Window Banners in Montana
No sign, poster, or non-transparent material may obstruct vision through the windshield, and sunscreening must be clear and transparent below the AS-1 line — confining any strip to the area above that line. Because the material must be transparent, a printed or opaque banner is not legal in Montana — only a clear tint band.
