Drivers of priority vehicles must observe the principles of this regulation, although, provided they have ensured that they do not endanger any road user, they may fail to comply subject to this being at their own responsibility, except for the orders and signals of police officers, which are always mandatory.

Likewise, they will determine in each specific case the places where emergency services vehicles or other special services should be positioned.
