Safety message criteria specification on changeable message signs for the Department of Transportation

This bill requires Minnesota's Department of Transportation to adopt specific safety message standards for changeable highway signs by July 1, 2025. It mandates that messages must be clear, simple, and avoid slang, hashtags, or cultural references that could confuse drivers, while focusing on minimizing distraction. The bill directly affects the Department of Transportation (which must implement these rules) and all road users who encounter these signs.
