On certain routes, or in parts or sections of them included within the interurban public roads, as well as in urban sections, including crossings, temporary or permanent restrictions may be established on the movement of lorries with a maximum authorised mass exceeding 3,500 kgs, vans, joined vehicles, articulated vehicles and special vehicles, as well as vehicles in general that do not reach or are not allowed to reach the minimum speed that could be fixed when, due to holidays, seasonal vacations or mass movements of vehicles, high traffic volume is foreseen, or when the prevailing conditions make it necessary or convenient.

Likewise, for security reasons, temporary or permanent restrictions may be established on the circulation of vehicles in which their own dangerousness or that of their cargo warrants their removal from urban centres, or from environmentally-sensitive areas or from sections such as bridges or tunnels, or their movement outside of peak traffic hours.
