Final answer:
For passing or crossing situations, it is generally necessary to respond to a signal, such as a traffic or crosswalk signal, to ensure safety and order. Ignoring or disobeying a signal can lead to accidents and jeopardize the safety of everyone involved.
Step-by-step explanation:
For passing or crossing situations, it is generally necessary to respond to a signal. In most cases, traffic signals or crosswalk signals are used to regulate the flow of vehicles and pedestrians, ensuring safety and order. When a signal indicates that it is safe to proceed, drivers and pedestrians should follow the signal's instructions to cross the intersection or road safely. Ignoring or disobeying a signal can lead to accidents and jeopardize the safety of everyone involved.
For example, imagine a busy intersection near a school where many students cross to get to and from campus. Without a traffic signal, these students would have to navigate through traffic, increasing the risk of accidents. However, if a traffic signal is installed, it provides a clear signal to both drivers and pedestrians, indicating when it is safe to cross. By responding to the signal and waiting for the appropriate light or indication, pedestrians can cross the intersection safely and avoid potential hazards.
