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 type only, along the top of the windshield, not extending downward beyond the AS-1 line or more than five inches from the top, whichever is closer to the top; may not be red, yellow, or amber. The statute sets no VLT figure for the windshield itself (the 70% figure appears only in the medical-exemption subsection). | Same as sedan |
| Front side | 28% VLT or lighter | 28% VLT or lighter |
| Back side | 28% VLT or lighter | No VLT limit |
| Rear | 28% VLT or lighter | No VLT limit |
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
No sunscreening device or tinting film with a luminous reflectance of light exceeding 20 percent may be applied to any window (§ 31-5-962(f)); windshield film must additionally be a nonreflective type
Colors
Windshield film may not be red, yellow, or amber (§ 31-5-962(c)). The statute states no color restriction for side or rear window film.
Medical exemption
§ 31-5-962(m): a vehicle operated by or regularly used to transport a person whose medical condition renders them susceptible to harm from sunlight or bright artificial light may be equipped, on its windshield and any or all windows, with film reducing light transmission to not less than 25%; windshield film may not take total light transmittance below 70% except for the upper five inches or the AS-1 line, whichever is closer to the top. The driver or an occupant must have in their possession a certificate issued by the WYDOT director, issued only on a signed statement from a licensed physician or optometrist identifying the person and stating the film is necessary to safeguard their health. Certificates are valid while the condition persists or until the vehicle is sold, and the director may issue one or more certificates to an individual or a family.
Stickers & certification
None required — no installer certification or compliance sticker appears in § 31-5-962 (the medical certificate under subsection (m) is the only document required)
Measurement tolerance
This state does not state a measurement tolerance in the sources we checked.
Penalties
§ 31-5-962 contains no penalty; the general Title 31 penalty in § 31-5-1201 applies — a misdemeanor punishable by a fine of not more than $200 for a first conviction, not more than $300 for a second conviction of the same offense within one year, and not more than $500 or up to six months' imprisonment or both for a third or subsequent conviction within one year of the first, plus a $5 police officer continuing education and training fee under § 31-5-1201(h).
Notes
The SUV/van difference rests on § 31-5-962(h): 'The requirements of this section shall not apply to windows behind the driver of trucks, buses, motor homes, ambulances, limousines and multipurpose passenger vehicles.' Because it exempts the requirements of the whole section (not just light transmittance), the 20% reflectance cap also does not reach those rear windows. 'Multipurpose passenger vehicle' is defined in (a)(iv) as a vehicle designed to carry ten persons or less constructed either on a truck chassis or with special features for occasional off-road operation — which covers most SUVs, vans and pickups but is a classification question, not a body-style question. Subsection (b) applies the section to 'an enclosed motor vehicle', and (n) extends it to multipurpose vehicles as defined in § 31-1-101(a)(xv)(M) when equipped with a windshield and an enclosed cab. Dual outside rearview mirrors are required whenever film is added to any window behind the operator. An obsolete grandfather clause, (j), allowed 13% VLT for film applied before July 1, 1996. Installers are separately barred by (k) from applying non-compliant film.
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 VLT limit, rear no VLT limit.
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 type only, along the top of the windshield, not extending downward beyond the AS-1 line or more than five inches from the top, whichever is closer to the top; may not be red, yellow, or amber. The statute sets no VLT figure for the windshield itself (the 70% figure appears only in the medical-exemption subsection).
Does Wyoming allow a medical exemption for darker tint?
What the source says: § 31-5-962(m): a vehicle operated by or regularly used to transport a person whose medical condition renders them susceptible to harm from sunlight or bright artificial light may be equipped, on its windshield and any or all windows, with film reducing light transmission to not less than 25%; windshield film may not take total light transmittance below 70% except for the upper five inches or the AS-1 line, whichever is closer to the top. The driver or an occupant must have in their possession a certificate issued by the WYDOT director, issued only on a signed statement from a licensed physician or optometrist identifying the person and stating the film is necessary to safeguard their health. Certificates are valid while the condition persists or until the vehicle is sold, and the director may issue one or more certificates to an individual or a family. Confirm the current process with the agency named before you have film installed.
Do I need a tint sticker or certificate in Wyoming?
None required — no installer certification or compliance sticker appears in § 31-5-962 (the medical certificate under subsection (m) is the only document required)
