Missouri's primary election is just three weeks from today.
And the state Transportation department already has reminded Missourians to keep their political signs off highway rights-of-way.
"They can be a distraction to drivers," spokesman Robert Brendel said. "They can restrict the visibility of drivers to see across roads - (like) somebody pulling out - (or) to see an informational sign that they need to see.
"(And) they get in the way of our roadside operations and, if they're a problem to our maintenance workers, then they will take them down."
Brendel noted that placing signs along the highway right-of-way violates a 1929 state law giving the highway commission to authority to regulate advertising and signs on the right-of-way of state highways. Violation of the law is a misdemeanor.
A department flier about the law says: "MoDOT staff will remove these items wherever they are found."
