What the law says
Transparent material is allowed on the topmost portion, with its bottom edge at least 29 inches above the undepressed driver's seat, and it may not be red or amber. Because the material must be transparent, a printed or opaque banner is not legal in California — only a clear tint band. California expressly bars opaque lettering in this strip, so a printed banner is not legal even though a clear tint band is. The 7-inch figure often quoted is the separate corner-sticker allowance in § 26708(b).
