Creates new provisions relating to persons with impaired or limited ability to communicate with law enforcement

SB 1658, known as "Mason's Law," allows Missouri residents with a health condition or disability that impairs communication with police to request a special designation on their vehicle license plate. To qualify, applicants (or their family members) must obtain certification from a physician or psychologist confirming the condition will last at least five years. Approved designations will be shared with law enforcement via the Missouri Uniform Law Enforcement System (MULES), alerting officers to potential communication needs during interactions. The program requires renewal every five years and mandates that law enforcement agencies receive training on the designation.
