SIZE:
- The Federal Highway Administration (FHWA) has established standards for sign SIZES for allpublic AND paved or unpaved private roads “Open to Public Travel” (Private roads that are gated and posted “No Trespassing” are exempt).
- If you are uncertain about the required size, call or e-mail us and we can tell you the recommended FHWA sign size for your sign and type of road (conventional, multi-lane, etc.
- However… it is your LOCAL JURISDICTION (DOT, Highway Department, County, City Government, etc), and not the FHWA, who determines the required sign sizes for signs on public and private paved/unpaved roads within their jurisdiction.
- Therefore, it is always wise tocheck with your Local Jurisdiction regarding their size requirements prior to ordering any signs.
