restricted license (TRL) by submitting Form 403400 to the Iowa DOT.

TRL requirements typically include:

• Installation of an ignition interlock device on every vehicle you operate
• Obtaining SR-22 insurance
• Paying a $200 civil penalty and a $20 reinstatement fee
• Completing a required class before full license reinstatement

Revocation lengths vary by offense. A first offense carries a six-month revocation if you submitted to the DataMaster breath test, or one year if you refused. A second offense carries one year if you blew and two years if you refused. A third offense results in a six-year revocation regardless of the test result.

If you are under 21 and your BAC was between .02 and .08, Iowa’s zero tolerance standard applies: your license is revoked for 60 days and you aren’t eligible for a TRL during that period.

In limited circumstances, revocation may be avoidable entirely. If the officer lacked reasonable grounds for the stop or a constitutional right was violated, the revocation may be challenged. You have 10 days from the OWI charge to notify the Iowa DOT of an appeal. This deadline is especially critical for CDL holders, whose commercial driving privileges face separate and more severe consequences.

Driving after an OWI charge without a valid TRL carries serious consequences: an additional serious misdemeanor, a mandatory $1,000 fine, and up to one year in jail.

Penalties for OWI Charges in Iowa

OWI is one of the most frequently litigated criminal offenses in Iowa because even a first offense carries mandatory jail time. The penalties escalate sharply with each subsequent charge.

Penalties by Offense Level

First OWI (serious misdemeanor): A minimum of 48 hours in jail, or a drunk-driving course as an alternative. Fines start at $1,250 plus a 15% surcharge and $100 in court costs.

Second OWI (aggravated misdemeanor): A minimum of seven days in jail. Fines of at least $1,875 plus a 15% surcharge and $100 in court costs.

Third OWI (Class D felony): A mandatory minimum of 30 days in jail, with up to five years in a correctional facility. Fines of at least $3,175 plus a 15% surcharge.

Iowa’s 12-year lookback period determines whether a prior OWI counts toward offense enhancement. The period runs from the date of the earlier incident, not the conviction date. A prior OWI from more than 12 years ago can’t elevate your current charge, but it can still be considered at sentencing.

Serious & Aggravating OWI Penalties

Certain circumstances trigger consequences beyond the standard offense levels.

OWI Causing Death
An OWI resulting in death constitutes vehicular homicide by OWI, a Class B felony carrying up to 25 years in prison, along with a six-year license revocation and ineligibility for a TRL for two years.

OWI Causing Injury
The standard license revocation for the offense level is extended by one additional year.

OWI While Driving While Revoked
Your vehicle may be impounded immediately upon arrest for at least six months or until the revocation period is complete, whichever is longer.

Deferred Judgment for a First-Offense OWI in Iowa

In Iowa, deferred judgment in an OWI case is generally available only for a first offense where the BAC was below .15 and no accident caused bodily injury. Refusing the DataMaster on a first offense typically disqualifies a person from deferred judgment, though limited exceptions apply. The outcome is at the court’s discretion, and an attorney who can make a compelling argument on your behalf can meaningfully affect whether that option is seriously considered.

How Much Does an OWI Cost in Iowa?

The fines listed in the statute are a fraction of the total financial impact. A first-offense OWI in Iowa typically costs between $6,000 and $12,000 out of pocket. A third offense can reach $20,000 or more.

Costs beyond attorney fees typically include:

• OWI offender program ($425 for a first offense / $800 for a second offense)
• Substance abuse evaluation ($100)
• SR-22 insurance (approximately $60 to $120 more per month)
• Ignition interlock device ($75 per month plus installation fees)
• Jail time if ordered ($75 per day)
• Fine (at least $1,250 for a first offense)
• Court costs ($100)
• 15% surcharge on the fine
• SCRAM bracelet if ordered (approximately $10 per day)
• Iowa DOT reinstatement penalties
• Increased insurance premiums

Even if your OWI is dismissed, a 12-hour OWI class through DMACC or a similar facility is typically still required to reinstate your full license. When you add it all up, the financial case for fighting the charge rather than accepting conviction is often stronger than people realize when they first come to us.

OWI Defense in Des Moines: Why Our Investigative Background Matters

Most OWI attorneys review a case. Our attorney investigates it. A background as a private investigator changes how evidence gets evaluated: where other attorneys see a DataMaster result, we look at whether the machine was certified, whether a 15-minute deprivation period was observed, whether the implied consent advisory was correctly given, and whether the officer was certified to administer the test. Any one of those procedural requirements, if violated, can be grounds to challenge the breath test result.

We’ve handled hundreds of criminal defense cases in Des Moines and Polk County, which means we know how the Polk County Attorney’s OWI Unit screens arrests, how cases move through the Polk County Courthouse, and what arguments are likely to carry weight with a particular judge or prosecutor.

Retaining an OWI attorney may make it possible to:

• Challenge the legality of the initial stop or arrest
• Seek exclusion of breath, blood, or urine test results based on procedural violations
• Pursue amendment or dismissal of charges
• Seek to avoid or reduce jail time
• Seek faster license reinstatement where available
• Pursue a deferred judgment and possible expungement of the record

Clients are represented personally by our attorney. We don’t pass cases to junior staff. Services start at $1,000, and we offer free consultations for anyone facing an OWI charge in Des Moines or the surrounding areas. Spanish-speaking support is available.

What to Do if You Are Pulled Over for an OWI in Des Moines

The tips below are for informational purposes only and do not constitute legal advice nor do they create an attorney-client relationship.

From the moment of the stop, officers are documenting everything: your driving behavior, how you respond, your speech, your appearance, and any field sobriety performance. The officer works for the state and is trained to build a case. Understanding what’s voluntary and what isn’t gives you a better chance of not adding to that case yourself.

Decline Field Sobriety Tests
The walk-and-turn, horizontal gaze nystagmus, and one-leg stand tests are voluntary. Declining them doesn’t by itself result in license revocation. Research has shown that entirely sober individuals fail these tests at measurable rates. If an officer already suspects impairment, a poor performance will be used against you. A strong performance won’t necessarily get you released.

Decline the Preliminary Breath Test (PBT)
The PBT administered at the roadside is also voluntary. Its results can be used to build the officer’s case for arrest and to justify bringing you to the station. Blowing 0.00 doesn’t end the stop. An officer who believes you may be on drugs can still take you in for a urine test. Declining the PBT removes a piece of evidence the officer may use to seek more.

Invoke Your Right to an Attorney
Telling the officer you want to speak with an attorney limits the questions they can legally ask and restricts the evidence they can gather. Invoke that right clearly and continue to invoke it at the station. Officers sometimes continue questioning after you invoke. Keep asking for an attorney and, if possible, ask that the interaction be recorded.

Invoke Your Right to Remain Silent
Don’t discuss the facts of the stop or your evening with law enforcement. Miranda rights apply to questioning, but not to the decision to take the DataMaster breath test at the station.

Consider Taking the DataMaster at the Station
The in-station DataMaster DMT is a different decision from the roadside PBT. Refusing the DataMaster on a first offense doubles the license revocation period and typically disqualifies you from deferred judgment. If your BAC comes in below .15 on a first offense, deferred judgment may be available, which may result in dismissal and expungement of the charge. This is exactly the kind of decision where speaking with an attorney before you decide can matter significantly.
