How to Check Whether Your Vehicle Tint Complies in South Carolina

South Carolina tint law at a glance

Important legal-source notice: This guide explains a third-party reproduction labeled as the 2025 text of South Carolina Code §56-5-5015. The supplied evidence does not include a live official South Carolina Code page or current agency guidance. Therefore, this article cannot confirm that every requirement remains unchanged in 2026 and should not be treated as a definitive compliance determination or legal advice. Verify the current official code and applicable agency guidance before installing, replacing, or removing tint.

Under the reproduced 2025 text, regulated aftermarket tint on side windows generally must transmit at least 27% of visible light through the factory glass and film together. Exactly 27% satisfies an “at least 27%” standard, although targeting the boundary leaves no practical margin for a finished measurement below it. The applicable rule also depends on the window’s position and the vehicle’s legal classification.¹

For the windshield, the reproduced statute permits a nonreflective sunscreening device only along the top and above the visible AS-1 line. The material cannot be red, yellow, or amber. If the AS-1 line is not visible, the reproduced text says that no sunscreening device may be applied to the windshield; it does not provide a generic five-inch alternative.¹

Rear-window treatment cannot be reduced to a simple “car versus SUV” rule. The reproduced provision distinguishes pickup trucks from multipurpose passenger vehicles and several other vehicle classes. In particular, a pickup should not assume that it receives the same behind-the-driver treatment as a vehicle legally classified as a multipurpose passenger vehicle.¹

A practical compliance review should cover:

• The vehicle’s legal classification
• Every window receiving aftermarket material
• The completed glass-and-film visible light transmission
• The windshield’s visible AS-1 boundary
• Tint color and reflectivity
• Outside-mirror requirements
• A compliance certificate on every affected window
• Any medical-exemption documentation

Those checks describe the reproduced 2025 framework, not independently verified current law.¹

What 27% VLT means—and why the film label is not the final result

Visible light transmission, or VLT, is the percentage of visible light that passes through a window. A higher percentage admits more visible light and produces a lighter result. A lower percentage admits less visible light and produces a darker result.

Accordingly, 27% VLT does not mean 27% darkness. It means that approximately 27% of the measured visible light passes through the window.

The critical point in the reproduced South Carolina provision is that the threshold applies to the combined light transmission of the aftermarket sunscreening device and the factory- or manufacturer-installed material. The film’s advertised VLT is not, by itself, the completed window’s legal measurement.¹

For planning purposes, combined VLT can be estimated as:

Approximate combined VLT = glass VLT × film VLT

Convert both percentages to decimals, multiply them, and convert the result back to a percentage.

Illustration 1: an estimated result above 27%

• Glass VLT: 80%, or 0.80
• Film VLT: 35%, or 0.35
• Calculation: 0.80 × 0.35 = 0.28
• Approximate completed-window VLT: 28%

An estimated 28% result is above the reproduced statute’s 27% minimum.¹

Illustration 2: an estimated result below 27%

• Glass VLT: 80%, or 0.80
• Film VLT: 30%, or 0.30
• Calculation: 0.80 × 0.30 = 0.24
• Approximate completed-window VLT: 24%

An estimated 24% result falls below that minimum.¹

The same calculation shows why film labeled 27% does not guarantee a completed reading of 27%:

0.80 × 0.27 = 0.216

In that illustration, 27% film over glass measured at 80% would produce an estimated combined VLT of 21.6%, below the reproduced 27% standard.¹

Treat this formula as a planning tool, not a substitute for measurement. Ask the installer to measure the untreated glass, calculate the expected combined result, and test each regulated window after installation.

Photometers are commonly used to measure light transmission through automotive glass. That is general measurement context, not evidence of a particular South Carolina officer’s equipment, testing procedure, calibration practice, or enforcement threshold. The supplied evidence does not establish a statewide measurement tolerance, so an installation should not be designed around an assumed grace percentage.²

Window-by-window requirements under the reproduced statute

The following table summarizes the supplied third-party reproduction. Vehicle-class provisions can alter the treatment of windows behind the driver, and current official law has not been independently verified for this article.

