(St. Paul, MN) — The state Department of Transportation is reminding Minnesotans about the rules regarding political signs near streets and highways. State law prohibits the placement of political signs along the highway right-of-way, including driving lanes, shoulders, ditches and intersections. Displays of flags and other signs on bridges over traffic are also prohibited. Signs cannot be placed on private property without the owner’s consent. State law also prohibits placing advertising on utility poles, trees and shrubs as well as painting or drawing on rocks and other natural features.
