How your BAC and refusal affect your term

Kansas uses a BAC-tiered IID schedule. For a first offense, the difference between a standard BAC (0.08–0.149) and a high BAC (0.15+) is 6 months of additional IID time. Refusing the chemical test carries the longest IID requirement at every offense level — 2 years for a first refusal versus 180 days for a first standard BAC failure. Kansas also counts DUI “occurrences” separately — a prior refusal and a prior test failure each count as their own occurrence for purposes of the tiered schedule.

Income-qualifying? Cut your costs in half. Kansas’s Ignition Interlock Affordability Program (KDOR form DC-1016) requires participating manufacturers to reduce lease, installation, calibration, and removal costs by 50% for eligible drivers. Eligibility: household income at or below 150% of the federal poverty level, OR current recipient of food assistance, childcare assistance, or cash assistance under K.S.A. 39-709, OR LIEAP eligibility. Apply through KDOR Driver Solutions when you apply for your interlock license.

How to get installed — 5 steps

  1. After your suspension, apply to KDOR Driver Solutions to restrict your driving privileges to an IID vehicle. Pay the $100 non-refundable application fee and apply for your interlock license.
  2. If you’re income-eligible, submit KDOR form DC-1016 for the 50% affordability program at the same time.
  3. Call a KHP-certified provider, confirm device certification, and schedule installation. Bring your KDOR paperwork and vehicle.
  4. Serve your full IID term. The 90-day clean-window requirement begins before you can apply for removal.
  5. To remove: ensure you have no more than 2 standard violations and no serious violations in the final 90 consecutive days. Contact KDOR Driver Solutions to initiate reinstatement.
Check affordability eligibility first. Call a provider — they can confirm certification and affordability-program availability.

Violations and the 90-day removal window

Kansas uses two violation tiers. A standard violation is a failed startup or rolling retest. A serious violation is tampering, circumvention, or a high BrAC reading on a rolling retest. To qualify for removal, you need: no more than 2 standard violations in the 90 consecutive days immediately before your reinstatement, and no serious violations at all in that window. Any violation during the 90-day window restarts the counter — meaning if you get a standard violation on day 85, you restart the full 90-day clock. Keep a clean record for the last 3 months of your term.

Additionally, a conviction for violating the interlock restriction itself adds one full year of suspension.

Kansas’s SR-22 is just 1 year — the shortest in the country. But there’s a catch: don’t file until KDOR requests it or you won’t get credit. See Kansas SR-22 costs and how the unusual filing process works →

Kansas DUI interlock FAQ

Does every DUI in Kansas require an interlock?
Yes — Kansas requires an IID for all DUI test failures, convictions, and refusals, including a first occurrence. The term depends on your BAC level and offense count: 180 days for a standard first failure (BAC 0.08–0.149), 1 year for BAC 0.15+ on a first offense, and 2 years for a first refusal.
How does the 90-day clean window work?
To qualify for removal under K.S.A. 8-1015(d), you need no more than 2 standard violations and no serious violations in the 90 consecutive days immediately before your reinstatement application. Any violation during that window restarts the 90-day counter from zero. Plan your removal application date carefully — the last 3 months of your term need to be clean.
Can I get a 50% cost reduction in Kansas?
Yes — if your household income is at or below 150% of the federal poverty level, or you receive food/childcare/cash assistance under K.S.A. 39-709, or you’re LIEAP-eligible, Kansas’s Ignition Interlock Affordability Program cuts lease, installation, calibration, and removal costs by 50%. Submit KDOR form DC-1016 when applying for your interlock license.
What is a standard vs. serious violation in Kansas?
A standard violation is a failed startup or rolling retest. A serious violation is tampering, circumvention, or a high BrAC reading on a rolling retest. Up to 2 standard violations are allowed in the 90-day window before removal. Any serious violation in that window disqualifies you from removal during that period — the window resets.
Does refusing the chemical test carry a longer IID term?
Yes — refusal carries the longest IID requirements at every offense level. A first refusal means 2 years of IID versus 180 days for a first standard BAC failure. A third refusal means 4 years versus 2 years for a third standard failure. Kansas tracks refusal and test-failure occurrences separately.
