Caution signals are indicators that suggest potential danger or the need for careful attention. These signals can be visual, such as warning signs or colored lights, or auditory, like alarms and sirens. They are designed to alert individuals to take precautions and avoid risky situations, ensuring safety in various environments, including roads, workplaces, and public spaces. In many cases, caution signals are standardized to ensure universal understanding. For example, the yellow traffic light signals drivers to slow down and prepare to stop, while hazard signs in construction zones warn of possible dangers. Recognizing and responding to these signals is crucial for maintaining safety.
