Information on Iowa DWI and Ignition Interlock Laws


Iowa’s OWI law states that it is unlawful to operate a motor vehicle in Iowa while under the influence of an alcoholic beverage or other drugs, or a combination of such substances; having a blood alcohol concentration (BAC) of .08 or more or having any amount of a controlled substance in one’s body.

Iowa’s implied consent law means that if you operate a motor vehicle in the state, you agree (consent) to have a blood, breath and/or urine test performed to determine alcohol level or presence of drugs, whenever a peace officer has reasonable grounds to believe you are operating under the influence. If you are arrested for driving with a BAC of .08 or more, your license will be suspended for 180 days. This is separate from any additional suspensions, fines or jail time a court may order if you are convicted of OWI in the state of Iowa.

If you install a car breathalyzer (ignition interlock) and apply for — and receive — a temporary restricted license, you can continue to drive during your suspension period.


Criminal sanctions are determined by the court if you are convicted or plead guilty to operating while impaired (OWI). IA Sanctions can include jail time, fines and additional license suspension. They may also require you to have an interlock device installed for a longer period of time. For more information, visit
