Traffic engineers use the Manual on Uniform Traffic Control Devices, or MUTCD, when selecting roadway signage. This signage can be regulatory (e.g. “Stop”), cautionary (e.g. “Pavement Ends”) or wayfinding in nature (e.g. “2 miles to Downtown”).
Below are links to the online chapters of the MUTCD indicating approved signage related to bicycling.
Many communities in Georgia use the W11-1 sign combined with either W16-1P, R4-1, R4-2*, or R4-11* (those marked with an * are preferred).
