Correction: Fact brief: Does SD require campaign signs to come down after elections? (Photo: Megan Luther / South Dakota News Watch)State law requires cities to allow campaign signs, which are not allowed on state highway rights-of-way. Corrected on Aug. 11, 2026: An earlier version of this story misstated the breadth of state law. South Dakota law requires cities to allow campaign signs on private property before elections and they must be taken down within seven days after an election. However, there is no state law governing signs outside of cities, though they are not allowed on state highway rights-of-way.
