SC Tint Law for SUVs, Vans and Pickups: The Rear-Window Exception
Park a crossover, a minivan and a crew-cab pickup side by side and South Carolina's tint law may give three different answers for the windows behind the driver. The reason is one sentence, subsection (I) of S.C. Code § 56-5-5015, which exempts some vehicle types from the light limit behind the driver and pointedly keeps pickups in.
This guide explains that exception: which vehicles get it, how to confirm your vehicle's classification from the label on the door edge, what the exception does not change, and how pickup owners can still tint the back half of the cab legally.
The short answer
In South Carolina, the 27 percent light limit does not apply to windows behind the driver on multipurpose passenger vehicles, other trucks, buses, trailers, mobile homes and RVs, but it does apply on pickup trucks. Many SUVs and minivans are classified as MPVs; the certification label on the driver's door edge or pillar lists the class. Front side windows stay at 27 percent combined on every vehicle.
Key points
- Subsection (I) lifts the light transmittance requirement behind the driver on MPVs, other trucks, buses, trailers, mobile homes and RVs, but not on pickup trucks.
- A multipurpose passenger vehicle carries ten people or fewer and is built on a truck chassis or with features for occasional off-road use.
- The federal certification label on the driver's door edge or pillar lists the vehicle's type classification, such as MPV or truck.
- The exception covers only windows behind the driver; front side windows on every vehicle need 27 percent combined.
- Film behind the driver on an MPV still has to be nonreflective, not red, yellow or amber, and labeled with a certificate.
The sentence
What Subsection (I) Says
Subsection (I) of the tint law reads: the light transmittance requirement of this section applies to windows behind the driver on pickup trucks, but does not apply to windows behind the driver on other trucks, buses, trailers, mobile homes, multipurpose passenger vehicles, and recreational vehicles.
Two things are packed into that sentence. First, there is a list of vehicle types whose rear side windows and back glass have no minimum light transmission. Second, pickup trucks are named on purpose and kept under the limit, even though a pickup is otherwise a kind of truck.
The exception is about windows behind the driver. It does nothing for the windows immediately to the driver's left and right. Those front side windows follow subsection (C) on every vehicle: film plus factory glass must pass at least 27 percent of visible light.
Definitions
What Counts as a Multipurpose Passenger Vehicle
Subsection (J)(5) defines a multipurpose passenger vehicle as a vehicle with motive power designed to carry ten persons or less which is constructed either on a truck chassis or with special features for occasional off-road operation. The federal definition in 49 CFR 571.3 says essentially the same thing, with exceptions for low-speed vehicles and trailers.
That is why many SUVs and minivans fall into the MPV class, but looking like an SUV is not the test. The classification comes from how the manufacturer certified the vehicle under federal rules, and two vehicles with similar shapes can be certified differently.
The statute also defines a truck as a vehicle designed primarily to transport property or special purpose equipment, and a bus as one designed to carry more than ten people. Those definitions matter for work vans and large passenger vans, which may be classified as trucks or buses rather than MPVs.

How to Read Your Vehicle's Classification
Open the driver's door
Federal rules require the certification label on the hinge pillar, the door-latch post or the edge of the driver's door, or on the left side of the instrument panel if none of those works.
Find the type line
Under 49 CFR 567.4, the label must state the vehicle's type classification as defined in 49 CFR 571.3, with examples such as truck, MPV, bus and trailer.
Match it to subsection (I)
MPV, bus, trailer or a truck that is not a pickup: the light limit does not apply behind the driver. Passenger car or pickup truck: the 27 percent combined rule applies to every side and rear window.
Keep a photo
A phone photo of the label is handy if the question ever comes up at a traffic stop or when you sell the vehicle.
The statute does not define pickup truck. If your vehicle's label says truck and you are unsure whether it counts as a pickup, treat the 27 percent rule as applying and ask SCDPS or a lawyer before going darker.
Pickups
Why Pickups Are Treated Like Cars Behind the Driver
On a pickup truck, every window behind the driver follows the same rules as a car: the rear doors on a crew cab, the small rear windows on an extended cab and the back glass of the cab all need at least 27 percent combined light transmission if film is added.
