Faculties of drivers of high-priority vehicles

Article 68. Faculties of drivers of high-priority vehicles.
1. Drivers of high-priority vehicles must observe the rules of this regulation, although where assured that they do not endanger any road user, they need not obey the rules of titles II, III and IV, except for orders and signals of traffic officers, which they must always obey.
Drivers of these vehicles may also exceptionally, when travelling along an autopista or autovía in an emergency and not jeopardizing the safety of any user, make U-turns, reverse, travel against the traffic flow on the hard shoulder, use the median strip or emergency crossing areas.
Traffic officers may use or put their vehicles in the part of the road that is necessary when helping other users or traffic. They will also determine in each circumstance the location of emergency service vehicles or other special services.
2. High-priority vehicles include police, fire service, civil protection and rescue, and medical assistance (public or private), in emergency service and whose drivers warn of their presence by means of flashing lights desbribed in Article 173 and sirens described in the RGV.
Exceptionally to the previous paragraph, drivers of the high-priority vehicles may use flashing lights separately without sirens where this does not involve any danger to other users.
3. Infractions of this Article are considered serious offences (LST Art 65.4.c).
