FAQ Answer
  • Front windshield: at least 70% light transmittance (no more than 30% tint) below the AS-1 line or below the top 5 inches of the windshield.
  • Other windows: at least 50% light transmittance (no more than 50% tint)
    • When calculating total tint, the factory tinting on windows must be included. For example, a 50% tint added to a window with a 30% factory tint would exceed the allowed limit.
  • Windows behind the operator: may be tinted with zero light transmittance as long as the motor vehicle is equipped with outside mirrors on both sides.
