A pothole is an irregular-shaped, shallow hole or crack in the roadway surface. Its bottom is easily visible and it may be partially filled with mud, dirt, or loose gravel. The highway surface around the pothole is level.

If the defect is deep or hollow or it's located next to a catch basin, it is considered a cave-in, not a pothole.

A cave-in is a collapse of the roadway surface in which the pavement has cracked apart and fallen into a deep empty space without a solid bottom beneath the surface. Large pieces of pavement can be seen in the hole. The edges of a cave-in are usually jagged and the surrounding roadway surface may be sunken.
