Which statement is not true regarding driving in highway work zones?

The selection indicating that posted speed limits apply when no workers are present is incorrect because, in highway work zones, specific speed limits are often established for the safety of both workers and drivers. These limits usually remain in effect at all times, irrespective of whether workers are present or not. The intent behind maintaining these speed limits, even in the absence of workers, is to ensure that drivers remain aware and cautious in areas where there may still be hazards related to ongoing construction or maintenance work.

In many jurisdictions, speed limits in work zones are about more than just the visibility of workers; they are also about the potential dangers posed by construction equipment, barriers, and other conditions that can make driving more hazardous. Therefore, it is important for drivers to adhere to posted signs and obey speed restrictions even if no workers are currently visible.
