We're heading to France (Brittany) in 10 days. Last time we went, 4 years ago, different car, we dutifully got and applied those sticker things you're supposed to put on your headlights- but noted no one else pulling off the ferry appeared to have bothered. Did they all troop to their garage and get their lights adjusted? Or spend ages with their lights pointing at a wall going 'up a bit/down a bit' - or did they just ignore it??
But we do have the triangle and hi-viz vests!
