Priority vehicles is one of the topics in the Priority block of the Spanish DGT theory. Who goes first: right-of-way rules at junctions, roundabouts, narrow sections and special cases. Understanding this section well helps you answer the theory-exam questions on this topic with confidence.

In simple terms, this point of the DGT theory establishes that the installation of flashing lights and special acoustic warning devices on priority vehicles must require authorization from the corresponding Provincial Traffic Headquarters, in accordance with vehicle regulations.

Priority questions use concrete situations (junctions, roundabouts, narrow sections): first work out who has right of way and why.
