With upcoming November elections, the Minnesota Department of Transportation reminds campaigners that state law prohibits placement of private signs of any kind (i.e., political and other advertising signage) on highway right-of-way in Minnesota. Highway rights of way include driving lanes, inside and outside shoulders, ditches, sight corners at intersections, and boulevards in urban areas.

In addition, state law says that signs may not be placed on private land without the consent of the landowner.

Violation of the law is a misdemeanor. Civil penalties may also apply if the placement of such material contributes to a motor vehicle crash, creates injury to a person, or causes damage to a motor vehicle that runs off the road.

The Minnesota Outdoor Advertising Control Act, Minnesota Statute 173.15, also prohibits placing advertising materials on public utility poles, trees and shrubs, and painting or drawing on rocks or natural features.

MnDOT workers are required to take down private signs located on the state highway right-of-way. County, city and township employees administer these laws on their roads.
