Every day, more than 400,000 truck inspections are being done  on the correct compliance with the kilometer charge. This means that every truck is checked three times a day on average.
The authorities have three ways of controlling the vehicles:

– Via fixed gantries on the main roads, equipped with cameras and license plate recognition.
– Via movable control cameras
– Via control vehicles managed with control officers

In case of a violation of the kilometer charge, the regions can issue an administrative fine ranging between 100 and 1,000 euros, depending on the severity of the violation.
