What is road sign dead end?

A dead-end road sign is a traffic sign that indicates that the road ahead is a dead-end, meaning it does not continue beyond a certain point and there is no exit from the road. The sign generally appears at the beginning of a dead-end road, and its purpose is to prevent drivers from mistakenly entering the road and becoming trapped or lost. The sign typically has a black and white color scheme, with a red circle and white background, and may also indicate the distance to the dead-end. Dead-end roads are commonly found in residential areas, rural areas, and off-road areas where the road ends at a cliff or water body. Drivers should always obey the dead-end road sign and turn around to find another route if necessary.
