What action should a driver take when they see a "Do Not Enter" sign?

When a driver sees a "Do Not Enter" sign, it is a clear indication that they are not allowed to proceed in that direction. This sign is typically placed at one-way streets or on roads where entering would lead to hazardous situations. Recognizing this sign means the driver must understand that they need to avoid that particular roadway altogether. Proceeding with caution, entering only if no cars are coming, or making an immediate U-turn does not address the underlying rule that the area is off-limits to entering vehicles. Instead, identifying that they cannot go that way ensures the driver adheres to the traffic regulations, helps maintain safety, and prevents potential accidents or traffic violations.
