Final answer:
Traffic signs are essential for C. directing traffic, making decisions on the road, and enforcing stops to ensure safety for both drivers and pedestrians, while helping to reduce accidents.
Step-by-step explanation:
The purpose of traffic signs is to direct, decide, and stop. Traffic signs serve critical functions for the safety and efficiency of our roadways. They provide directions to drivers, which helps prevent accidents and ensure smooth traffic flow. For example, at a busy intersection, a traffic sign can make vehicles slow down rather than speeding through, thereby preventing potential collisions. Moreover, traffic signs are not just for drivers; they also enhance pedestrian safety. For instance, at crossings near campuses where students frequently pass, traffic signals allow pedestrians to cross at appropriate times without having to dodge in and out of traffic. Ultimately, proper signage can significantly reduce the number of traffic accidents, some of which may result in serious injury or even loss of life.
For example, a stop sign indicates that drivers must stop at an intersection to allow other vehicles or pedestrians to safely proceed. A speed limit sign informs drivers of the maximum speed they should not exceed. A yield sign alerts drivers to yield the right-of-way to other vehicles or pedestrians.
