You can tag the sign as "city_limit". It's a nice thing for rendering
but be warned that it is completely useless for navigation.
(For the later a polygon (e.g. place=*)describing where the city-limits are
in all
 directions are needed as opposed to mapping the location of some
 signs on some roads that leave the city for various reasons.)
Also keep in mind that there are 3 different city-limits.
* where traffic is considered "inside a build-up area" (navigation)
* where postal addresses contain to that city (searching)
* where the outermost buildings end. (rendering)

It has been discussed at length before. Please consult the archive
first.
