Modifies provisions relating to the issuance and renewal of license plates and placards for persons with disabilities

HB 127 modifies Missouri's rules for disability license plates and placards. It expands who can certify a person's disability (including nurse practitioners, physical therapists, and other licensed providers) and clarifies the medical criteria for "physically disabled" status, such as needing assistive devices or having specific respiratory or cardiac conditions. The bill requires certification documents to include diagnosis details, provider license numbers, and clear expiration dates (up to 180 days for temporary placards). It directly affects Missouri residents with qualifying disabilities seeking these plates/placards, ensuring consistent medical verification and preventing misuse.
