If you know what's good for you ...
The problem with priorité a droite is that signage is rare. I'd be a lot more comfortable with the rule if the junctions were all explicitily marked, but few are. The first junction I provided a link to is, by a small cross 100 metres before (that you'll probably miss if you're not looking for it):

The second one never used to be, but in the last couple of years is now marked with a line in the road. The third is the more typical case, no sign at all. Go backwards as far as you like, but you'll see no warning at all.
