Tint limits by window
Percentages are the minimum VLT allowed. A lower number is a darker tint.
| Window | Sedans & coupes | SUVs, trucks & vans |
|---|---|---|
| Windshield | 70% VLT; tint only above AS-1 line or top 4 inches | 70% VLT; tint only above AS-1 line or top 4 inches |
| Front side windows | 35% VLT | 35% VLT |
| Back side windows | Any darkness | Any darkness |
| Rear window | Any darkness (dual side mirrors required) | Any darkness (dual side mirrors required) |

How Utah compares
Utah allows 35% VLT on the front side windows of a car. That is darker than 15 states allow and lighter than 16 states permit, and 18 other states use the same limit. If you want to see what 35% VLT actually looks like on glass, compare it in our tint percentage examples.
Utah borders Arizona, Colorado, Idaho, Nevada, New Mexico and Wyoming. None of its neighbors are stricter about front windows, so legal Utah tint is legal next door too. Shops in Arizona, Colorado, New Mexico and Wyoming can legally install darker film than Utah allows, so check the meter reading if you tint across the border. Our guide to crossing state lines with tinted windows explains how out-of-state cars are treated.
Sedans vs SUVs, trucks and vans
Utah uses the same limits for every vehicle type: 35% VLT on the front side windows, any darkness on the back side windows and any darkness on the rear window, whether you drive a sedan, SUV, pickup or van.
Many SUVs and trucks leave the factory with dark privacy glass behind the driver. Because most states measure the combined reading of film plus glass, adding film over privacy glass drops the number further than the film label suggests. See how film and glass add up in our VLT guide.
Windshield tint in Utah
The rule for the windshield is: 70% VLT; tint only above AS-1 line or top 4 inches. The AS-1 line is a small mark etched near the top of the glass; our guide shows how to find the AS-1 line on your car.
Choosing film that passes in Utah
Reflectivity is regulated too: no metallic or mirrored appearance allowed on any window or the windshield. Metallic films are the type most likely to run into reflectivity limits, while carbon and ceramic films are non-reflective. Compare them in types of window tint film.
Most installers in Utah meter the glass before and after the install so you leave with a reading inside the limit. Ask for the meter reading on your receipt; it is useful if you are ever stopped.

Compare penalties in every stateUtah medical exemption
Utah Code § 41-6a-1635 contains no medical exemption or physician-certification process, and the Utah Highway Patrol's tint guidance describes none. Drivers with light-sensitive conditions can use any darkness on rear side and rear windows, but the 35% front side and 70% windshield limits apply to everyone.
