Mississippi law permits passenger‑side windows to be tinted to a minimum of 30% visible light transmission (VLT), while the driver’s side, front‑side, and windshield must allow at least 70% VLT. Any tint darker than these limits is illegal for passenger vehicles, and violations can result in fines, vehicle inspection failures, and possible citation at traffic stops.
Mississippi Tint Law Basics
The state’s window‑tint regulations are codified in Mississippi Code § 63‑7‑3 and enforced by the Mississippi Department of Public Safety (DPS). The purpose of the law is to ensure that law‑enforcement officers can see inside the vehicle during traffic stops and that drivers maintain adequate visibility in various weather conditions.
Allowed VLT Percentages
- Front windshield: Must be clear; any non‑reflective tint is limited to 5% VLT and must not impair driver visibility.
- Front side windows (driver’s side and passenger’s side): Minimum 70% VLT (i.e., no more than 30% tint).
- Rear side windows and rear window: Minimum 30% VLT (i.e., up to 70% tint is permissible).
These percentages are measured with a certified light‑transmission meter. A tint that blocks more light than allowed is considered “too dark.”
Exceptions and Medical Exemptions
Mississippi provides a medical exemption for drivers who require darker tint due to a diagnosed condition such as lupus or photosensitivity. The driver must obtain a physician’s statement and submit it to the DPS to receive a special permit. The exemption does not apply to commercial vehicles or motorcycles.
Enforcement and Penalties
If a police officer determines a vehicle’s tint exceeds legal limits, the driver receives a citation and may be required to remove the illegal film. First‑offense fines range from $150 to $200, with additional court costs. Repeat offenses can lead to higher penalties and may affect vehicle registration renewal until compliance is demonstrated.
How to Verify Compliance
- Purchase a calibrated tint meter or have a professional perform the test.
- Check the manufacturer’s specifications for VLT ratings before installation.
- Request a compliance certificate from the installer; reputable shops provide documentation.
- Schedule a pre‑emptive inspection at a local DPS office if you are unsure about the tint’s legality.
What is the legal VLT for the driver’s side window?
The driver’s side front window must allow at least 70% VLT, meaning the tint cannot block more than 30% of visible light.
Can I have a completely black rear window?
No. Mississippi law requires the rear windows to transmit at least 30% VLT, so a fully blacked‑out rear window is illegal.
Do window stickers affect the VLT calculation?
Stickers and decals are not counted in the VLT measurement; only the film’s light‑blocking properties are considered.
Are aftermarket tint films always legal if they meet the VLT numbers?
Yes, provided the film is installed correctly and the vehicle passes a DPS inspection. The film’s brand is irrelevant; only the measured VLT matters.
How do I obtain a medical exemption for darker tint?
Obtain a written statement from a licensed physician detailing the medical need, submit the form to the Mississippi DPS, and receive a written exemption that allows you to exceed standard VLT limits for the specified windows.
