Motor vehicle tinted window; authorize those diagnosed with certain condition by optometrist licensed in the state to drive with.

HB 654 amends Mississippi's vehicle tinting law to allow optometrists licensed in the state to certify medical exemptions for drivers with light-sensitive conditions. It directly affects individuals diagnosed by an optometrist with conditions aggravated by sunlight exposure, enabling them to legally use tinted windows that would otherwise violate state law. The key provision expands the current exemption process - previously limited to physicians - to include optometrists, who can now provide the required medical documentation. This change streamlines access to exemptions without altering the existing requirements for certification, vehicle labeling, or light transmittance standards. The bill does not change the exemption criteria or the need for a dashboard certificate issued by county tax collectors.
