Breath Test

After a DUI arrest, you will be transported to a police station. After an arrest in Des Moines, Iowa, you will be taken to the the Des Moines metro police station. The officer will then ask you to submit to a breath test in the DataMaster testing room.

The Iowa Commissioner of Public Safety has approved the use of either the DataMaster cdm or DataMaster DMT to test a subject’s breath for the presence of alcohol. These are the evidentiary instruments approved for breath testing in the State of Iowa. 

The State of Iowa uses more than 170 DataMasters. Each DataMaster is assigned a different serial number. Many counties in Iowa with a small population have only one DataMaster instrument which is usually located at the  Sheriff’s Office or Jail. Larger police departments in Iowa may have several DataMasters assigned to their agencies.
