Regulatory sign


Reference: §2G.18 • Table 2G-1
Drawing units: inches (in.) unless noted on the sheet.
Controls or restricts road-user behavior as indicated by the legend or symbol.
Ask naturally. Sign and installation answers use indexed MUTCD, FHWA, Standard Highway Signs, installation, and official state DOT sources. All 50 state source lanes are available, but state material is used only when your question explicitly identifies that state.
AI can make mistakes. Verify critical measurements, agency requirements, and field conditions before acting.
Ask about road signs, sizes, placement, supports, installation, pavement markings, work-zone signing, or state sign standards.
