Window Banners in South Dakota
South Dakota regulates windshield banners by obstruction, not transparency: material that obstructs or reduces the driver's clear view is prohibited, and sunscreening film may not reach below the AS-1 line or sun-visor point. A printed banner is illegal only when it obstructs the view.

What the law says
SDCL 32-15-2.9 bars sunscreening that obstructs or reduces the driver's clear view and keeps film above the AS-1 line or the lowest point of the sun visor (Class 2 misdemeanor). Nontransparent material is governed separately by SDCL 32-15-5: a sign, poster, or other nontransparent material on the windshield is a petty offense only when it obstructs the driver's clear view — there is no transparency requirement as such.
