Regarding the shapes and sizes of the Spanish road surface markings, there have recently been some changes.
In this PDF
taken from "carreteros" webpage, in pages 4 to 7 they indicate all the changes from the 1987 normative, and from page 8 there is the whole normative (or in the carreteros webpage here
, so that you can google translate it).
The main changes are:
- The central lane-dividing lines are now 15cm wide instead of 10 outside urban areas.
- In conventional roads (that is, no autovia/autopista nor urban area), the relation of line-void has changed.
- In autovías and autopistas the right border line is now continuous in all cases.
- In roads with three or more lanes with opposing directions, it's obligatory to have double
continous line to indicate overtaking proibition.
- The lines separating an entry/exit lane
are extended towards the border line, until it is 0,10m from it (before there was a bigger gap).
- These arrows
are no longer used to indicate an exit, only these ones
Obviously it will take years before all the roads are adapted to the new normative, but although I think this new normative hasn't been fully approved yet, in the last years they have already done at least some of these changes to newly repaved roads for example. In any case, it's not completely wrong if you use the old normative, it's just to let you know of these changes.
