Missouri (MO) - State Requirements for Ignition Interlock Devices

The Missouri Ignition Interlock Program

Anyone who is caught operating a vehicle with a blood alcohol content above the legal limit risks fines, possible jail time, and license suspension. The legal limit in Missouri is .08 percent. Some offenders may be able to get a Restricted Driver's License if they install an interlock device.

Missouri requires convicted DWI offenders to obtain an ignition interlock device from a state-approved interlock provider to regain driving privileges. In some cases, the offender may need to keep the IID for longer than the license suspension period. The state will provide a list of approved providers - Intoxalock is an approved provider in Missouri.

 

What Happens if I Get a DWI in Missouri?

Missouri employs a variety of administrative and financial penalties to DWI offenders. The penalties increase if there is a prior offense, or depending on the circumstances of the incident. For example, if a minor is in the car at the time of the offense, the penalties may increase.

First DWI Offense

  • Up to six months in jail
  • Fines up to $1,000
  • License suspended for 30 days, plus an additional 60 days of license restrictions
  • IID Missouri approves required to obtain Restricted Driver’s License

Second DWI Offense

  • Up to one year in jail
  • Fines up to $2,000
  • License revoked or up to five years
  • Install interlock approved by Missouri, for six months or more in order to regain driving privileges

Third DWI Offense

  • Up to four years in jail
  • Fines up to $10,000
  • License revoked for up to 10 years
  • Ignition interlock device required for at least six months, and to regain driving privileges

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
