ARIZONA STATE SENATE
Fifty-Seventh Legislature, Second Regular Session
ignition interlock devices; violation; classification
Purpose
Increases the penalty for knowingly lending a motor vehicle without an ignition interlock device to a person whose driving privilege is limited or restricted due to a driving under the influence (DUI) violation, when the person whose driving privilege is restricted is involved in a collision that causes serious physical injury or death.
Background
A person whose driving privilege is limited or restricted due to a DUI violation may not operate a motor vehicle without a functioning certified ignition interlock device, unless there is a substantial emergency. Additionally, a person may not knowingly rent, lease or lend a motor vehicle to a person whose driving privilege is limited or restricted due to a DUI violation, unless the vehicle is equipped with a functioning certified ignition interlock device, except in cases involving a substantial emergency. A person whose driving privilege is limited or restricted must notify a person who rents, leases or lends a motor vehicle that the person must meet specific requirements to operate a motor vehicle and the nature of those requirements. A violation of the prescribed ignition interlock device requirements is a class 1 misdemeanor and, if committed by a person whose driving privilege is restricted or limited, ADOT must extend the period that the person must use an ignition interlock device for up to one year (A.R.S. § 28-1464).
There is no anticipated fiscal impact to the state General Fund associated with this legislation.
Provisions
1. Increases, from a class 1 misdemeanor to a class 6 felony, the penalty for knowingly lending a motor vehicle that is unequipped with an ignition interlock device to a person whose driving privilege is limited or restricted due to a DUI violation, if the person whose driving privilege is restricted is involved in a collision that results in serious physical injury or death while operating the motor vehicle.
2. Makes technical changes.
3. Becomes effective on the general effective date.
