Modifies provisions relating to transportation

HB 1853 repeals multiple existing Missouri transportation laws and replaces them with a new provision (section 229.222) allowing counties, cities, or villages to designate streets, roads, or highways as memorial roads for law enforcement officers, emergency personnel, or military members killed in the line of duty. Local governments that create such memorial roads must cover the costs of signs and maintenance. This bill directly affects local jurisdictions by establishing a formal process for honoring fallen public safety personnel through road naming, without imposing new state-level requirements or funding.
