It must be borne in mind that the hard shoulder of interurban roads is the place where various types of vehicles travel, such as cycles, mopeds, and animal-drawn vehicles, among others.
If we stop our vehicle on the hard shoulder, we will be obstructing their normal flow of traffic. For this reason, when making a stop or parking, we must do so on the right-hand side of the road, outside the usable part of the hard shoulder.
A distinction must be made between a stop or parking, which is a voluntary manoeuvre by the driver and must be carried out correctly, and an emergency halt (involuntary on the part of the driver), during which, although we must try to stop in the most appropriate place without obstructing other road users, this is not always possible.
