This set is targeted at Swedish users wanting to learn the Swedish road signs. The names of the signs are all in Swedish.
The source images and text names were taken from a publication by Vägverket (the Swedish road ministry). I have opted to copy the text verbatim from the publication; you may wish to make adjustments for your own personal use.
"Sveriges vägmärken, trafiksignaler, vägmarkeringar och polismans tecken", published 2006 by Vägverket. Found e.g. on http://www.forarskolan.se/bilder/vagmarken.pdf
Vägverket has disclaimed copyright of the road signs; see the response to Wikipedia.
