The use of a dedicated toll sticker is fundamental to the operational efficiency of toll collection across Croatian motorways, particularly given that the country continues to utilize a closed toll collection system. According to the Croatian Highways (HAC), this sticker serves a critical function by precisely recording the point of vehicle entry onto the motorway network. The system’s reliance on this marker is absolute: without the physical sticker indicating the entry location, the automated tolling infrastructure cannot accurately ascertain where the driver began their journey on the motorway.
This lack of verifiable entry data disrupts the standard toll calculation process. Consequently, when a vehicle cannot be properly identified via the standard entry mechanism, the HAC must resort to an alternative procedure. This alternative involves initiating a specialized toll collection process.
This fallback method is strictly governed by the detailed rules and general conditions established by the HAC. In essence, the sticker acts as the primary digital receipt of ingress. Its presence ensures that the tolling system can calculate the precise distance traveled and bill the correct amount, thereby maintaining the integrity and reliability of the national motorway toll revenue stream.
Adherence to the sticker requirement is therefore not merely procedural, but integral to the functioning of the entire toll collection framework.
