SB 1658 - This act establishes "Mason's Law". At the time of motor vehicle registration, a resident of this state with a health condition or disability that limits or impairs the ability to effectively communicate with law enforcement may apply to the Department of Revenue for a designation that shall be associated with the person's motor vehicle license plate number and be available to law enforcement. Upon approval of the application, the Department shall notify the Missouri State Highway Patrol and the Highway Patrol shall prepare an entry in the Missouri Uniform Law Enforcement System (MULES). Such entry shall remain active for five years, unless the applicant requests such designation be removed from the system. Upon expiration of the five year period, a renewal form may be filed with the Department to renew the designation. This act is identical to SB 1676 (2026), SS#2/SCS/HCS/HB 1840 (2026), and HB 3492 (2026), and substantially similar to HB 3175 (2026) and HS/HCS/HBs 3068 & 3049. TAYLOR MIDDLETON

Missouri bill requiring law enforcement to accommodate individuals with communication disabilities during interactions to improve safety and prevent misunderstandings.

Second Read and Referred S Transportation, Infrastructure and Public Safety Committee

Legislative bill overview

SB 1658 establishes new legal protections and procedures for individuals with speech, hearing, developmental, or cognitive disabilities during law enforcement interactions. The bill requires officers to accommodate communication needs and creates standards for how police must engage with people who have difficulty communicating verbally or understanding spoken instructions.

Why is this important

People with disabilities are disproportionately involved in negative police encounters, including higher rates of arrest and use of force. Without clear communication protocols, misunderstandings can escalate situations dangerously. This bill aims to reduce those risks by ensuring officers have tools and requirements to interact safely with vulnerable populations.

Potential points of contention

Implementation costs: Law enforcement agencies may face expenses for training officers, acquiring communication aids, and potentially hiring trained intermediaries during interactions

Officer discretion concerns: The bill's effectiveness depends on police judgment about whether someone has an impairment; unclear standards could lead to inconsistent application

Response time trade-offs: Accommodating alternative communication methods may take longer, raising questions about how this balances with urgent situations or officer safety protocols
