Minnesota Window Tint Laws (2026): Legal VLT Limits
Minnesota Window Tint Laws (2026): Legal VLT Limits
In Minnesota, front side windows, back side windows, and the rear window all require at least 50% VLT (visible light transmission) for passenger cars. Pickups, vans, limousines, and funeral and police vehicles are exempt from the back-side and rear-window limits.
What is the legal tint limit in Minnesota?
Minnesota's window tint rules appear in Minn. Stat. 169.71. The key concept is Visible Light Transmission: a higher VLT percentage means a lighter, less restrictive film that lets more light through, while a lower VLT percentage means a darker film that blocks more light. Minnesota uses a 50% VLT floor, which is one of the lighter (less permissive) standards in the country.
For passenger cars, all three window groups must meet 50% VLT: the front side windows, the back side windows (behind the driver), and the rear window. Unlike many states that allow SUVs and vans to run any darkness on rear windows, Minnesota's standard rule applies equally to sedans. However, specific vehicle categories are fully exempt from the back-side and rear-window limits: pickups, vans, limousines, and funeral and police vehicles may use any tint darkness on windows behind the driver.
| Window | Passenger Cars | Pickups, Vans, Limos, Funeral/Police |
|---|---|---|
| Front side windows | 50% VLT minimum | 50% VLT minimum |
| Back side windows | 50% VLT minimum | Exempt (any darkness) |
| Rear window | 50% VLT minimum | Exempt (any darkness) |
| Windshield (below roofline) | No aftermarket tint | No aftermarket tint |
Minnesota applies a measurement tolerance of plus or minus 3%, which is the national standard. A front side window reading of 47% on a tintometer falls within compliance under that tolerance.
Windshield tint rules in Minnesota
Minnesota prohibits any additional aftermarket tint on the front windshield. Unlike many states that allow a clear strip at the top above the AS-1 line, Minnesota's statute does not permit any applied tint film on the windshield at all. Factory-installed tinted glass embedded during manufacturing is treated differently from aftermarket film and is generally permissible, but no aftermarket film may be added.
The reflectivity limit of 20% luminous reflectance applies to all tinted windows in Minnesota, which is stricter than the 35% cap many other states use. Films with a mirrored appearance are specifically prohibited. There are no named banned tint colors in the statute, but any highly reflective metallic or mirror-finish film would almost certainly exceed the 20% reflectance cap and would not be lawful.
Medical exemptions
Minnesota allows a medical exemption under Minn. Stat. 169.71. A licensed physician must provide a written statement documenting the medical need for additional tint. The exemption statement is valid for up to two years, or indefinitely if the physician certifies the condition is permanent. The driver must keep the physician's statement in the vehicle and present it during any traffic stop where the tint is questioned.
Qualifying conditions typically involve sensitivity to ultraviolet or visible light, such as lupus, xeroderma pigmentosum, photosensitive eye conditions, or certain skin disorders. The exemption allows darker tint than the 50% standard on the affected windows, but the exemption document is the operative authorization and must accompany the vehicle at all times.
There is no pre-registration process with the DMV required to claim the exemption. The physician's written statement, current and signed, is sufficient documentation.
How tint is measured and certified in Minnesota
Minnesota requires a compliance sticker: a permanent mark placed between the tint film and the glass on the driver-side window. The sticker must display the film's measured transmittance (VLT) and reflectance values. This requirement places the responsibility on the installer to mark the film at the time of installation, giving officers a fast reference point during traffic stops without the need to use a tintometer every time.
Enforcement otherwise relies on a VLT meter (tintometer) at roadside. The plus-or-minus 3% tolerance is applied in enforcement, meaning a reading of 47% on a front side window or 47% on a rear window would still be compliant. Installers who apply film that does not meet the 50% standard can face a misdemeanor charge, which is a stronger deterrent than in states that only penalize the vehicle owner.
Penalties for illegal tint in Minnesota
Under Minn. Stat. 169.71, selling or applying window film that does not comply with the statute is a misdemeanor. Misdemeanor charges in Minnesota can result in up to 90 days in jail and a fine up to $1,000, though penalties for a first-time tint violation typically run toward the fine end. The misdemeanor classification is directed primarily at commercial installers and dealers, but vehicle owners who drive with non-compliant tint may also face traffic citations.
The compliance sticker requirement means that during a stop, an officer can quickly check whether the film was installed to spec. If no sticker is present, the vehicle is immediately suspect and may be subject to a meter reading. A vehicle with clearly non-compliant tint and no sticker gives officers grounds to cite both the installation and the operation of the vehicle in that state.
If you want to tint your windows in Minnesota
Minnesota's 50% VLT rule means you should choose a film rated at 50% VLT or lighter for all windows on a passenger car to stay comfortably above the compliance floor. With the 3% tolerance, a film rated at exactly 50% may read as low as 47% on a meter and still pass, but going with 50% or above on paper gives you a clear margin.
For pickup trucks, vans, and limousines, the back side and rear windows are exempt, meaning you may use any darkness you prefer behind the driver. Your front side windows still require 50% VLT regardless of vehicle type.
Use a reputable installer who works with the compliance sticker requirement. The sticker must be placed between the film and the glass on the driver's side at installation. Ask for the installer's documentation showing the film's rated VLT so you have a second record on file. If you have a qualifying medical condition, obtain the physician's statement before installation so the film you choose is covered by the exemption from day one.
