ST. PAUL, Minn.—With upcoming November elections, the Minnesota Department of Transportation reminds campaigners that state law prohibits placement of political or advertising signs on highway right-of-way.

These areas include driving lanes, inside and outside shoulders, ditches, sight corners at intersections, and boulevards in urban areas. It also includes displaying flags or other signs on bridges over traffic.

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

Violation of Minnesota Statute 160.27 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 political or advertising signs located on the state highway right-of-way. County, city and township employees administer the laws on their roads. You can retrieve signs by contacting your local MnDOT office.