Window location	Practical rule in the reproduced 2025 text
Windshield	A sunscreening device must be nonreflective, cannot be red, yellow, or amber, and may be used only above the visible AS-1 line. If the AS-1 line is not visible, no sunscreening device may be applied. The text provides no generic five-inch fallback.1
Windows immediately beside the driver	One aftermarket sunscreening device may be installed. It must be nonreflective, and the glass and device together must transmit at least 27% of visible light.1
Side windows behind the driver	The general rule requires nonreflective material and at least 27% combined transmission before the statute’s vehicle-class provisions are considered.1
Rear-most window	Under the provision applying from January 1, 1993, the device generally must be nonreflective and provide at least 27% combined transmission. A right and left outside rearview mirror are required when a sunscreening device is used there, subject to the relevant vehicle-class provisions.1

The windshield rule turns on the manufacturer’s visible AS-1 line, not a tint shop’s customary strip depth or a general measurement from the roof. Under the reproduced text, a driver cannot substitute an assumed five-inch strip when the AS-1 line is not visible.¹

For the windows immediately to the driver’s right and left, evaluate the completed glass-and-film combination. A product labeled 35% may produce different completed results depending on the underlying glass. The product label alone does not establish compliance with the combined-transmission rule.¹

For windows behind the driver, begin with the general nonreflective and at-least-27% rule, then determine whether the vehicle falls into one of the legal classes for which the reproduced provision does not apply the behind-the-driver transmission requirement.¹

The reproduced section also says that its light-transmittance provisions do not apply when no after-factory sunscreening device has been added to the window surface. That distinction concerns whether aftermarket material is present; it does not establish that every dark-looking window is exempt. Film added over factory glass brings the aftermarket-device provisions into the analysis.¹

Cars, pickups, SUVs, and vans: why legal classification matters

Consumer tint charts commonly divide vehicles into “cars” and “SUVs or vans.” The reproduced South Carolina provision uses more specific categories, including pickup trucks, other trucks, buses, trailers, mobile homes, multipurpose passenger vehicles, and recreational vehicles.¹

The reproduced text applies the behind-the-driver light-transmission requirements to pickup trucks. It does not apply those requirements to the listed behind-driver windows of other trucks, buses, trailers, mobile homes, multipurpose passenger vehicles, and recreational vehicles.¹

This distinction means that “all trucks can use any rear tint” is not a safe reading. A pickup is treated differently from the separate category of other trucks. Likewise, a vehicle being advertised as an SUV, crossover, or van does not by itself establish that it is a multipurpose passenger vehicle for purposes of the statute.

The supplied evidence does not include the current official definitions governing these classes or establish which field on a title, registration document, manufacturer label, or other record conclusively controls the analysis. Vehicle records and manufacturer documentation may help, but owners should not assume that a casual body-style description resolves the legal category.

Consider three bounded scenarios:

1. Passenger sedan: Under the reproduced framework, plan around at least 27% combined VLT on regulated aftermarket-tinted side windows and rear-most glass. Also check nonreflectivity, color, mirrors, and certificates.¹

2. Pickup truck: Do not treat the rear side or rear-most windows as automatically unrestricted. The reproduced provision applies its behind-the-driver transmission requirements to pickups.¹

3. Legally classified multipurpose passenger vehicle: It may fall within the stated exception from the behind-the-driver light-transmission requirements. That exception does not erase unrelated requirements affecting the windshield, front side windows, certificates, colors, or reflective material.¹

If the classification remains uncertain, consult current official vehicle records and ask the appropriate South Carolina authority how the statutory category applies before selecting rear-window darkness. This is particularly important for crossovers, passenger-oriented vans, commercial vans, and vehicles that may fit more than one everyday description.

Reflectivity, prohibited colors, mirrors, and window certificates

VLT is only one part of the reproduced compliance framework. A window may admit enough visible light and still fail another requirement.

Nonreflective material

The reproduced statute requires qualifying aftermarket sunscreening devices to be nonreflective. The supplied text does not specify a numerical reflectivity percentage, so a percentage used by another state or an unsupported commercial chart should not be substituted for the statutory wording.¹

Ask the installer to identify whether the selected product is reflective or mirror-like and whether it is intended to meet South Carolina’s nonreflective requirement. Heat-control or appearance claims do not independently answer that legal question.

Prohibited colors

The reproduced statute prohibits red, yellow, and amber sunscreening devices.¹

Select film that is not sold or identified as one of those colors. If a film has a pronounced hue, ask the installer to evaluate how it appears with the vehicle’s existing glass, while recognizing that the statute regulates the sunscreening device itself.

Outside mirrors

When a sunscreening device is used on the rear-most window under the applicable provision, the reproduced statute requires one right and one left outside rearview mirror.¹

The rule should not be shortened to “dark tint requires mirrors.” In the reproduced text, the requirement is tied to using a sunscreening device on the rear-most window, not to an installer’s subjective assessment of whether the tint appears dark.

A certificate on each affected window

Each window carrying an after-factory sunscreening device must have the prescribed compliance certificate in the inside lower-right corner of that window. The reproduced provision does not describe one generic sticker as sufficient for the entire vehicle.¹

The certificate must include:

• The allowed light-transmission percentage
• The installer’s identity
• The installer’s address and telephone number
• The installation date¹

The supplied evidence does not establish a currently approved certificate supplier, installer list, or official certificate format. Obtain current confirmation rather than relying only on a shop’s unsupported assurance.

