Traffic signs are a vital element of the massive transportation network that crisscrosses the country. Whether posted on highways or back roads, in suburban neighborhoods or city streets, these signs communicate rules, warnings, directions and other information that is essential for drivers and pedestrians.

Ensuring that these signs are well maintained is a major safety concern, and the U.S. Department of Transportation Federal Highway Administration (FHWA) issues detailed guidelines for the local maintenance of signs and sign supports. In the wake of damage caused by winter weather and snowplowing operations, maintenance crews will be making it a priority to repair and replace signs now that spring has arrived.
