I finally got arund to applying to exchange my UK driving licence for a Spanish one. That was on 7th June and since then I've heard nothing.
So the question is how long does it normally take traffico to process this?
Also is there any way that I can check the status of my application?

I exchanged mine 4 years ago and it took about 3-4 weeks. They should have given you a "temporary" paper stating that you're in the process of exchanging, just in case you get stopped by traffico.
The delay could also be due to the fact that in August Spain closes down for holidays!
All the same, it might be worth contacting the office dealing with your licence.

Expect a minimum of one month then should appear in the post. Maybe add a bit more for August .

Mine took around 6 months from traffico in Sevilla

It seems that I've been impatient, I bumped into a fellow Brit this morning and he told me that his took 6 months to come through. Guess that I'll just have to wait.