Before accepting the vehicle, use this installer handoff checklist:

• [ ] Obtain a completed VLT reading for each regulated window.
• [ ] Confirm that the film is nonreflective.
• [ ] Confirm that the device is not red, yellow, or amber.
• [ ] Check both outside mirrors if the rear-most window is tinted.
• [ ] Locate a certificate in the inside lower-right corner of every aftermarket-tinted window.
• [ ] Verify the transmission information, installer identity and contact details, and installation date.
• [ ] Keep the invoice and any recorded meter readings with the vehicle records.

These items reflect the reproduced statute’s measurement, material, mirror, and certificate provisions.¹ Documentation does not make otherwise noncompliant tint lawful, and compliant tint does not eliminate the separate certificate requirement described in the reproduced text.

Medical exemptions, police-canine vehicles, and older tint

The reproduced statute provides a medical exemption when a South Carolina-licensed physician or optometrist signs an affidavit establishing that a person has a physical need for sunscreening material that would otherwise violate the ordinary requirements.¹

The affidavit must remain in the vehicle, must be produced to a law-enforcement officer upon request, and must be updated every two years.¹

The supplied evidence does not establish that any named diagnosis automatically qualifies. It also does not support claims that the exemption requires Form MED-1, a DMV fee, or a separate DMV-issued tint certificate.

A person relying on the reproduced medical-exemption provision should:

1. Obtain an affidavit from a South Carolina-licensed physician or optometrist.
2. Ensure that it establishes the physical need for otherwise noncompliant sunscreening.
3. Keep the current affidavit in the vehicle.
4. Be prepared to produce it to law enforcement upon request.
5. Update it every two years.¹
6. Verify the current official process before relying on the exemption.

Do not assume that a prescription note, diagnosis printout, out-of-state letter, expired affidavit, or installer receipt necessarily satisfies the reproduced statutory requirements.

The reproduced provision also exempts qualifying law-enforcement vehicles regularly used to transport trained police canines.¹

A separate, narrow grandfather provision concerns an original rear-most-window device that complied with the former 20% rule when installed and remains in place. It is not permission to install new 20% rear tint today. Replacing the original device may change whether the grandfather provision applies, so verify the current rule before removing or replacing older material.¹

Violations and penalties for drivers and professional tinters

As general nationwide enforcement context, police may stop a vehicle when its tint appears unlawful, and a photometer is commonly used to measure transmission. The available evidence does not establish a specific South Carolina stop policy, testing procedure, calibration standard, or measurement tolerance.²

Under the reproduced South Carolina provision, applicable owner or operator violations are misdemeanors and, where specified, may carry:

• A fine of up to $200
• Imprisonment for up to 30 days
• Or both¹

“Up to $200” is not a mandatory minimum $200 fine. The precise subsection and alleged conduct matter.

The reproduced statute addresses specified professional-tinter violations separately. Violations involving the certificate or regulated sale-and-installation provisions may carry:

• A fine of at least $1,000 per offense
• Imprisonment for up to 30 days
• Or both¹

These provisions should not be collapsed into one universal penalty. Owners, operators, sellers, and professional installers do not necessarily face identical consequences.

The supplied evidence does not establish that every tint violation:

• Adds driver-license points
• Requires a particular reinspection
• Automatically results in removal
• Uses a statewide measurement tolerance
• Produces the same fine in every case

If you receive a citation, review the statutory section and subsection identified on the ticket and contact the issuing authority about deadlines and procedures. For a disputed classification, medical exemption, grandfathered device, or criminal charge, consider consulting a qualified South Carolina attorney.

A pre-installation compliance checklist and common myths

Use this sequence before paying for an installation or accepting a used vehicle with existing film.

1. Identify the legal vehicle class

Determine whether the vehicle is legally treated as a passenger vehicle, pickup, multipurpose passenger vehicle, or another listed class. Do not rely solely on everyday labels such as “SUV,” “crossover,” “truck,” or “van,” particularly when assessing windows behind the driver.¹

2. Map every window receiving aftermarket material

List the windshield, front side windows, rear side windows, quarter glass, and rear-most window separately. The reproduced requirements vary by window position and, for windows behind the driver, by vehicle class.¹

3. Locate the visible AS-1 line

Inspect the windshield for the manufacturer’s AS-1 marking. Any permitted nonreflective sunscreening material must remain above that line. If the line is not visible, the reproduced text provides no five-inch substitute.¹

