Answer :
The statement "signs in work areas are typically diamond-shaped, orange, displaying black letters or symbols, and serve as a warning that people are working on or near the highway" is true because this is the standard convention for work zone signs according to the MUTCD issued by the FHWA.
The correct answer is true.
Work zones are typically established when road maintenance, repair, or construction is done. To alert drivers of these work areas, warning signs are posted along the roadways. These warning signs are designed to convey important information to drivers, such as the presence of workers or the need to reduce speed or change lanes.
One of the most common work zone signs is the diamond-shaped, orange sign with black letters or symbols. These signs indicate that people are working on or near the highway and that drivers should take extra caution when passing through the area. The colour orange is used because it is evident and stands out against most backgrounds, making it easier for drivers to spot the sign from a distance.
