Which type of warning sign indicates a potential hazard?

Warning signs are specifically designed to alert individuals to potential hazards that could pose risks to health or safety. These signs often use bright colors, such as yellow, and symbols to convey a sense of caution. Their main purpose is to inform people of situations that might lead to injury or other hazardous conditions, prompting them to take appropriate precautions.

In contrast, instruction signs typically provide guidance on procedures or tasks, while information signs serve to present general information and may not indicate any danger at all. Prohibition signs, on the other hand, specify actions that are not allowed in a given area, highlighting rules rather than potential hazards. Therefore, the defining characteristic of warning signs is their focus on alerting people to imminent risks, making them essential in maintaining safety in various environments.
