MoDOT Urges Public to Stop Street Sign Vandalism Following Rise in Desoto Area
https://www.modot.org/node/90694

The Missouri Department of Transportation (MoDOT) is asking the public for assistance following a recent increase in vandalism involving road and traffic signs across the region — including a concerning pattern of intentionally removed or knocked down stop signs in the Desoto area along Highway 21 over the past several days. These actions create immediate and serious safety risks for all roadway users and increase maintenance costs for taxpayers.

In recent weeks, crews have discovered multiple signs that have been spray painted, knocked down, or removed entirely. These actions not only disrupt traffic flow but also hinder emergency response teams that rely on accurate signage to reach residents quickly.

“Street signs are critical safety tools,” said District Maintenance Engineer Bob Becker. “When stop signs are vandalized or removed, drivers lose essential guidance that prevents serious or even fatal crashes. We’re asking the community to help protect these resources before someone gets hurt.”
