Window Tint Laws in Wyoming
The exact legal darkness allowed on every window of your vehicle in Wyoming, plus reflection limits, the medical exemption, and what a ticket costs.
How dark you can legally go
Visible-light transmission (VLT) allowed for each window.
Common tint shades, and whether they're legal here
What the shop sells, mapped to the Wyoming limit.
| Film shade | Front side | Back & rear |
|---|---|---|
| 70% (light) | Legal | Legal |
| 50% | Legal | Legal |
| 35% (factory look) | Legal | Legal |
| 20% | Too dark | Too dark |
| 5% (limo) | Too dark | Too dark |
The 28% floor behind the driver does not reach trucks, buses, motor homes, ambulances, limousines, or multipurpose passenger vehicles, which may use any darkness there. Any tint behind the driver triggers the dual-mirror requirement.
Film is sold by its own VLT, but police measure the installed darkness: the film combined with your factory glass. Ask the shop for the net, as-installed VLT before you buy.

Penalties & how it's enforced
What happens if your tint is too dark.
None (no pending change): No recent change to the tint percentages. The 28% floor, the 20% reflectance cap, and the 25% medical floor stand as long-standing law. Film applied before July 1, 1996 was grandfathered down to a 13% floor.
The medical exemption: how to qualify
For drivers with a documented light-sensitivity condition.
What Wyoming drivers get wrong
Wyoming runs a single 28% floor: front side windows, back side windows, and the rear window on a passenger car all need to pass at least 28% of light. SUVs, vans, trucks, and a handful of other classes escape that floor behind the driver and may go as dark as they like there, but any rear tint at all means the vehicle needs both outside mirrors. The windshield stays clear apart from a non-reflective strip along the top, and a documented medical condition can drop the side floor to 25%.
Common questions
What is the legal tint limit in Wyoming?
On a passenger car, front side windows, back side windows, and the rear window all need at least 28% light transmission. SUVs, vans, and several other vehicle classes may use any darkness behind the driver.
Can SUVs and vans have darker rear tint in Wyoming?
Yes. Multipurpose passenger vehicles, trucks, buses, motor homes, ambulances, and limousines are exempt from the 28% floor on windows behind the driver, so any darkness is allowed there. Adding that tint requires both outside mirrors.
Does Wyoming allow a medical exemption for window tint?
Yes. A person whose medical condition makes them sensitive to sunlight may run film down to 25% with physician certification and the director’s authorization. The windshield still may not go below 70% except in the top strip.
Is mirrored or reflective tint legal in Wyoming?
Only up to a point. No film may have a luminous reflectance above 20% on any window, so highly mirrored film is out.
