Bill Summary · HB 2352

Purpose and intent

  • Missouri House Bill 2352 aims to require ignition interlock devices (IIDs) for all individuals who are found guilty of an intoxication-related traffic offense.
  • The bill updates current law so that every intoxication-related offense, not just first offenses, triggers the IID requirement.

Key provisions

  • IID requirement for all intoxication-related offenses: Any person found guilty of an intoxication-related traffic offense (as defined in section 577.001) must have a functioning, certified ignition interlock device installed in their vehicle.
  • Minimum installation duration: The IID must be installed for at least six months from the date of reinstatement of the person’s driver’s license.
  • Limited driving privileges: For individuals eligible for a limited driving privilege under section 302.309, the IID must be installed on all vehicles operated by the person as a condition of the privilege, with some exceptions as provided in section 302.441.
  • Additional compliance: The IID requirement operates in addition to any other existing ignition interlock installation and maintenance requirements under chapters 302 and 577.
  • Penalties and enforcement: Individuals required to use an IID must comply with the device obligations and penalties applicable under section 577.599.

Who is affected

  • Drivers convicted of intoxication-related traffic offenses in Missouri.
  • Individuals seeking or granted limited driving privileges after conviction, who would be required to have IIDs in all vehicles they operate as a condition of those privileges.

Procedural and timeline aspects

  • Legislative status: Referred to Emerging Issues (H) as of May 15, 2026; previously progressed through readings in January 2026.
  • Effective scope: If enacted, the IID requirement would apply to all intoxication-related offenses, with implementation rules embedded in the revised section 302.440 and related references to 302.309 (limited driving privileges) and 302.441.
  • Start point: The six-month IID period begins from the date of reinstatement of the driver’s license after conviction.

Practical impact considerations

  • Road safety: The measure strengthens penalties for intoxication-related offenses by broadening IID use, potentially reducing repeat offenses.
  • Privacy and cost: Drivers convicted of offenses would incur IID installation, maintenance, and monitoring costs for at least six months, and possibly longer on limited-privilege vehicles.
  • Administrative: Courts and licensing authorities would apply the IID requirement uniformly to all intoxication-related offenses, increasing monitoring and compliance tasks.

Note: The bill text indicates a shift from “first offense” (current law) to “any offense,” expanding the IID mandate to all intoxication-related offenses.
