Ignition interlock requirement
| Item | Kansas rule |

SR-22 requirement
An SR-22 is a certificate an insurer files with the state to confirm that a driver carries the liability coverage the state requires. Some states use an FR-44 or a different form for alcohol-related offenses; where Kansas does, the sources below say so.
| SR-22 filing required after a DUI | Yes |
|---|---|
| Filing period | 1 years |
K.S.A. 40-3118(d)(1) directs the director of vehicles to require a person to acquire insurance, and the insurer to keep evidence of that insurance on file with the Division of Vehicles for a period of one year, when the person has been convicted in Kansas or another state of any of the violations enumerated in K.S.A. 8-285. K.S.A. 8-285(a)(2) enumerates violating K.S.A. 8-1567 (driving under the influence), and 8-285 states that for that purpose 'conviction' includes a diversion agreement entered in lieu of prosecution. The KDOR Division of Vehicles pages do not use the term 'SR-22'; the KDOR driving-record code sheet (DC-9) carries code FR4, 'Failure to maintain continuous liability insurance or file evidence of insurance – administrative suspension' (the description is split across two columns in the PDF; the evidence quote is the contiguous first part). sr22Years = 1 (the statutory one-year period).
What the source says (5)
- SR-22 filing required after a DUI
“for such person's insurance company to maintain on file with the division evidence of such insurance for a period of one year when a person has been convicted in this or another state of any of the violations enumerated in K.S.A. 8-285, and amendments thereto.”

