Inspection and fines
The Police of the Czech Republic and the Customs Administration of the Czech Republic can tell by the vehicle's number plate whether you have a valid electronic highway stamp or whether your vehicle is exempt. The check is carried out directly on the tolled section of the highway by means of patrol vehicles equipped with a camera system for recognizing the number plate and with the help of a remote connection to control gates or control at rest areas and parking lots.
Amount of fines: A driver detected by the system on a tolled section of the highway without a valid electronic highway stamp (and if he is not exempted) faces a fine of up to CZK 20,000. The control will also cover possible misuse of the exemption. If a natural or legal person submits an exemption notice without being entitled to it, in an attempt to deliberately abuse the system, the fine can rise to CZK 100,000. If the tolled section of the highway is used by a vehicle to which the exemption applies, but the driver has not filed the exemption notice, even though the law requires it, he faces a fine of up to CZK 5,000. Those who do not report to the State Transport Infrastructure Fund within ten working days that the grounds for exemption have passed are threatened with the same amount of fine. What will happen to the obtained data and photos?
In addition to scanning the vehicle's number plate and subsequently finding information about the validity of the electronic highway stamp, a photo of the vehicle is also taken if the vehicle does not have a valid electronic highway stamp or is not exempt. Immediately after the picture is taken, the software divides the recording into a photo and data. Furthermore, it only works with data that is sent to the control system.
