Stopping or parking, as a general rule, must be carried out: - On urban roads: within the carriageway and the hard shoulder, even if it is passable, provided that a clear space of at least 3 m is left. On both sides if the road is one-way, and only on the right-hand side if the road is two-way. - On interurban roads: outside the carriageway and the passable part of the hard shoulder. Always on the right-hand side even if the carriageway is one-way.
