In the state of California, you are allowed to tint the top 4 inches of your windshield with non reflective film. This is commonly known as a sun visor or eyebrow. The front driver and passenger doors must have a VLT of 70% or above. The rear doors, rear quarters, and rear windshield can be of any darkness. Ace Auto Tint encourages everyone to follow the local tint laws and be safe on the road.
