Are you an EU citizen and have the blue badge? If so, you can check: http://ec.europa.eu/.../files/parking_card_leaflet_en.pdf

Thanks for sharing this info Bea Beat. I agree, the information online is not 100% clear. We arrived in Prague yesterday and fortunately the place where we are staying has a reserved car park for us.
It has been a good excuse to test the local tram of Prague.. which was also a bit confusing.. but in the end we made it :D .
Did you have yourself any experience using the public transportation over here?

 I had not read the part related to CZ. I am very puzzled. Check this: http://www.disabledmotorists.eu/.../czech_republic.htm and this: http://europa.eu/.../parking.../czech-republic/index_en.htm . The weird thing is that two sources are both from Europa.eu, but still they provide different info

Thank you Bea. Yes, are EU citizen with a blue badge.
I noticed that leaflet, but I am not sure what they mean with badge 01.. It's only mentioned in the Chech Republic paragraph.

We used the blue badge in CZ (but not in Prague) to park in the disabled parkings. But we always paid since we were not sure if we should pay or not. We were not fined, but who knows - maybe we were just lucky?

yes, I worked in Prague, back and forth, for almost 2 years. My partner (he is the one with the wheelchair, I am able bodied) visited me several times. We used trams a lot - in the timetables you can read which tram is accessible (on average one out of two). We never used the metro together because many stations are not accessible. Prague is quite small and trams are very efficient, so we did not really need to use the metro. If you need any info, just ask, I'll be glad to help if I can.
