So I’m planning a road trip across a few countries this summer and heard you need these digital highway vignettes now instead of stickers, which is new to me. I’ve never bought one online before and all those random sites popping up have me worried I’ll get scammed or fined halfway through the trip. I’d love advice on the best legit places to buy them, any red flags to watch out for, and how the whole process works (like how do you check you actually have a valid vignette?). Anyone with recent experience in 2026, please help me out!
