What Is The Penalty For Driving Without Interlock In Kansas?

In Kansas, driving without a required ignition interlock device (IID) is a serious offense that can lead to additional license suspension, fines, and even jail time. If you’ve been ordered to use an interlock after a DUI conviction, removing, bypassing, or driving a vehicle without one violates state law under K.S.A. 8-1017. The penalties depend on your record and how many times you’ve violated IID requirements.
1. Understanding the Ignition Interlock Requirement
After a DUI conviction or license suspension, Kansas law often requires drivers to install an IID before regaining driving privileges. The device prevents the vehicle from starting if it detects alcohol on the driver’s breath. You must only drive vehicles equipped with the device for the court-ordered period.
- Applies to – Drivers with DUI suspensions or restricted licenses.
- Purpose – Ensures sobriety before operating a motor vehicle.
- Duration – Typically 6 months to 3 years, depending on prior DUI offenses.
2. Penalty for Driving Without an Interlock
Driving any vehicle without a required ignition interlock is considered a Class A misdemeanor in Kansas. This offense can result in severe legal consequences, especially if it’s not your first violation.
- First offense – Up to 1 year in jail and fines up to $2,500.
- Additional suspension – An extra 90 days to 1 year added to your existing restriction period.
- Ignition interlock reset – The interlock period may restart from the date of violation.
3. Tampering or Bypassing the Device
Altering, removing, or trying to bypass the IID is treated just as seriously as driving without one. Kansas law prohibits any action intended to disable or deceive the system.
- Tampering penalties – Treated as a Class A misdemeanor with potential jail time.
- Extended IID period – Courts can extend your interlock requirement up to an additional year.
- Vehicle impoundment – Law enforcement may impound your car in severe cases.
4. License Consequences
Violating IID rules also affects your driver’s license. The Kansas Department of Revenue (KDOR) can extend your restricted period or re-suspend your license entirely. You’ll need to reapply for reinstatement and pay additional fees before driving legally again.
- Extended restriction – The interlock period restarts after each violation.
- Reinstatement fees – Must pay all fines and administrative costs to regain driving privileges.
- Record impact – Each violation becomes part of your permanent driving history.
5. How to Avoid Violations
The safest way to stay compliant is to drive only vehicles with a functioning interlock device and follow all testing requirements. Regular calibration and reporting help ensure you stay in good standing with the court and the KDOR.
- Never drive another person’s vehicle without an interlock device.
- Keep up with required service appointments and maintenance logs.
- Contact your IID provider or attorney if you experience device issues.
Driving without a required ignition interlock device in Kansas is a Class A misdemeanor that can result in up to one year in jail, $2,500 in fines, and an extended restriction period. Always comply with IID orders to avoid new charges or longer license suspensions.
