Traffic restrictions

Article 39. Traffic restrictions.
1. Subject to the arrangements in the following sections, temporary or permanent limitations of traffic may be established on roads subject to the RGC, when required by conditions of safety or traffic flow.
2. For certain routes or sections of them classed as interurban public roads as well as in urban sections including travesías, temporary or permanent restrictions on vehicles with a MAM over 3,500kg, vans, articulated vehicles, vehicles and special vehicles, as well as vehicles in general that cannot achieve or are not allowed to travel at the minimum speed may apply, when, because of festivals, seasonal vacations or massive vehicle traffic, high traffic density is anticipated, or when conditions make it necessary or advisable.
Also for safety reasons, temporary or permanent traffic restrictions may be applied to vehicles for reasons where danger exists or the nature of their load advises avoidance of urban centres, environmentally sensitive zones or particular sections like bridges or tunnels, or their transit outside of times of high traffic density.
3. The restrictions alluded to are the responsibility of the competent authority.
4. In all cases, any restrictions will be published at least eight working days in in advance in the BOE and where applicable in the regional government equivalent.
Exceptionally, when it is considered necessary to improve traffic flow or safety, traffic officers may temporarily impose restrictions by appropriate measures.
5. In case of recognized urgency special authorizations may be granted for vehicles using routes that are subject to restrictions. Prior justification of the absolute necessity to travel by such routes and during periods subject to restrictions must be demonstrated.
These special authorizations will specify the vehicle registration and basic characteristics of the vehicle covered, the goods, the roads affected and any other conditions applicable.
6. Authorizations are granted by the authority that imposed the restrictions.
7. Traffic restrictions in this Article are independent and they do not exclude those imposed by other competent authorities.
8. Travelling on restricted roads without the authorization in paragraph 5 is an offence (LST Art 67,2).
