Placement of campaign signs and other unauthorized objects in state highway rights of way is not allowed under state law, according to the Minnesota Department of Transportation. In addition, campaign signs may not be placed on private property outside of the right of way limits without landowner consent.

Highway rights of way include the driving lanes, inside and outside shoulders, ditches and sight corners at intersections.

MnDOT crews will remove any unlawfully placed signs and impound them at a maintenance truck station.

Violation of the law is a misdemeanor. Civil penalties also may apply if the placement of such material contributes to a motor vehicle crash and injures a person or damages a motor vehicle that runs off the road.

In addition, the Minnesota Outdoor Advertising Control Act prohibits placing advertising materials on public utility poles, trees and shrubs, and painting or drawing on rocks or natural features.

Political campaign signs are treated in the same way as any other signs wrongly placed on state highway property by businesses, churches, private citizens or charitable groups.
