Utah Window Tint Laws
Published by TintLegal. Content corrected September 19, 2026. Individual source-check dates appear alongside the rules; this is AI-assisted source research, not professional legal review.
Start with the correct window and vehicle
For ordinary passenger car / sedan, front-side requirement: >= 35% combined VLT — conditions apply. Rear-side requirement: No VLT minimum — conditions apply. Rear window: No VLT minimum — conditions apply.
A whole windshield and its upper visor strip have separate rules. Read the conditions below before choosing film. A “no VLT minimum” entry does not remove other restrictions.
Window and vehicle requirements
Window positions only; shading does not simulate tint or visibility. Ordinary passenger car / sedan:
- A — Whole windshield: >= 70% combined VLT — conditions apply. The visor strip is a separate table row.
- B — Front side: >= 35% combined VLT — conditions apply
- C — Rear side: No VLT minimum — conditions apply
- D — Rear window: No VLT minimum — conditions apply
Ordinary passenger car / sedan
Special classes and exemptions require separate assessment; do not infer classification from marketing names.
| Window | Requirement | Conditions and evidence |
|---|---|---|
| Front side | >= 35% combined VLT — conditions apply | Both exterior mirrors are fitted and adjusted to provide the rearward view specified in the official rule. Tolerance, separate from minimum: Officer-meter 5% variance, not an ordinary threshold reduction. §41-6 a-1635 effective 2025-05-07 (checked 2026-09-19) |
| Rear side | No VLT minimum — conditions apply | Both exterior mirrors are fitted and adjusted to provide the rearward view specified in the official rule. §41-6 a-1635 effective 2025-05-07 (checked 2026-09-19) |
| Rear window | No VLT minimum — conditions apply | Both exterior mirrors are fitted and adjusted to provide the rearward view specified in the official rule. §41-6 a-1635 effective 2025-05-07 (checked 2026-09-19) |
| Full windshield | >= 70% combined VLT — conditions apply | Both exterior mirrors are fitted and adjusted to provide the rearward view specified in the official rule. §41-6 a-1635 effective 2025-05-07 (checked 2026-09-19) |
| Windshield visor strip | No VLT minimum — conditions apply | Strip remains within four inches or aboveAS-1, whichever is lower, as specified in the statute. §41-6 a-1635 effective 2025-05-07 (checked 2026-09-19) |
Check a tint VLT requirement
Use a measured combined glass-plus-film VLT reading. A film label alone cannot tell you the installed VLT. This is a limited check, not a certificate of complete compliance.
Choose your state, class and window, then enter the measured VLT.
Read the state rules and official sources
Estimate combined VLT from film and glass specifications
Approximation: glass VLT × film VLT ÷ 100. For example, 80% glass × 35% film = 28%. An estimate is not a calibrated measurement and is never used as a passing calculator result.
Restrictions beyond darkness
Front 35%, windshield 70; officer-meter 5% variance separate. Tint requires mirrors except specified windshield-placement exceptions; metallic/mirrored prohibited.
Window positions: front-side means beside the driver/front passenger; rear-side means behind the driver; rear window means the back-facing glass. The tables separate full-windshield coverage from an upper strip. Vehicle marketing names alone do not resolve statutory classifications.
Medical exemptions
Availability and process not yet verified. A missing form does not mean no exemption exists.
Renewal: Not yet verified; confirm with the issuing authority.
Compare verified medical instructions . Do not treat a medical diagnosis as automatic approval.
Tickets and costs
A reliable statewide total has not been verified. The cited offense, court and local fees determine the amount; dismissal is not automatic.
Official sources and research limits
- §41-6 a-1635 effective 2025-05-07
Front 35%, windshield 70; officer-meter 5% variance separate. Tint requires mirrors except specified windshield-placement exceptions; metallic/mirrored prohibited.
Source checked 2026-09-19. Effective date established: 2025-05-07.
Unknown entries identify specific research gaps. They are not assertions that tint is prohibited or unrestricted. Contact the official motor-vehicle agency to resolve an unclear classification before installation.
Practical questions
Does a 35% film label mean the window measures 35%?
No. With 80% glass, 35% film estimates to 28% combined VLT. Measure the installed combination; understand VLT and estimates .
Does passing the calculator prove full compliance?
No. It checks the verified numerical rule and explicitly confirmed conditions for the selected case. Reflection, color, certification, special uses and approved exemptions may need separate assessment.
Neighboring state research
Use the same vehicle classification when comparing. Nonresident applicability has not been established across these states; crossing a border is not automatically a violation or an exemption.
- Arizona — ordinary passenger front: >= 33% combined VLT
- Colorado — ordinary passenger front: >= 27% combined VLT
