The bill amends the Michigan Vehicle Code to enhance the definitions and requirements concerning disabled individuals and their parking privileges. It broadens the definition of "disabled person" to include additional healthcare professionals, such as certified nurse practitioners and occupational therapists, who can certify disabilities. The bill also clarifies the criteria for determining disabilities, specifying certain medical conditions and mobility limitations. Language modifications throughout the sections aim to improve clarity by replacing terms like "a person" with "an individual."

Additionally, the bill establishes new regulations for the issuance and management of windshield placards and free parking stickers for disabled individuals. Key changes include the requirement for placards to display the first letter and last three digits of the disabled person's driver's license or state ID number, and it allows occupational therapists to sign applications. Stricter penalties for misuse of special registration plates and tabs are introduced, classifying such misuse as a misdemeanor. The bill also mandates that individuals receive notice and an opportunity to be heard before any cancellation or revocation of their placard or sticker, while streamlining the language by removing the definition of "disabled person" from certain sections.
