Ignition interlock financial assistance: help paying

Several states make interlock companies discount or waive costs for drivers who can't afford them, and some courts can reduce fees or set payment plans. Ask before you install: most programs need an application or a court finding first.

What each state offers

From each state's statute or program page, for the 33 states we've finished checking.

State	Help paying
Alabama	ALEA administers the Alabama Ignition Interlock Indigent Fund. To qualify, you need a court order granting indigency status and a completed affidavit of substantial hardship.¹
California	The DMV low-income IID program lowers what you pay for the device based on income. To apply you show last year's federal tax return, your last three months of income statements, or EDD unemployment verification.²
Colorado	The Financial Assistance for Ignition Interlock program covers part of your lease charges for each month you hold a valid restricted license, up to $400 in total. It does not pay back costs from before you were approved, and the income limit is set as a percent of federal poverty guidelines.³
Connecticut	The DMV runs no fund for interlock costs. Some vendors discount for low-income drivers, and to qualify you provide a letter from the Connecticut Department of Social Services showing you take part in SNAP or LIHEAP.⁴
Delaware	The DMV must set up an installment payment plan, which the service provider administers, and an indigent plan for people with very little income. You have to meet criteria and provide documentation, and we could not find what those criteria are, so ask the IID Unit or your provider.⁵
Florida	FLHSMV and the seven vendors run a discount program that began on September 1, 2020, and each vendor sets its own eligibility and terms. A court may also direct part of your DUI fine toward installation cost if you cannot pay.⁶
Georgia	Georgia has a financial hardship exemption from installing a device under O.C.G.A. 42-8-111(a)(1). If you receive it, you cannot get a limited permit until 12 months of the suspension have been served. The eligibility terms were not available to us, so ask DDS how to qualify.⁷
Idaho	A court may let you use the court interlock and electronic monitoring fund, and the judge makes that decision. The fund is based on a court finding of financial hardship, so the court needs evidence of your situation.⁸
Illinois	If the Secretary of State finds you indigent, the provider installs, monitors and removes the device free of charge and is reimbursed from the Indigent BAIID Fund. Lockout and reset fees remain yours to pay.⁹
Kansas	The Ignition Interlock Affordability Program lets eligible participants pay 50% of program costs. You may qualify through household income at or below 150% of the federal poverty level, certain public benefits, or low-income energy assistance eligibility.¹⁰
Kentucky	If your income is at or below 200% of federal poverty guidelines, the Transportation Cabinet can reduce provider fees. You pay 75% of fees at 150-200%, 50% at 100-150% and 25% at or below 100%, and you apply with KIIP Affordability Application TC 94-188.¹¹
Maine	Certified installers must cut your total costs by at least 50% if your adjusted gross household income is no more than 150% of the federal poverty guidelines. You show this with your most recent federal income tax return.¹²
Maryland	If you are on assistance, approved providers must offer 50% off their rental rates, and the $47 enrollment fee can be waived. The MVA may waive the enrollment fee for people on medical or food assistance. The waiver request is Form DC-212, the Ignition Interlock Participation Fee Waiver Application, which you can find at mva.maryland.gov/media/190.¹³
Michigan	Manufacturers must provide the device free to low-income drivers, meaning those whose prior-year gross income was under 150% of the federal poverty line.¹⁴
Minnesota	Manufacturers must provide installation, servicing and monitoring to indigent participants at a discounted rate under standards set by the commissioner. The discount amount and who qualifies were not available to us.¹⁵
Mississippi	For a driver found indigent, the Department of Public Safety pays the vendor for one vehicle per offender, drawing on the Interlock Device Fund. The state pays up to $50 for installation, up to $50 for leasing, monitoring and maintenance, and up to $30 for removal.¹⁶
