Kansas Ignition Interlock Requirements (2026): Costs & Approved Providers
Kansas requires an ignition interlock for every DUI conviction and test failure, including a first offense. Your BAC level and offense count determine how long you’ll have it. Income-qualifying drivers can cut costs by 50% through Kansas’s affordability program. Here’s your timeline, costs, and how early removal works.

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.
Kansas KHP-certified providers
The Kansas Highway Patrol certifies devices and vendors. The KHP certified list page was temporarily unavailable during our verification — confirm current certification directly with KHP or KDOR Driver Solutions before signing. The major national providers below are expected to include Kansas-certified options.
| Provider | Monthly est. | Coverage | |
|---|---|---|---|
| Intoxalock | $60–100 | Statewide | 888-283-5899 |
| Smart Start | $70–100 | Statewide | 800-831-3299 |
| LifeSafer | $65–95 | Statewide | 800-634-3077 |
Important: Confirm current KHP certification with your provider or at KDOR Driver Solutions before signing. Guardian and ALCOLOCK are not confirmed on Kansas’s current certified list. Monthly estimates are market ranges — affordability-program participants pay 50% of these rates.

How to get installed — 5 steps
- 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.
- If you’re income-eligible, submit KDOR form DC-1016 for the 50% affordability program at the same time.
- Call a KHP-certified provider, confirm device certification, and schedule installation. Bring your KDOR paperwork and vehicle.
- Serve your full IID term. The 90-day clean-window requirement begins before you can apply for removal.
- 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.
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.
