What does Arizona's implied consent law require from a person arrested for DUI?

Arizona's implied consent law requires that individuals arrested for DUI submit to a test or tests chosen by a law enforcement officer to determine their blood alcohol concentration (BAC) or the presence of drugs. This law is designed to promote compliance with testing for intoxication, as refusal to submit to such testing can lead to certain penalties, including license suspension.

The rationale behind this law is to facilitate the collection of evidence necessary for prosecuting DUI offenses. By consenting to testing when they are arrested, individuals contribute to the legal process, which helps ensure public safety on the roads. A law enforcement officer can choose the type of test based on the circumstances of the arrest and the behavior exhibited by the driver.

In contrast, simply choosing one of the test options or a test specified by a POST officer does not encompass the full scope of what the law entails, as it specifically allows law enforcement discretion in determining the appropriate tests. Additionally, refusing testing outright would result in penalties and does not align with the obligations set forth under Arizona's implied consent law. Therefore, the correct interpretation of the law involves the requirement to submit to tests as directed by law enforcement.
