On-Board Unit Blocking
If the OBU in the pre-paid toll regime is signalling a low balance of pre-paid toll, increase the pre-paid toll amount without any delay at the nearest Customer Point. The OBU 1374 signals the low pre-paid toll balance by the first button flashing green and by an acoustic signal at the same time. The OBU Sitraffic Sensus Unit and Billien OBU 5010 indicate the low pre-paid toll balance by the flashing € symbol together with the flashing position LED indicator and an acoustic signal at the same time. When the pre-paid toll balance reaches EUR 0, the OBU will be blocked.
Similarly in the post-paid toll regime the first button on the OBU 1374 and on the OBU Sitraffic Sensus Unit and Billien OBU 5010 the € symbol combined with the flashing position LED indicator start to flash if the total amount travelled gets close to the amount of the bank guarantee or cash deposit. This warning serves as information for the operator/vehicle driver that the amount of the bank guarantee or cash deposit should be increased.
If failing to pay the Toll and/or other liabilities even within 3 calendar days from the due date the System Operator is entitled to block all the On-Board Units of the Vehicle Operator being in delay with the payment of Toll and other liabilities, while every blocked On-Board Unit indicates the blocked status to the Vehicle Operator and/or Driver.
