Mississippi window tint laws

For a sedan in Mississippi, front side windows must let at least 28% of light through, back side windows at least 28%, and the rear window at least 28%. Lower VLT means darker glass, so those percentages are floors, not targets, and the meter reads the film and the factory glass together. SUVs, vans and trucks are listed separately: front side 28%, back side no VLT limit, rear no VLT limit.

No, not on the front side windows. Mississippi requires at least 28% VLT there and 20% is darker than that, before you even account for the factory glass, which makes the reading darker still. The back side windows have a 28% floor, so 20% is too dark there too.

Mississippi's rule for the windshield: No tinted film, glazing material, or darkening material of any kind on the windshield, except material designed to replace or provide a sun shield in the uppermost area as authorized to be installed by vehicle manufacturers under federal law

What the source says: Yes (§63-7-59(4)): a person diagnosed by a physician licensed to practice medicine in Mississippi as having a physical condition or disease seriously aggravated by minimum exposure to sunlight may tint beyond the limit on a vehicle they own, operate, or regularly ride in. The vehicle must prominently display on the dashboard a certificate of medical exemption on a form prepared by the Commissioner of Public Safety and signed by the person on whose behalf it is issued. The certificate is issued free of charge through county tax collectors' offices; the applicant must present (a) an affidavit signed personally by the applicant and signed and attested by a physician stating the qualifying condition, and (b) proof of vehicle ownership, or a signed affidavit from the owner of a vehicle operated for the applicant's use. PHYSICIAN ONLY: HB 654 (2026) would have added Mississippi-licensed optometrists, but it died on the House calendar 02/12/2026, so optometrist documentation is NOT currently sufficient. Confirm the current process with the agency named before you have film installed.

Required. §63-7-59(2)(a) makes it unlawful to drive a tinted vehicle unless the windshield carries a DPS-issued label certifying that all the windows have a light transmittance of 28% or more (or the operator holds a medical exemption certificate). DPS issues labels to official tint inspection stations; the label goes on the LOWER LEFT corner of the windshield, must be legible from outside, and shows the label registration number and a certification of compliance. Labels are pressure-sensitive, self-destructive on removal, and no larger than 1 inch square. The station must test the window's light transmittance before affixing the label, using DPS-approved and at-least-annually-certified methods or devices, and charges a $5 fee ($2 retained by the station, $3 remitted to DPS). No fee may be charged unless a test is actually performed.
