Hi Colin,
bienvenu and welcome in this forum. I am german and live a third of the year in Brittany/Bretagne near Morlaix, I wear no helmet and have no license plate in front of my Dreirad (this is the german law). A lot of french threewheeler drivers don't speak english, so perhaps you ask in this french forum:
