The e-vignette is entirely digital, tied to your plate — nothing to stick on the windscreen. Most of the motorway network runs a normal 130 km/h, but one signed stretch allows up to 150.
Nothing to display; ANPR cameras check your plate against the registry.
The 10-day option is the practical floor for anything longer than a weekend.
The 150 km/h section is signposted explicitly — the default motorway limit elsewhere is still 130.
