South Carolina Window Tint Law 2026: what's legal, what's not, and what actually gets you pulled over.
The short version: SC law caps front side windows at 27% VLT on every vehicle. On SUVs and trucks, rear sides and back glass can be as dark as you want. This guide covers the full law — reflectivity rules, medical exemption, fines, and what shade we actually recommend for Charleston's heat and UV.
VLT limits by vehicle + window.
| Window | Passenger car (sedan, coupe) | SUV / Truck / Van |
|---|---|---|
Windshield The AS-1 line is the short horizontal mark etched on the glass near the top. No tint below it except a medical-exempt clear UV strip. | AS-1 line only · non-reflective strip above the AS-1 line | AS-1 line only · non-reflective strip above the AS-1 line |
Front side windows (driver & passenger) The 27% rule applies identically across all vehicle types in SC — no exception for SUVs or trucks on the front sides. | 27% VLT minimum | 27% VLT minimum |
Rear side windows This is the biggest split in the law. SUVs, trucks, and vans can go as dark as they want on the rear sides — including blackout. Passenger cars are capped at 27% VLT. | 27% VLT minimum | Any darkness permitted |
Rear window (back glass) Same split as rear side windows. If a sedan or coupe's rear window goes below 27%, dual outside mirrors are required (left and right). | 27% VLT minimum | Any darkness permitted |
SC Code §56-5-5015 (tint limits) and §56-5-5020 (reflectivity and color). Measurement tolerance: ±3% on the VLT meter reading at the window.
VLT percentages translated.
Nearly clear. Most factory-tinted SUV rear glass is around 20%, but factory-clear front windows read around 70–80%. Universally legal in every state.
Noticeable tint, still reads as daylight from outside. Solid heat/UV performance with minimal darkness. Always legal in SC.
The most-requested shade in the Lowcountry. Reads as a gentle privacy tint; 35% falls within the SC ±3% variance range (24–30% measured), so properly-installed 35% is legal on every window of every vehicle.
SC's minimum VLT for front side windows and — on passenger cars — rear sides and back glass. This is the darkest you can legally go on a sedan's fronts.
Typical factory tint on SUV and truck rear windows. Illegal on any SC passenger-car front side window. Legal on SUV/truck rears.
Illegal on any SC front side window. Legal on SUV, truck, and van rear sides and back glass.
Illegal on any SC front side window. Legal on SUV/truck/van rear glass. Often requested — we install it on qualifying vehicles with a signed acknowledgment that the fronts stay at 27%+.
Going darker than 27% legally.
SC offers a medical exemption for drivers with diagnosed conditions that require reduced UV or visible-light exposure — lupus, xeroderma pigmentosum, severe photosensitivity, and similar. The process is simple:
- Physician completes SC DMV Form MED-1 — a one-page form certifying the medical need for reduced light exposure.
- Submit the form to your local DMV office with a $1 fee.
- DMV issues an exemption certificate. Keep it in the vehicle and present it if pulled over.
The exemption lets you go darker on windows that would otherwise be restricted, including the windshield. The film still has to meet reflectivity and color rules, and you'll need to present the certificate at inspection.
Fines and the real-world reality.
Per SC Code §56-5-5015. Typically paired with a warning to bring the vehicle into compliance within a set window (usually 30 days).
Officers at the ticket can order illegal film removed as a condition of continuing to drive the vehicle.
Fleets running illegal front-side tint face fines per vehicle at inspection — adds up fast on a 10-truck operation.
In the Charleston metro, tint tickets are most commonly issued during other stops — traffic infractions, expired tags — rather than as primary stops. That said, tickets do get written, especially on front windows significantly below 27% VLT. The window shade enforcement mostly kicks in on vehicles that look noticeably blacked-out up front.
The shade we install most often — and why.
Sedans and coupes — 35% all-around. It's the most-requested legal shade in Charleston. At ±3% variance you measure around 32%, safely above the 27% floor. Reads as a light privacy tint, doesn't affect night visibility, and with a proper ceramic film (LuxeGuard, 3M Ceramic IR) rejects 80–99% of infrared heat depending on tier — which is what actually cools the cabin.
SUVs and trucks — 35% fronts, 20% rears. The legal split lets you run factory-privacy darkness (20%) on the back and a gentler 35% up front for visibility. Most popular combination we install.
