Missouri Ignition Interlock Requirements

Operating a motor vehicle with a blood alcohol content of .08% or higher is considered a DWI in Missouri, and offenders risk significant penalties. For a first offense, offenders can receive up to six months in jail and fines of up to $1,000. They may also have their license suspended for 30 days, plus an additional 60 days of license restrictions. Offenders who need to drive or for whom being without a vehicle is a hardship can apply for Restricted Driving Privileges, but they need to install an ignition interlock device from a trusted provider like Intoxalock. In some cases, an ignition interlock device may be required for longer than the suspension period.

What Happens if I Fail to Complete or Refuse to Submit to a DWI Test in Missouri?

You will not be exempt from penalties if you refuse to take a breathalyzer or blood alcohol content test. Those who refuse to take the test will have their license suspended for one year.

How Do I Get a Restricted Driving Privilege in Missouri?

This option is only available for first offenders. To qualify, offenders must install an ignition interlock device and meet other criteria, including:

• Complete and submit their request for an Immediate 90-day Restricted Driving Privilege form, within 15 days of being notified that driving privileges are suspended or revoked
• Install and file proof of installation for an IID approved by the state
• File proof of SR-22 insurance
• Complete all other court requirements

How Do I Get a Limited Driving Privilege in Missouri?

Repeat offenders are not eligible for the Restricted Driving Privilege option, but in some cases, they may apply for a Limited Driving Privilege. Sometimes this is referred to as a hardship license. There is no option for a limited commercial driver’s license. To qualify, offenders must either submit an application to the Department of Revenue or petition the court.

Offenders without a previous offense in the last five or 10 years can submit an application to the Department of Revenue, and they also need to:

• Complete the Application for Limited Driving Privilege Form
• Obtain and show proof of SR-22 insurance coverage
• If there is more than one offense or their license is currently revoked, offenders must provide proof of IID installation
• Must keep a state-approved ignition interlock device installed during the entire time they have the LDP

Offenders with an active five or 10-year denial on their record cannot simply apply for a Limited Driving Privilege - they must petition the circuit court in the county where they live or work. Other things the offender must do to qualify, include:

• Pay a filing fee and court costs associated with the petition
• Pay any legal fees if necessary
• Submit a form proving SR-22 insurance coverage
• If there is more than one alcohol offense or an active Chemical Revocation on the driver’s record, they must submit proof that an IID has been installed in any vehicle the offender operates.

If the court approves the petition, the offender will receive an Order Granting Limited Driving Privilege.
