Staff review of this legislation finds that it is aligned with our principles and merits support.

Thousands of Utahn’s drive outside their home county to and from work every day. For those commuting along the Wasatch Front, they’re all too familiar with the bright sun gleaming in one side of their car on the way to work, and the other on the way home. And strategically placing the sun visor can only keep out so much light, making it difficult to see. A better solution is darker window tinting.

Utah allows windows tinting in the front two windows of a vehicle — but not much. Under current law, 43% of exterior light must be able to pass through. This standard is far brighter than surrounding states, who allow for much darker tint:

  • Idaho: 35%
  • Wyoming: 28%
  • Colorado: 27%
  • New Mexico: 20%
  • Arizona: 33%
  • Nevada: 35%

Representative Phil Lyman is sponsoring House Bill 170 to lower the allowed vehicle tint for the front two windows from 43% to 25% light transmittance.

We live in a desert state that can be extremely hot and bright for many months out of the year. Darker tint can help keep cars cooler, and reduce the vision barrier from the bright sun while going to and from work among other benefits.

Law enforcement may argue that darker window tint makes them feel more unsafe when approaching vehicles. But this is a speculation that simply isn’t based in fact. Plenty of other states have far darker tints, without higher incidents between vehicle passengers and law enforcement.

    I was once pulled over for this and fined in Cedar City. As it turned out, the window tint on the police officer’s car was also in violation of the legal limit. My theory is this useless law as it exists is just another reason for law enforcement to profile people and pull them over for essentially no reason.

      True that. I have had to remove a low-tint on my driver side window to pass Utah state inspection. Such a lame law. will contact state Rep. (I forgot who Draper Rep is)

    I heard that this bill has been dropped? Our current tint law is one that basically no tint is allowed. 25% is very fair and does not endanger officer safety. Officers are trained to observe hands, the only vantage point is the side mirror on approach. Tint or not and officer can demand a window down if an issue comes about. I come from AZ and tint is not an issue for safety there.
