Final answer:
Orange-colored signs on the road warn of construction ahead, and they are crucial for ensuring pedestrian safety in areas with traffic, like near school zones.
Step-by-step explanation:
Orange-colored signs typically warn drivers of construction ahead. They are designed to alert drivers to various construction-related road conditions, including detours, roadwork zones, and maintenance on roadways. It is essential for drivers to pay attention to these signs as they indicate temporary traffic conditions where extra caution is needed. These orange signs serve an important role in maintaining pedestrian safety, especially near school zones and campus areas where students often cross intersections. A traffic signal is also useful in such places to manage vehicle speed and provide safe crossing times for pedestrians.
