Are you sure you have everything in the car that you need?
You need disposable breathalysers for France and/or Belgium
High vis, triangle etc along with spare bulbs all by law
We got pulled on one of the trips and actually got serious grief for German style plates
They also checked for all the above
You’ll get away without the headlight stickers I’ve never used them once on 6 big trips across

What routes to Europe are you taking?
Tolls in France are a pain in the bollocks