- sr22Note_diversion

Exemptions and special cases
Four questions readers ask once an interlock is ordered — motorcycles, employer vehicles, medical inability to give a breath sample, and reduced-cost programs — answered as Kansas's interlock program page or statute states them.
| Question | Kansas rule |
|---|---|
| Motorcycles | Not addressed on the official pages read K.S.A. 8-1014, 8-1015, 8-1016 and 8-1017 refer only to a "motor vehicle"; the Kansas Highway Patrol Ignition Interlock Program page and FAQ, the KDOR Revocation or Suspension FAQ, form DC-1015 and the KDOR Alcohol Actions Chart do not mention motorcycles. |
| Employer-owned vehicle | Exempt with conditions K.S.A. 8-1015(e): a person restricted to an interlock-equipped vehicle may operate an employer's vehicle without a device during normal business activities, provided the person does not partly or entirely own or control the employer's vehicle or business. The exemption does not apply to a person whose privileges were restricted for the remainder of the one-year suspension period under 8-1015(a)(1) (the KDOR FAQ also cites (a)(3)). No employer notice, written proof in the vehicle or hours limit is stated; the KDOR FAQ phrases it as "during normal business hours". What the source says“may operate an employer's vehicle without an ignition interlock device installed during normal business activities, provided that the person does not partly or entirely own or control the employer's vehicle or business.” |
| Unable to provide a breath sample | Available Kansas Highway Patrol FAQ: if a customer has difficulty providing a sufficient amount of breath for a valid sample, the device can be lowered to the minimum allowable 1.5 L of breath set by NHTSA. No full waiver of the device for medical inability appears in K.S.A. 8-1014, 8-1015 or 8-1016 or on the KHP/KDOR program pages; KDOR form DC-2377 (Interlock Waiver Application) concerns reinstatement after a five-year extension of the restriction, not medical inability. What the source says“If a customer has difficulty with providing a sufficient amount of breath for a valid sample, the IID can be lowered to the minimum allowable 1.5L of breath, as set forth by NHTSA.” |
| Reduced-cost / indigent program | Available — Ignition Interlock Affordability Program (K.S.A. 8-1016(f) "reduced ignition interlock device program costs"; KDOR form DC-1016) K.S.A. 8-1016(f): a person restricted to an interlock-equipped vehicle may request reduced program costs from the KDOR Division of Vehicles; eligible if annual household income is at or below 150% of the federal poverty level, or (per DC-1016 and the KHP page) enrolled in food assistance, childcare subsidy or cash assistance under K.S.A. 39-709, or eligible for the low-income energy assistance program; if approved the person pays 50% of program costs and the manufacturer reduces the lease, installation, monthly calibration and removal charges by 50%; the reduction does not apply to costs for violations, mechanical failures, noncompliance, late fees or lockouts. Apply on form DC-1016 to Division of Vehicles, Driver Solutions (7–10 business days). Manufacturer per-device fees to the Highway Patrol are waived for approved participants (8-1016(c)(3)(B)). What the source says“If the division determines that the person is eligible for reduced ignition interlock device program costs, the person shall be responsible for paying 50% of the program costs. The manufacturer providing the person's device shall adjust the manufacturer's charge for services accordingly.” |
| Affordability Program – what is reduced and excluded (KDOR form DC-1016) | Lease, installation, monthly calibration and removal reduced by 50%; violations, mechanical failures, noncompliance, late fees and lockouts are not reduced. What the source says“the ignition interlock manufacturer shall reduce the cost of the ignition interlock lease, the installation, the monthly calibration, and removal by 50%. This reduction shall not apply to additional costs associated with violations, mechanical failures, noncompliance, late fees, or lockouts.” |
| Affordability Program – eligibility (Kansas Highway Patrol page) | One of: household income at or below 150% of the federal poverty level; enrollment in food assistance, childcare subsidy or cash assistance under K.S.A. 39-709; current eligibility for the low-income energy assistance program. The KHP page states the program is monitored by KDOR. What the source says“Your annual household income is less than or equal to 150% of federal poverty level. You are enrolled in the food assistance, childcare subsidy, or cash assistance programs pursuant to K.S.A. 39-709, and amendments thereto.” |
| Employer exemption as stated by KDOR (Revocation or Suspension FAQ) | KDOR's FAQ restates the employer-vehicle exception and its exclusion for persons restricted for the remainder of the one-year suspension under K.S.A. 8-1015(a)(1) or (a)(3). What the source says“a person who is restricted to operating only a vehicle with an ignition interlock device may operate an employer's vehicle without an ignition interlock device during normal business hours, provided that the person does not partly or entirely own or control the employer's vehicle or business.” |
| Interlock Waiver Application after a five-year extension (KDOR form DC-2377) | A person whose interlock restriction has been extended at least five years beyond the initial restriction, with no alcohol/drug occurrence, listed convictions, two or more moving violations or other suspension during the period, may apply to have the interlock-only restriction reinstated (lifted). What the source says“Your ignition interlock device restriction period must be extended at least five years beyond the initial ignition interlock device restriction;” |
| Manufacturer fees waived for reduced-cost participants (K.S.A. 8-1016(c)(3)(B)) | The monthly per-device fee manufacturers remit to the Highway Patrol is not assessed for devices used by a person found eligible for reduced program costs. What the source says“No fee described in paragraph (3)(A)(ii) shall be assessed or remitted if the ignition interlock device is installed for and used by a person who the division determines is eligible for reduced ignition interlock device program costs pursuant to subsection (f).” |

Frequently asked questions
- Is an ignition interlock required after a first DUI in Kansas?
- Yes. Under K.S.A. 8-1014(b)(1)(A) and 8-1015(b)(1), a first test failure or alcohol-related conviction with a BAC of .08 to .149 results in a 30-day suspension followed by a 180-day restriction to driving only a vehicle equipped with an ignition interlock device. With a BAC of 0.15 or greater, K.S.A. 8-1014(b)(2)(A) imposes a one-year suspension followed by a one-year interlock restriction.
- How long is the interlock period for a repeat offense in Kansas?
- K.S.A. 8-1014(b)(1)(B) provides that on a second occurrence (BAC .08–.149) the Division suspends driving privileges for one year and then restricts them for one year to an interlock-equipped vehicle; K.S.A. 8-1014(b)(2)(B) provides a one-year suspension then a two-year restriction when BAC is 0.15 or greater.
