Legal tint limits at a glance
VLT is the share of light the window must let through — a lower number is darker film, and the reading includes the factory glass.
| Window | Sedans | SUVs, vans & trucks |
|---|---|---|
| Windshield | Nonreflective only, top of windshield only, not beyond the AS-1 line or 5 inches from the top (whichever is closer); may not be red, yellow, or amber | Same as sedan |
| Front side | 28% VLT or lighter | 28% VLT or lighter |
| Back side | 28% VLT or lighter | No limit stated |
| Rear | 28% VLT or lighter | No limit stated |
Dual side mirrors required if the rear is tinted? Yes — this state requires dual outside mirrors when the rear window is tinted.
Is my tint legal here?
Film darkness and glass darkness multiply. Enter the film you are considering and the VLT of the bare glass to get the number a meter would read.
70 for tinted OEM glass, 80 for clear
Net VLT 14% 20% film × 70% glass
Pass/fail compares net VLT against the limits on this page only. Some states apply a measurement tolerance — see Measurement tolerance below — and none of this replaces a meter reading on your own glass.
The rest of the rule
Reflectivity
Luminous reflectance may not exceed 20% on any window
Colors
Windshield strip may not be red, yellow, or amber; no color restriction stated for side/rear window tint
Medical exemption
WYDOT Director issues a certificate (kept in the vehicle) based on a signed statement from a licensed physician or optometrist; allows down to 25% VLT on all windows and the windshield (windshield still floor of 70% except top 5in/AS-1 line); valid while the condition persists or until the vehicle is sold; one or more certificates may be issued per individual/family
Stickers & certification
none found (no sticker required; only a medical-exemption certificate for that specific case)
Measurement tolerance
This state does not state a measurement tolerance in the sources we checked.
Penalties
No penalty stated within §31-5-962 itself; general Title 31 misdemeanor penalty (§31-5-1201) applies: up to $200 fine (1st conviction), $300 (2nd within 1 yr), $500 and/or up to 6 months jail (3rd+ within 1 yr), plus a $5 officer-training fee
Notes
Trucks, buses, motor homes, ambulances, limousines, and 'multipurpose passenger vehicles' (≤10 occupants, truck chassis or off-road features) are fully exempt from the front-side-window/rear-window darkness limits for windows behind the driver, i.e., can go any darkness behind the driver — but the statute is silent on whether ordinary consumer SUVs necessarily qualify as 'multipurpose passenger vehicles' in every case, so this was applied to the suv_van bucket with some interpretive judgment. A now-obsolete grandfather clause allowed 13% VLT for tint applied before July 1, 1996.
Wyoming tint questions
What is the darkest legal tint in Wyoming?
For a sedan in Wyoming, front side windows must let at least 28% of light through, back side windows at least 28%, and the rear window at least 28%. Lower VLT means darker glass, so those percentages are floors, not targets, and the meter reads the film and the factory glass together. SUVs, vans and trucks are listed separately: front side 28%, back side no stated number, rear no stated number.
Is 20% tint legal in Wyoming?
No, not on the front side windows. Wyoming requires at least 28% VLT there and 20% is darker than that, before you even account for the factory glass, which makes the reading darker still. The back side windows have a 28% floor, so 20% is too dark there too.
Can I tint the windshield in Wyoming?
Wyoming's rule for the windshield: Nonreflective only, top of windshield only, not beyond the AS-1 line or 5 inches from the top (whichever is closer); may not be red, yellow, or amber
