A mountable curb is a type of curb that has a slight dip on one face of the curb so that vehicles can drive over them easily without damaging tires and wheels. These curbs are preferred at openings for pedestrians with shopping carts or strollers, and those who are on bicycles or roller-skates to cross safely on or off the sidewalk. Mountable curbs are most often found at the end of driveways or in small parking lots.
