Tinting of front windshield glass to reduce light transmission is not permitted, except for the upper 6 inches of the windshield. For side windows or rear windshield, glass tinting that reduces light transmission to less than 32% or increases light reflectance to more than 20% is not permitted. For SUVs, vans and trucks, the limit is 32% for the driverâs window and the front passenger window only.
1 A: Yes. 2  However, having this level of window film on front doors is not legal in Missouri. 3  Vehicle factory window tint is usually 26%-15% film level. 4  Missouri law states that the front door legal light transmission is 35%, which is lighter than the rear window of your factory tinted vehicle. Aftermarket window film also has many more solar benefits than factory window tint. 2  Factory tint only rejects part of the UV rays, and only rejects a small amount of heat. 3  Aftermarket window film rejects 99% of ultraviolet rays and between 35%-60% of heat, depending on the film level used.
