Does OSM support Traffic Signs?

How can i show Traffic Signs in map.
and how can i add Traffic Signs to map?

Traffic Signs = Stop Signs, Yield Signs, Speed Limit, Do Not Enter, Handicapped, One Way Si and …

If you search in you’ll find highway=traffic_signals and traffic_signs=*

The question was:

Of course OSM supports traffic signs, but the standard map doesn’t show any traffic sign at all.

I wrote a tool to show any tag, but made a version for traffic-signs also.
Unfortunately, traffic signs are highly country specific so you should adapt my version (it is free for anybody to use/change).

To give you an idea, in this example you see some traffic signs in The Netherlands.
And here is another example.
