HIGHWAYS: Provides with respect to highway sign maintenance (OR INCREASE SD EX See Note)

HB 849 establishes a statewide program requiring the Louisiana Department of Transportation to proactively maintain and repair interstate highway signs. The bill mandates regular cleaning, application of eco-friendly ceramic sealants to extend sign lifespan, real-time geotagged reporting of damaged signs, and submission of before/after photos for accountability. It directly affects the Department of Transportation and state/local highway maintenance agencies, applying to all regulatory (e.g., speed limits), warning (yellow diamond signs), and guide signs on interstates. Key provisions include safety protocols for maintenance crews, environmental considerations for cleaning methods, and requirements for detailed reporting to prioritize repairs and reduce long-term costs. The program aims to enhance road safety, improve public image, and achieve cost savings through systematic maintenance.
