Speed ​​reduction

Speed ​​reduction is one of the topics in the Vehicle movement block of the Spanish DGT theory. How vehicles must move on the road: direction of travel, position on the carriageway, speed and distances. 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 except in cases of imminent danger, every driver, in order to significantly reduce the speed of his vehicle, must ensure that he can do so without risk to other drivers and must warn them in advance in the manner provided for in Article 109, without doing so abruptly, so as not to cause a risk of collision with vehicles travelling behind his vehicle.

Questions here combine speed, lane position and distances: always check whether the road is urban or interurban.
