50-State Standards Context
Federal sign R3-1g is part of the nationwide standardized study baseline. States may use the national MUTCD directly, supplement it, or use a state MUTCD. This does not mean every sign is installed everywhere, and state-specific codes, aliases, or variants are not inferred without independent verification.
State implementation model cross-checked in Gate 2 on June 4, 2026. Each state's official source controls any sign-specific code, alias, variant, or usage claim. Delaware was checked again on September 7, 2026 and its 2026 MUTCD remained marked pending approval.
