Is 70% tint legal in all states?

70 percent tint, which allows 70 percent of visible light to pass through, is legal in all states for side and rear windows, but for windshields, legality varies slightly, though 70 percent is generally the lightest and most universally legal tint. For front side windows, every state allows at least 70 percent VLT, because most states require 25 percent to 70 percent on front windows, and 70 percent is lighter than all those minimums, meaning it allows more light than required. California is the strictest state, requiring 70 percent on front side windows, so 70 percent is exactly legal there. States that allow darker tints like 35 percent or 20 percent on front windows also allow 70 percent because it is lighter. For rear side windows and rear windshields, all states allow 70 percent because most allow any darkness on rear windows. For windshields, most states allow 70 percent or higher clear ceramic film on the entire windshield for UV and heat rejection, as long as it is not visibly dark and does not have high reflectivity, though some states only allow tint on the top few inches. So a 70 percent ceramic film that is almost clear is generally considered legal on windshields in all states, but you should check local inspection rules. Overall, 70 percent is the safest, most universally legal tint percentage.
