I learnt something there!! I didn't realise filtering was illegal in France.
I've been riding through France a couple of times a years for the last 10years and filtering everywhere!
I must admit I don't bother with the headlight mods (it's a fazer), I carry a high viz and my plate has a GB sticker on it, that's about it. I don't carry spare bulbs, breathalysers or have the reflective stickers on my helmet. I seem to remember reading that no one has ever been fined for not having these?
The roads are pretty straight forward, 2 major differences to be aware of:
1. Dodgy roundabouts - they have some which are the same as in the UK, but also some where you have priority coming onto the roundabout but not once you are on it. Or Arc de Triomphe, where you have priority coming on and coming off, but not once you are on the roundabout!
2: Priority Right / "priority a droite" - This image explains it better then I can... basically on some major roads, a car on an adjoining minor road has priority and can pull out on you between these signs. It's worth knowing about!!