The back glass is the rear-most window under subsection (D), so it carries two extra conditions. The film must be nonreflective and pass the 27 percent combined test, and if any film is on the rear-most window, the truck needs both a right and a left outside rearview mirror. A sliding rear window is part of that back glass, so the same conditions apply to it.
Many pickups come with dark factory glass in the rear doors and back window. That glass alone is not a tint violation, because the light rules apply only where aftermarket film has been added. Adding film over it is where the trouble starts: the combined reading of dark factory glass plus film can fall below 27 percent even with a light film.
Still applies
What the Exception Does Not Change
Subsection (I) removes only the light transmittance requirement behind the driver. It says nothing that lifts the other rules, so on an MPV's rear windows you should treat these as still in force.
- Nonreflective film only. A mirror-finish film behind the driver is still a problem, however light it is.
- No red, yellow or amber film on any window.
- A certificate of compliance on every window that has aftermarket film, rear windows included.
- Both outside mirrors if the rear-most window is filmed.
- The windshield rule: film only along the top, no lower than the AS1 line, and none if the line is not visible.
- The front side windows at 27 percent combined, with no MPV exception.
Factory glass
Why SUVs Come With Privacy Glass and Sedans Do Not
Federal glazing rules explain the factory difference. In its 2012 rulemaking notice on Standard No. 205, NHTSA stated its position that on passenger cars all windows in the passenger compartment are requisite for driving visibility and must pass at least 70 percent of light. For trucks, buses and MPVs, the same notice says glazing is subject to that test only as a windshield, beside the driver, or as the rear-most window when it is used for driving visibility.
That is why an SUV can roll off the line with dark rear glass and a sedan cannot. South Carolina's subsection (I) follows a similar logic for aftermarket film behind the driver, with its own carve-out that keeps pickups under the limit.
The practical result for owners: an MPV's rear windows can often take darker film than a car's, while the front doors on both stay at 27 percent combined. Expect the fronts to look lighter than the rear on most SUVs, even after tinting.
| Vehicle type on the label | Front side windows | Rear side windows and back glass |
|---|---|---|
| Passenger car | 27% combined or lighter | 27% combined or lighter |
| Multipurpose passenger vehicle (MPV) | 27% combined or lighter | No light transmittance limit |
| Pickup truck | 27% combined or lighter | 27% combined or lighter |
| Other truck (not a pickup) | 27% combined or lighter | No light transmittance limit |
| Bus, motor home or recreational vehicle | 27% combined or lighter | No light transmittance limit |
Every filmed window must still be nonreflective, not red, yellow or amber, and carry a certificate of compliance. Summary of S.C. Code Ann. § 56-5-5015(C), (D) and (I); not legal advice.

Common questions
Is a minivan an MPV under South Carolina tint law?
Often, but check the vehicle rather than assuming. South Carolina defines an MPV as a vehicle for ten people or fewer built on a truck chassis or with features for occasional off-road use, and the federal definition is similar. The certification label on the driver's door edge or pillar lists the type classification the manufacturer gave it.
Can I tint my SUV's front windows as dark as the factory rear glass?
Usually not. The MPV exception in subsection (I) covers only windows behind the driver. The front side windows of every vehicle must pass at least 27 percent of visible light through film and glass combined. If your rear privacy glass reads darker than 27 percent on a meter, no legal front film can match it exactly; the goal becomes a close, legal look.
Why are pickup trucks excluded from the rear-window exception?
The statute names pickup trucks specifically and says the light transmittance requirement applies to windows behind the driver on them, while exempting other trucks. The law does not explain the choice. In practice, it means a crew-cab pickup's rear doors and back glass follow the same 27 percent combined rule as a car's.
Does a work van with no rear seats get the exception?
It depends on how it is classified. If the label lists it as a truck, the text of subsection (I) exempts windows behind the driver on trucks other than pickups. If it is listed as an MPV or bus, those are exempt too. Front side windows stay at 27 percent combined either way. If in doubt, ask SCDPS or a lawyer before going darker.
