In cars, the vignette must be affixed on the inside of the windscreen so that it is clearly visible from the outside. It is important that it does not obstruct the driver’s view. In the case of motorbikes and trailers, the vignette should be affixed to an easily accessible part. Never attach it with adhesive tape or film so that it is easy to remove and transfer to another vehicle. You could be fined several hundred fines if the police catch you.
