Pothole
The number of potholes that appear in any particular stretch of roadway largely depends on the type of pavement used. Surfaces that absorb less water are generally less susceptible to the problem.
Potholes can reach feet in width, though they usually only become a few inches deep, at most. If they become large enough, damage to tires and vehicle suspensions can occur.