Limo tint (5%) on SUV / truck rear glass. Legal on qualifying vehicles. We install it with a signed acknowledgment that the front sides stay at 27% or lighter. If you own a sedan and want the car blacked-out-looking from outside, 5% on the fronts is not an option in SC without a medical exemption.
Ceramic films only. Reflectivity law caps tint at 20% reflective. Cheap metalized films can exceed that at certain shades — ceramic films (including every film we install) are well under the cap. Ceramic also performs better: more heat rejection at the same VLT, no GPS/cell signal interference, and doesn't fade purple like dyed-only films at year 2–3.
SC tint law — rapid-fire answers.
What is the legal window tint limit in South Carolina?
On passenger cars (sedans, coupes), all tinted windows must allow at least 27% VLT (Visible Light Transmission). On SUVs, trucks, and vans, the 27% minimum applies only to front side windows — rear sides and back glass can be as dark as you want. Windshields in every vehicle are limited to a non-reflective strip of tint above the AS-1 line.
Is 35% tint legal in SC?
Yes. 35% VLT is legal on every window of every vehicle in South Carolina. It's the most-requested shade we install and falls comfortably within the state's ±3% tint-meter variance. Your 35% film will measure between 32–38% at the window, well clear of the 27% legal floor.
Is 20% tint legal in SC?
20% is legal on the rear side windows and back glass of SUVs, trucks, and vans — but illegal on any passenger-car front side window, and illegal on the front sides of an SUV or truck. For a sedan, the darkest legal shade on the fronts is 27%.
Is 5% tint (limo tint) legal in SC?
5% is illegal on any front side window in South Carolina, regardless of vehicle type. It's legal on the rear sides and back glass of SUVs, trucks, and vans. We install it for qualifying vehicles with a signed customer acknowledgment confirming the fronts remain at 27% or lighter.
Can I get a medical exemption for darker tint in SC?
Yes. SC offers a medical exemption for drivers with conditions that require reduced UV or visible-light exposure (lupus, xeroderma pigmentosum, photosensitivity, and similar diagnoses). The process: get your physician to complete the SC DMV Form MED-1; submit it to the DMV along with a $1 fee; DMV issues a medical tint exemption certificate to keep in the vehicle. The exemption allows darker tint on windows that would otherwise be restricted.
What happens if I get pulled over for illegal tint?
First offense is a $200 fine under SC Code §56-5-5015. The officer may require you to bring the vehicle into compliance (typically removing the illegal film) within a set time. Continued violations stack additional fines and can include a court-ordered removal of the film.
Does tint variance (3%) mean I can run 25% tint?
No — the variance is on the meter, not the spec. SC allows ±3% measurement tolerance: a certified 27% film might read 24–30% at the window, and the officer's reading is considered legal within that range. But you can't intentionally order 25% tint and claim the 3% variance. The film's certified VLT has to be 27% or higher.
Does SC limit tint reflectivity?
Yes — tint cannot be more than 20% reflective. This rules out high-reflectivity mirrored tints on front side windows. Most ceramic films (including LuxeGuard and 3M Ceramic IR) are well under the reflectivity cap — metalized films are where this becomes an issue.
Are red, amber, or yellow tints legal in SC?
No. SC prohibits red, amber, or yellow tint on the windshield or front side windows. Factory UV-tint layers on OEM glass are exempt. Aftermarket colored films for the front glass of the vehicle are not legal.
Does SC require certification labels on tinted windows?
Yes. Each tinted window must be labeled with the manufacturer's certification sticker showing the VLT and meeting SC regulations. Installers (ourselves included) are required to apply these at install. Missing labels during an inspection put the installer on the hook, not just the owner.
Can I tint my windshield in SC?
Only the strip above the AS-1 line. Look for the short horizontal mark etched on your windshield near the top — that's the AS-1 line. The area above it can be tinted (typically a 5-6 inch non-reflective sun strip). Everything below it must stay factory-clear, except for a medical-exempt clear UV film at full windshield coverage.
How is 'VLT' measured, and how do I know what my tint actually reads?
VLT (Visible Light Transmission) is measured with a handheld meter that clamps onto the window glass. The reading accounts for the film + the factory glass together — so the final measured VLT is always lower than the film's rated VLT because factory glass already blocks some light. A 35% film on factory glass typically reads around 30–32% at the window.
Ceramic tint at the legal limit — installed right.
3M Ceramic IR, LuxeGuard Nano, and LuxeGuard Pro HD — installed at the legal limit, with certification labels per SC law and lifetime film warranty.
