Is 50% Window Tint Legal in Colorado After the 2026 Regulatory Updates?

No, 50% window tint is illegal in Colorado for passenger vehicles. State law mandates front-side windows allow over 70% light transmission, while rear windows may have up to 27% tint. Non-compliance risks citations and mandatory removal.


Key Regulations for 50% Window Tint in Colorado

  • Front-side windows must permit more than 70% light transmission (VLT ≥ 70%), making 50% tint non-compliant.
  • Rear windows may have up to 27% VLT (73% blockage), but medical exemptions require Colorado DMV approval.
  • Windshield tinting is prohibited except for a non-reflective strip above the AS-1 line (typically 4 inches).

Local enforcement varies, with Denver and Boulder County issuing stricter penalties. The Colorado State Patrol actively cites vehicles during routine stops, particularly in high-traffic corridors like I-25. A 2026 legislative proposal seeks to standardize tint enforcement statewide, potentially eliminating medical exemptions.

Vehicles registered out-of-state must comply with Colorado’s VLT standards within 30 days of residency. Dealers and installers face liability for non-compliant tint applied post-sale. Always verify installer certifications, as Colorado requires licensed professionals to affix tint meeting state specifications. Failure to adhere may result in fines up to $100 per violation, with repeat offenses escalating to vehicle impoundment.
