The hard shoulder of interurban roads is the area designated for the circulation of certain vehicles, such as mopeds, cycles, or vehicles for people with reduced mobility, among others. For this reason, if we park or stop on the hard shoulder, we will obstruct their movement. Therefore, on these roads, vehicles must always stop or park off the carriageway and off the passable part of the hard shoulder. Stopping on the hard shoulder is permitted if it is not passable. Additionally, it must always be done on the right-hand side, regardless of the direction of traffic.

On urban roads, hard shoulders are normally used for parking, so they may be used for stopping and parking even if they are passable. If the road is one-way, stopping may be done on either the right or the left; if it is two-way, only on the right.
