Activities that affect traffic safety is one of the topics in the General rules block of the Spanish DGT theory. Defines who the traffic rules apply to and where, the basic definitions and the principles behind the whole theory. 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 no device, installation or construction must be installed on roads or land subject to the scope of application of the legislation on traffic, motor vehicle circulation and road safety, nor must any actions such as filming, surveys or tests be carried out, even on a provisional or temporary basis, that may hinder traffic.

The exam often asks where and to whom these rules apply; read the options carefully, as they frequently change a single word.
