Romania's highway network requires a vignette for all vehicles. You can purchase electronic vignettes (e-vignettes) online or at various points of sale. Your vignette is linked to your license plate number. Keep your proof of purchase and double-check that your license plate number is entered correctly to avoid fines. Vignettes are available for various durations, such as daily, weekly, monthly, or annual. You can verify your vignette status online using your license plate number.
