Window Tint Laws in Idaho
Laws change. Verify current requirements with your local DMV/RMV before choosing or installing film. This is not legal advice.
VLT is visible light transmission: lower percentages mean darker windows. A film's labeled shade is not necessarily the finished glass-plus-film reading. The limits below cover ordinary passenger cars unless stated otherwise.
- Front side windows
- At least 35% transmission ±3% under statutory film/device wording.
- Rear side windows
- At least 20% transmission ±3% under statutory film/device wording.
- Back window
- At least 35% transmission ±3% under statutory film/device wording.
- Windshield strip
- Nonreflective film above AS-1; if no identifiable line, no lower than six inches below exposed windshield top.
