MO HB3175

"Mason's Law" creates a voluntary program beginning January 1, 2027, allowing Missouri residents with health conditions or disabilities that impair communication with law enforcement to register a designation linked to their license plate number in the MULES law enforcement database.

Applicants must submit a form signed by a licensed physician or psychologist certifying that the applicant, their child, parent, or spouse has a physical or mental health condition impairing communication that will last at least five years.

The Department of Revenue processes applications and notifies the Missouri State Highway Patrol, which enters the designation into MULES where it remains active for five years unless the applicant requests removal.

Renewal after five years requires a new certification from a licensed physician or psychologist confirming the continued communication impairment.

The Department of Public Safety must issue guidance and education materials to all law enforcement agencies statewide to promote awareness of the designation system.
