Step-by-step explanation:
The question refers to fluorescent pink signs with black lettering, which are known as temporary traffic control signs or incident signs. These signs play a crucial role in road safety by informing drivers about unexpected conditions such as road closures, detours, or hazardous situations. They are deployed in response to road user incidents, natural disasters, hazardous material spills, or other unplanned events that might affect the flow of traffic. Knowing the meaning of such signs is essential for safe driving and for complying with traffic laws.
Another important aspect of road safety is the installation of traffic signals. The primary reasons for installing a traffic signal include excessive speeding, frequent accidents, and pedestrian safety. A properly installed traffic signal can make vehicles slow down, hence reducing the likelihood of speed-related accidents. It also provides pedestrians with a safe time to cross, enhancing their safety, particularly in areas with heavy foot traffic, such as near campuses.
