What Act 233 changed
Louisiana’s official approval table records Act 233, originating as HB 855, as signed on May 31, 2022 and effective on August 1, 2022. This is a historical account reviewed on October 14, 2026.
The act amended R.S. 32:361.2(A)(3)(c). It preserved the normal three-year review provision, unless the department determines otherwise, and added an ownership-duration provision for an exemption granted to a person diagnosed with light-sensitive porphyria. The official act summary describes the same narrow change.

Ownership duration is not automatic approval
The ownership-duration language remains in the current statute. It concerns an exemption already granted; it does not itself diagnose a person or eliminate the medical-exemption process. The statute still provides for a clinician-signed affidavit, case-by-case departmental review and possible administrative cancellation in specified circumstances.
The affidavit identifies the vehicle. When a covered vehicle is sold or traded, the statute places responsibility for removing the tint on the person accepting the vehicle unless the new owner has applied for and received an exemption. The 2022 change should therefore not be described as a transferable lifetime permission.

Separate windshield conditions remain
The act’s amendment was confined to exemption duration. Current law separately addresses windshield coverage below the top six inches: it requires specific authorization by the optometrist or physician for a patient diagnosed with light-sensitive porphyria.
