Its the same with all French rules/laws they do not apply to the French as far as they are concerned, but they apply to everyone else. I've just got back from France with a M/home, everything you read concerning "Blind Spot" stickers on vehicles over 3.8T you must have them or face 132 Euro on the spot fine. Most of the M/homes non French had them but not the French its their right not to disclose if their M/home is 3.8T as they will end up as class 2 on the tolls?
