Final answer:
An orange sign alerts drivers to potential hazards and the need to slow down or stop. Traffic signals can significantly improve safety by controlling vehicle speeds and safety at intersections, especially for pedestrians near school campuses.
Step-by-step explanation:
An orange sign on the road is a clear indicator to drivers that they should be extra alert, adjust their speeds, and be prepared to make a full stop if necessary. These signs are often in place to ensure safety in areas where unexpected conditions or changes in the flow of traffic might occur. For example, this type of signage is crucial near intersections where vehicles often speed through without regard for the posted speed limit. The introduction of a traffic signal at such intersections can greatly reduce the likelihood of accidents by controlling the flow of both vehicular and pedestrian traffic. This is particularly important in zones of high pedestrian activity, such as near school campuses, to allow individuals to safely cross without having to navigate through moving vehicles. From a safety standpoint, the enforcement and respect for traffic signs and signals are critical—as heightened accident rates and tragic incidents have highlighted the need for better traffic control measures.
Pedestrian safety is also a significant consideration when installing traffic signals. Students and other individuals who need to traverse busy intersections will benefit from the ability to cross at designated times without risking their safety. Last but not least, on top of these general safety reasons, empirical data showing a spike in traffic accidents, with some resulting in fatalities, provide a compelling argument for the installation of a traffic signal.
