This includes changes in traffic patterns, the presence of workers, equipment, uneven surfaces, or detours. Recognizing this type of sign is critical for maintaining safety, as it signals that extra caution is necessary. It prepares drivers to slow down and stay alert to any unexpected situations, ensuring they navigate through the area safely.
