Slovenia uses a highly efficient, multi-layered monitoring system:
- Stationary Cameras: High-speed cameras are mounted on gantries over the motorways. They scan every license plate and cross-reference it with the DARS database in milliseconds.
- Mobile Units: DARS toll enforcement vans and police cruisers patrol the highways. They are equipped with mobile scanning technology that checks plates of vehicles in moving traffic.
-
Height Sensors: The cameras also include sensors that measure the height of your vehicle over the front axle to ensure you aren't using a cheaper Class 2A vignette for a larger Class 2B vehicle.