Missouri	Providers must offer a discounted fee if your income is at or below 150% of the federal poverty level, and you then pay 10% of the device cost. Extra costs from noncompliance are not discounted. You can show eligibility with last year's federal tax return, income statements from the last three months, or a court order.¹⁷
Nebraska	If the DMV, the court or the Board of Pardons finds you indigent and unable to pay for installation, removal or maintenance, the costs can be paid from the DMV Ignition Interlock Fund. Payment happens only if money is available in the fund.¹⁸
New Hampshire	If you cannot afford the full cost, you can request a hearing under Saf-C 203 and file affidavit DSSP 358 within 10 days of the request. The help comes as a financial hardship credit from the provider's 2 percent reserve account.¹⁹
New Mexico	The Ignition Interlock Indigent Device Fund, run by the NMDOT Traffic Safety Division, can help if indigency is granted and money is available in the fund. It covers one vehicle per offender.²⁰
Ohio	Counties and municipalities run an indigent drivers interlock and alcohol monitoring fund that can help with the cost of the device. The court has to find that you lack the means to pay for using the device.²¹
Oklahoma	If you are actively receiving TANF or SNAP benefits, you may qualify for BOT IDAP Affordability Accommodations. The manufacturer pays a credit of no more than $25 per 30 days, up to $150 for a first revocation, $300 for a second and $450 for a third or later. Apply by emailing proof to boardoftests@bot.ok.gov.²²
Oregon	Oregon's Indigent Ignition Interlock Device Program pays for installation, monitoring and removal. It is run by the OHA together with the OSP IID Oversight Program. You qualify if you live in Oregon, an Oregon court ordered the interlock after a DUII, and you are enrolled in SNAP. ORS 813.603 also lets the department waive or defer your responsibility to pay, in whole or in part, using SNAP-based indigence criteria.²³
South Carolina	If you cannot afford the device, you can apply to the Ignition Interlock Device Fund with an affidavit of indigency (PPP Form 1307). You are presumed indigent if your net family income is at or under the federal poverty guidelines, and the help is not open to habitual offenders in the program under 56-1-1090(A). DMV may waive the device if a medical condition prevents you from using it properly. In that case the license is suspended for the length of time the interlock license would have been required.²⁴
Tennessee	If a court finds you indigent, a manufacturer cannot refuse you service as long as money is available in the Electronic Monitoring Indigency Fund, which the Tennessee Dept. of Treasury administers.²⁵
Texas	If the court finds you indigent while you are on deferred adjudication, it may waive the installation charge and cut the monthly monitoring fee by 50%. Courts may also set a payment schedule up to twice the length of the order if you can't pay.²⁶
Utah	If you are on probation, you can file an affidavit of indigency, and if the court finds you indigent it may waive costs or let you pay in installments. The provider covers the costs the court waives.²⁷
Vermont	Manufacturers must discount installing, leasing and removing the device by 50% if you show proof of 3SquaresVT, LIHEAP, Reach Up or similar benefits from another state.²⁸
Virginia	Providers keep an indigency fund, and fees can be reduced if the court declares you indigent and the Commission approves the reduction.²⁹
Washington	The Department of Licensing runs an indigent assistance program funded by the $21 fee, and that fee may be waived for indigence. The criteria for qualifying were not available to us.³⁰
West Virginia	The DMV waives installation and removal fees for people it finds to be indigent. The DMV sets the application procedure by rule.³¹
Wisconsin	If your household income is at or below 150% of the nonfarm federal poverty line, the court can limit what you owe to one-half of the cost of equipping each vehicle and one-half of the per-day cost of maintaining the device. Other fees, such as violation resets, are not reduced.³²
Wyoming	If you are eligible for the federal SNAP program, the Ignition Interlock Assistance program has the state pay half of your device costs and waives the $100 administrative fee.³³

How to ask

Bring proof of income (a benefits letter, pay stubs or a tax return) to the court or the agency named in your state's row, and ask the interlock company whether it has its own reduced-rate program. Get any discount in writing before the install appointment.
