Ignition interlock requirements in Arizona
In most states the interlock order and the insurance filing are two parallel obligations that happen to arrive together. Arizona is the state where one statute joins them: the department may not issue the interlock-restricted license until proof of financial responsibility has been filed. The sequence is fixed, and it is the opposite of the order most people attempt.
We do not sell interlocks. We do not install, service, calibrate or lease them, we take nothing from anyone who does, and there is no approved-provider list on this site. The state that issued your order publishes the list of devices it certifies; that list is the authority and it is free.
The sentence that sets the order of operations
Where a driver's license or a non-resident's driving privilege has been suspended or revoked under the Arizona driving-under-the-influence and implied-consent sections, the department shall not terminate that suspension or revocation, or issue a special ignition interlock restricted driver license, until the person provides proof of financial responsibility.
A.R.S. sec. 28-3319(A) · in force 2026
This is the sentence that makes Arizona different: the department “shall not terminate the suspension or revocation or issue a special ignition interlock restricted driver license … until the person provides proof of financial responsibility.” One statute wires the interlock license and the SR-22 together.

Read it as a dependency and the practical consequence is obvious. Installing the device first achieves nothing on its own. Arranging the insurance first is what unblocks everything downstream, including the restricted license that makes the device worth having.
The same section covers the person who never had a license: where an unlicensed resident is denied a license or permit following one of those actions, the department does not issue one until the same proof is provided.
What counts as proof
Arizona lists the routes explicitly rather than leaving them to regulation. A person may file a certificate of insurance, or lodge certificates of deposit or cash.

The certificate route is the ordinary one, and the mechanics are the familiar ones: the carrier files a written certificate with the director stating that a motor vehicle liability policy is in effect for the benefit of the person required to furnish proof, in a form the director prescribes. You do not file it. The insurer does.

The amounts, and the 2020 step
An Arizona certificate attests to $25,000 per person / $50,000 per accident / $15,000 property damage — 25/50/15 — for policies issued or renewed on or after 1 July 2020.
A.R.S. sec. 28-4009(A)(2)(b) · policies issued or renewed on or after July 1, 2020
The previous figures are still in the same subsection, one paragraph above, and they are considerably lower: $15,000 / $30,000 / $10,000. They now apply only to policies issued or renewed on or before 30 June 2020, and to self-insurers. Any Arizona page still quoting those is reading the wrong paragraph.

What the dependency means in practice
Most people in this position work in the order the problem appeared: the court mentioned a device, so they look for a device. In Arizona that order wastes the most expensive weeks of the process.
The statute makes the insurance filing a precondition of the department acting at all — both of terminating the suspension and of issuing the interlock-restricted license. An installed device on a vehicle you may not lawfully drive achieves nothing, and the installation clock and the lease usually start on the day of fitting rather than on the day the license arrives.
So the sequence that costs least is: find a carrier that will file, get the certificate filed, and let the license application and the installation follow. The part of that sequence that takes unpredictable time is the first step, because carriers are not obliged to file and a driver with a DUI-related suspension is exactly the profile some of them decline.
The suspension is the thing being lifted, not the device requirement
A distinction worth holding onto while reading the section. The sentence quoted above is about what the department may not do: it may not terminate the suspension or revocation, and it may not issue the special license. It is a brake on the agency, not an additional obligation on you.
That framing explains why the proof requirement survives whatever happens with the device. Filing the certificate releases the brake. It does not discharge the interlock condition, which came from a different document and ends on its own terms.
The same section reaches the person who never held a license. Where an unlicensed resident is denied a license or permit following one of those actions, the department does not issue one until the same proof is provided — so “I do not have a license to lose” is not a way around the requirement. It is a way of arriving at the same requirement from the other side.
Filing without a vehicle in Arizona
The certificate route contemplates this directly. The certificate must designate by explicit description or appropriate reference all motor vehicles covered, unless the policy is issued to a person who is not the owner of a motor vehicle.
That clause is the statutory hook for a non-owner filing: the drafter anticipated a policy with no vehicle attached and wrote the vehicle-designation requirement to switch off for it. It is the same instrument described on the non-owner page, and it matters here because a person whose vehicle was impounded or sold after a DUI-related suspension is a common case rather than an edge one.
The section also bars registration of a vehicle in the name of a person required to file proof unless that proof is in place, which is the other half of the same idea: the state is tying both the license and the registration to the certificate rather than to the car.
The 2020 step, and who is still on the old numbers
The two sets of amounts in section 28-4009 are separated by a date and by a category, and both halves of that sentence matter.
The date is 1 July 2020. A policy issued or renewed on or after it carries the current 25/50/15 figures; a policy issued or renewed on or before 30 June 2020 carries $15,000 / $30,000 / $10,000. Since an auto policy renews at least annually, essentially nothing ordinary is still running on the older amounts — which is exactly why a page quoting them looks plausible and is wrong.
The category is the part that is still live. The subsection carrying the older figures also applies to a person holding a valid certificate of self-insurance or partial self-insurance under another section of the same chapter. So the lower amounts are not historical residue; they are a current rule for a narrow class of holder. A summary that presents them as “the old Arizona minimum” and deletes them has lost information, and one that presents them as the general minimum has lost considerably more.
This is the same structural hazard that Virginia's section produces, and California's reproduction produces, in three different states: a superseded-looking figure that is still correct text, sitting one paragraph from the figure you actually need, with nothing between them that a machine would read as a warning.
How long, and why there is no number here
This site did not locate an Arizona statute fixing the duration of the filing, and does not publish one. That is why Arizona has an interlock page and a row in the limits table but no SR-22 state page of its own: the bar for a state page here is that both the amounts and the period have been read.
The Motor Vehicle Division's notice states your period. It is the authority, and it is specific to your case in a way no published summary can be.

Common questions
Can I get an Arizona interlock license before filing an SR-22?
No. A.R.S. section 28-3319(A) says the department shall not terminate the suspension or issue a special ignition interlock restricted driver license until the person provides proof of financial responsibility.
What are the Arizona minimum liability limits?
25/50/15 — $25,000 bodily injury per person, $50,000 per accident and $15,000 property damage, for policies issued or renewed on or after 1 July 2020, under A.R.S. section 28-4009(A)(2)(b).
How long does the Arizona filing last?
This site did not locate an Arizona statute fixing the length of the filing and will not state a figure for it. The notice from the Motor Vehicle Division is the authority.
How do I give proof of financial responsibility in Arizona?
A.R.S. section 28-4076 lists the routes: a certificate of insurance under section 28-4077 or 28-4078, or certificates of deposit or cash under section 28-4084.
Does an unlicensed resident have the same requirement?
The same section addresses it: where an unlicensed resident is denied a license or permit after a DUI-related action, the department does not issue one until proof of financial responsibility is provided.
