Penalties for a § 28-1464 Conviction
A.R.S. § 28-1464 is the Arizona statute on ignition interlock devices. A violation is a class 1 misdemeanor, depending on the paragraph charged and what the State can prove. The maximum exposure is 6 months in jail.
| Class | Maximum jail | Maximum fine |
|---|---|---|
| Class 1 misdemeanor | 6 months | $2,500 |
Felony ranges are set by A.R.S. § 13-702(D) and apply to a first felony conviction that is not dangerous and not repetitive. A dangerous offense (§ 13-704), a repetitive offense (§ 13-703) or a dangerous crime against children (§ 13-705) carries a longer range, and some carry mandatory prison with no probation. Misdemeanor maximums come from §§ 13-707 and 13-802; surcharges are added on top of every fine.

How Tamou Law Group Defends § 28-1464 Cases
A § 28-1464 case is decided by the paragraph the State charged, not by the statute as a whole. We start with the charging document and the disclosure, identify which subsection the prosecutor has to prove, and test whether the evidence actually reaches every element of it. Where the class turns on a fact such as value, an alleged injury, a prior conviction or the identity of the person involved, that fact is frequently the difference between a class 1 misdemeanor and something far less serious, and it is where these cases are won.
