Control systems

The fixed toll control stations recognise and record tolling data of the vehicles passing through the cross-section. The vehicle-mounted mobile toll control units perform continuous data collection enabling them to control road-use authorisation anytime, at any point of the toll road network. Based on the data collected, it can be clearly determined if a specific vehicle has road-use authorisation for the given road section.

In order to avoid penalisation, be aware of the following

  • Enter the correct number of axles when you attach or detach a trailer. For example, if you attach a trailer to a two-axle vehicle and now travel with four axles, you must change the J2 number of axles to J4; if you detach the trailer, you must reset the data to J2. Setting the wrong number of axles results in a fine. The number of axles must be set before you begin your journey.
  • Be sure you enter the license plate number and the belonging country code correctly, as the latter, in addition to the plate number, is the other important parameter for the identification of your vehicle, which cannot be changed retrospectively, after you have been fined.
  • Be sure you purchase your route ticket before you begin road use! Route tickets provide authorisation only after payment; a ticket purchased retrospectively for the given road section qualifies as unauthorised road use, which results in a fine. A route ticket purchased for one direction provides road use authorisation only for the planned route, for a one-time journey in one direction. When purchasing your route ticket, please double check whether you have entered your data correctly.
  • You can accomplish your declaration and toll payment more simply and conveniently; however, there are still important things to be aware of. When paying the toll through your on-board unit, before you begin your journey please check whether the unit is turned on, functions correctly, is rendered to the relevant vehicle, and the available balance is sufficient for your journey.

Things to do after you have received a fine (appeal option)

You can easily avoid a fine by observing the rules. If you receive a letter informing you that you have been fined for unauthorised road use and would like to appeal, you can do so with the provisions included in the police letter.


As a result of an important change in the e-toll system for heavy duty vehicles with a gross weight of over 3.5 tonnes, the toll sections designated as detours shall no longer be exempt from toll as of 25 December 2018.

Until the end of 2018, any toll section designated as a detour is automatically exempt from toll. The previous legal provisions did not differentiate between ad hoc and fixed detours, nor was it possible to take into account when someone had already planned to travel on a route that was later designated as a detour.

Considering that in the latter case exemption for the vehicles concerned is not justified, the new legislation eliminates this possibility. At the same time, it also stipulates that in the case of ad hoc detours (in effect for no longer than 31 days), heavy duty vehicles travelling on the detour route shall be exempt from fines even if they have not fulfilled their toll payment obligations for the given road section (i.e. they have not purchased a route ticket or their on-board unit has insufficient balance).

For the time being, the relevant regulations remain unchanged in the e-vignette system, thus no toll shall be paid for the use of otherwise toll sections that the road operator has designated as a detour.
