What does a sign with an orange background featuring a person digging represent?

A sign with an orange background featuring a person digging is used specifically to indicate the presence of workers in a construction zone. This type of sign alerts drivers to be cautious as they may encounter road work, equipment, or workers who could be in or near the roadway. It emphasizes the need for increased vigilance and reduced speed in areas where construction activities are occurring, thus promoting safety for both the workers and the traveling public.

Other choices represent different scenarios: for instance, "yield to workers" would imply a broader context of giving right-of-way to individuals in the vicinity, while "construction ahead" informs drivers about upcoming work but does not denote the immediate presence of active workers. "End of construction" indicates that the construction zone is finished, which is not the case when seeing the worker sign.