4. Select a permitted color and nonreflective finish

Exclude red, yellow, and amber sunscreening devices and choose nonreflective material.¹

5. Estimate combined VLT

Because the reproduced threshold concerns the completed combination, build practical room above 27% rather than designing for a theoretical result exactly at the boundary.¹

6. Measure the completed windows

Request a post-installation reading for every regulated window. Record the result and identify the window tested. “Legal film” is less informative than a completed-window measurement because the reproduced standard addresses combined transmission.¹

7. Confirm the outside mirrors

If the rear-most window receives a sunscreening device, verify that the right and left outside rearview mirrors are present and usable.¹

8. Collect a certificate for every aftermarket-tinted window

Inspect the inside lower-right corner of each affected window. Confirm that the certificate contains the transmission information, installer identity and contact details, and installation date.¹

9. Carry a current medical affidavit when applicable

If relying on the medical exemption, keep the qualifying affidavit in the vehicle, produce it upon request, and update it every two years.¹

Myth versus evidence

Myth: “A roll labeled 27% film is automatically legal.” Evidence: The reproduced statute regulates combined transmission through the glass and film. Film labeled 27% can produce a completed result below 27%.¹

Myth: “Every SUV or truck can use any darkness on the rear windows.” Evidence: The reproduced text uses specific legal categories. Pickup trucks remain subject to the behind-the-driver transmission requirement, while qualifying multipurpose passenger vehicles are among the listed classes treated differently.¹

Myth: “A five-inch windshield strip is allowed when there is no visible AS-1 line.” Evidence: The reproduced text says no sunscreening device may be applied to the windshield when the AS-1 line is not visible.¹

Myth: “Every driver violation carries a minimum $200 fine.” Evidence: The reproduced owner-or-operator penalty is described as a fine of up to $200 where specified, not a universal $200 minimum.¹

Used-vehicle buyers should not assume that tint installed by a former owner complies. Determine whether aftermarket film is present, measure the completed windows, inspect the windshield boundary, establish the vehicle class, check the mirrors, and look for a certificate on each affected window.

Ask an installer to state the expected final combined VLT, not merely the film rating, and request written post-installation readings for each regulated window. If the installer relies on a vehicle-class exception, ask which legal category supports that conclusion and verify it independently.

Frequently asked questions

Is 27% tint legal in South Carolina?

Under the reproduced 2025 text, a regulated completed window measuring exactly 27% combined VLT satisfies the wording “not less than twenty-seven percent.” Film labeled 27% does not guarantee that result because the rule concerns the glass and aftermarket device together.¹

The answer also depends on window position and vehicle classification. This article cannot confirm that the reproduced requirement remains unchanged under current official law.

Can the rear windows of an SUV or van be darker than 27% in South Carolina?

Potentially, but not merely because the vehicle is marketed as an SUV or van. The reproduced provision excludes behind-the-driver windows on multipurpose passenger vehicles and certain other listed classes from the transmission requirement while expressly applying that requirement to pickup trucks.¹

Confirm the vehicle’s legal classification and current official law before selecting rear-window darkness.

Can I use a five-inch windshield tint strip if there is no visible AS-1 line?

Not under the reproduced statutory text. It says that if the AS-1 line is not visible, no sunscreening device may be applied to the windshield. The supplied text contains no generic five-inch fallback.¹

If the marking is difficult to locate, consult the vehicle manufacturer or an appropriate South Carolina authority rather than estimating the boundary.

Does every aftermarket-tinted window need a compliance certificate?

The reproduced statute requires each window with an after-factory sunscreening device to carry the prescribed certificate in that window’s inside lower-right corner. It does not describe one generic vehicle sticker as sufficient.¹

The certificate must include the allowed light transmission, installer identity and contact information, and installation date. The supplied evidence does not establish the currently prescribed format.

How does the South Carolina medical tint exemption work?

The reproduced statute requires an affidavit signed by a South Carolina-licensed physician or optometrist establishing a physical need for otherwise noncompliant sunscreening. The affidavit must remain in the vehicle, be produced to law enforcement upon request, and be updated every two years.¹

The supplied evidence does not establish an automatic list of qualifying diagnoses, Form MED-1, a DMV fee, or a separate DMV-issued tint certificate. Verify the current official procedure before relying on the exemption.

Ultimately, assessing tint under the reproduced 2025 framework comes down to three checks:

1. Determine the vehicle’s legal classification.
2. Measure the completed glass-and-film combination instead of trusting the film label.
3. Verify every non-VLT requirement, including the AS-1 boundary, nonreflective finish, permitted color, outside mirrors, window-specific certificates, and any exemption documents.¹
