I'm getting in a bit of a pickle with my Euro road trip of what I do and don't need with clean air stickers. Motorway stickers etc.
So need as much help as to what I do and don't need
We are traveling through
Brugges, Brussels, Luxembourg, Germany-Stuggart-Austria-Salzburg-Kitzbuhel, Italy-Venice-Lake Como, Switzerland- Zermatt, France- Lake Annecy- Bourne- Paris- Lille, Home
The more I look into the more confused I get about all these stickers etc.
Anyone that's travelled and can help would be a massive help
