South Carolina Window Tint Laws: VLT Limits & Fines

Key takeaways
- South Carolina requires a 27% VLT minimum on regulated windows, but the rule for how dark the back windows can go changes depending on whether you drive a car or an SUV, truck, or van.
- State law regulates reflectivity, tint color, and a required compliance sticker separately from the darkness percentage itself.
- A first tint violation counts as a misdemeanor, carries a fine of up to $200, and can end with an officer telling you to remove the film on the spot.
- Drivers with a qualifying medical condition can apply through the SC DMV for a certificate that allows darker tint than the standard limit.
Quick answer: how dark can you legally tint in South Carolina?
South Carolina law sets a 27% VLT (visible light transmission) floor on regulated windows. In plain terms, at least 27% of outside light has to pass through the glass on the windows the law covers.
That single number does not tell the whole story, though. Where that 27% rule applies, and where it does not, depends entirely on what you drive. Passenger cars follow one set of rules. SUVs, trucks, and vans follow another. We break down both below, along with the windshield, reflectivity, and color rules that trip up a lot of drivers who only checked the darkness percentage.
VLT limits by vehicle type
Passenger cars (sedans, coupes)
If you drive a sedan or coupe, South Carolina holds every window to the same standard:
- Front side windows: Must allow more than 27% of light in.
- Back side windows: Must allow more than 27% of light in.
- Rear window: Must allow more than 27% of light in.
SUVs, trucks, and vans (MPVs)
Multi-purpose vehicles get more flexibility in the back:
- Front side windows: Must allow more than 27% of light in, same as a sedan.
- Back side windows and rear window: South Carolina allows any darkness level here, including tint as dark as you want.
| Window | Passenger cars | SUVs, trucks & vans |
|---|---|---|
| Front side windows | More than 27% VLT | More than 27% VLT |
| Back side windows | More than 27% VLT | Any darkness allowed |
| Rear window | More than 27% VLT | Any darkness allowed |
That front-window rule holds no matter what you drive. It is the one limit every South Carolina driver needs to know before booking an appointment.
Windshield tint rules
South Carolina treats the windshield differently from every other window. Non-reflective tint is legal, but only above the manufacturer's AS-1 line, typically the top 5 to 6 inches of the glass. Anything below that line on the windshield needs to stay clear.
General rules and restrictions
Getting the darkness percentage right solves only part of the equation. A few other rules apply across every vehicle type.
Reflectivity limit
Tint film cannot reflect more than 20% of light, and it cannot give the glass a mirrored appearance. A tint that looks like a mirror from the outside, even if it technically meets the VLT number, can still get you pulled over.
Prohibited colors
South Carolina bans red, amber, and yellow tint on the front windows and windshield. Stick to standard shades, and confirm the color with your installer before they apply anything.
Certification sticker
The state requires a compliance sticker between the film and the glass on every tinted window. This sticker identifies the tint as legal and gives an officer a quick way to confirm compliance without pulling out a light meter. A licensed installer applies this automatically, one more reason to skip the DIY kit.
Dual side mirrors
If you tint your rear window, South Carolina requires both side mirrors on the vehicle. This one catches drivers off guard, especially on older trucks or vans that came from the factory with a single mirror.
Medical exemptions
Drivers with a qualifying medical condition can apply through the South Carolina DMV using Form MED-1 for a certificate that allows tint darker than the standard limit. Talk to your doctor first. They need to complete part of the form before the DMV will process it.
Penalties and fines
South Carolina treats tint violations under SC Code §56-5-5015 as a misdemeanor, not a simple ticket you pay and forget. A first offense carries a fine of up to $200, and the officer can require you to remove the illegal film before you drive away legally. Repeat violations typically cost more and draw closer scrutiny at every stop after that.
Confirm the specific fine amount and current statute language directly with the South Carolina DMV or a local law enforcement agency, since fine structures and enforcement practices can shift over time.
South Carolina tint law FAQs
Is 5% tint legal in South Carolina?
No, not on the front windows of a passenger car. Five percent tint blocks too much light to meet the 27% VLT minimum that applies to front windows on every vehicle type. On the back windows or rear window of an SUV, truck, or van, 5% tint is legal because those windows have no darkness ceiling.
Is 20% tint legal on a sedan?
No. Twenty percent VLT falls below the 27% minimum, so it does not meet the legal standard on any window of a passenger car.
Is 35% tint legal on my SUV's rear window?
Yes. SUVs, trucks, and vans can run any darkness level on the back side windows and rear window, so 35% tint is legal there. The front side windows still need to clear 27% VLT.
What's the darkest legal tint for a truck?
On the front side windows, 27% VLT is the darkest legal option. On the back side windows and rear window, there is no legal darkness limit.
Do I need a sticker if I only tint one window?
Yes. South Carolina requires a compliance sticker on every tinted window, not just the darkest one or the first one installed.
South Carolina tint laws
South Carolina's tint rules come down to a few numbers and a few restrictions: 27% VLT on regulated windows, no more than 20% reflectivity, no red, amber, or yellow tint up front, and a compliance sticker on every window you tint. Get those right, and you avoid the fine, the roadside hassle, and the cost of redoing the work.
Have a professional installer confirm the legal tint percentage for your specific vehicle before any film goes on the glass, rather than guessing based on what looks good in a photo online.
