Text can be used with a diamond symbol to delineate__________.

The correct answer is that text can be used with a diamond symbol to delineate reserved lanes. In traffic signage, a diamond shape is commonly associated with specific lanes designated for certain types of vehicles or use. For example, these lanes may be reserved for carpooling, buses, or other designated vehicles that meet specific criteria, effectively communicating to drivers that only those vehicles may enter or use these lanes. The inclusion of text alongside the diamond symbol serves to clarify the exact restrictions or permissions related to the use of these reserved lanes, ensuring that drivers understand which lanes are restricted and who can legally use them. This practice is key in maintaining order and safety on the road, as it reduces confusion regarding lane usage.
