JEFFERSON CITY — The Missouri Department of Transportation is testing new ways of combatting vandals who splat highway signs with paint.
The department says Missouri is the first state in the nation to test various types of paint remover for use on highway signs.
It says cleaning a paint-splattered sign instead of replacing it could save as much as $1,000, depending on the sign's size.
The department says most paint-removal products strip away the materials that make the sign reflective. But after extensive research, the agency says it has found products that will clean the sign without damaging its visibility.
