Although it may seem like a rhetorical and very simple question, it is one of the most common questions on DGT theory exams and one of the most common failed questions.
In fact, the Directorate-General for Transport recently posted this question on social networks so that followers can check their level of knowledge of the Highway Code.
That the discontinuous lines of a road, technically discontinuous longitudinal markings, are longer or shorter is by no means the result of an accident, it is not even the result of an error on the part of the operator operating the painting machine, but rather there is an answer and much more elaborate meaning .
On motorways and expressways, these lines must be 5 meters long and 1.5 meters wide and spaced 12 meters apart. On conventional roads, the same lines must be 4 meters long with a distance of 8.5 meters between them.
This type of marking is intended to delimit the lanes while offering the possibility of crossing them to carry out maneuvers such as overtaking.
When these lines are double and symmetrical, it is most likely that we are at an intersection or on a turning lane, two of the situations in which this mod is used.
In the event that the lines of the discontinuous line lengthen until they almost touch, it means that the line is about to become a continuous line that is about to appear.
Conversely, when the lines become shorter and separate, they indicate the arrival of a hazard that requires our attention, be it a crosswalk, a careful transition, a sharp turn, a change in altitude or the entrance to an area where it is normally there are car retentions. By the way, the correct answer is B.
