What § 28-1461 Sets Out

A.R.S. § 28-1461 is the Arizona statute on certified ignition interlock devices. It sets out procedure and rules rather than defining an offense, so no offense class or sentence attaches to this section on its own.

A. If a person’s driving privilege is limited pursuant to section 28-1381, 28-1382, 28-1383 or 28-3319 or restricted pursuant to section 28-1402:

  1. The person shall:
  2. The department shall not reinstate the person’s driving privilege or issue a special ignition interlock restricted driver license until the person has installed a functioning certified ignition interlock device in each motor vehicle operated by the person and has provided proof of installation to the department.

H. Proof of compliance does not include a skipped or missed random sample if the motor vehicle’s ignition is off at the time of the skipped or missed sample.

How § 28-1461 Affects an Arizona Case

§ 28-1461 usually matters because of how it interacts with the charge someone is actually facing. We read it alongside the charging statute, because a definition or a procedural rule frequently decides what the State must prove, what a judge may impose, or what relief is available afterward.
