The Minnesota Department of Transportation reminds everyone that the placement of campaign and other advertising signage on all state, county, city and township roads and highway rights of way is not allowed under state law.
Highway rights of way include driving lanes, inside and outside shoulders, ditches and sight corners at intersections. MnDOT crews are required to remove unlawfully placed signs. When improperly placed signs are removed by MnDOT, every effort is made to temporarily store the sign at one of its local maintenance truck stations until the owner retrieves it.
Landowner consent is needed before signs can be placed on private property outside of the right of way. Violation of the law is a misdemeanor. Civil penalties also may apply if the placement of signage contributes to a motor vehicle crash and injures a person or damages a motor vehicle that runs off the road.
It is also illegal to place advertising materials on public utility poles, trees and shrubs, and painting or drawing on rocks or natural features.
