The National Road Company has set up 110 video cameras on national roads and highways to check the validity of the vignette.

CNAIR has implemented an automated system with 110 video cameras on national roads and highways to identify vehicles driving without a valid registration sticker. The cameras photograph license plates and a software program compares them with the national database. If a car doesn't have a paid license plate, an alert is issued and a police officer will check and fine the owner. Also, since September, charges for vignettes have increased and prices are set in euros, fluctuating according to the exchange rate.
