OBU Manual
6 Toll service specifics
Changeable OBU parameters (Overview)
Toll charger and toll service specific requests require to enter and update certain data on the OBU. This might
lead to differing OBU displays. Depending on special regulations of a tolling system, the number of axles and
the current gross train weight (GTW) must be entered seperately by the driver with regards to the current
vehicle train. As part of the self-declaration obligation, the driver is responsible for the correctness of this
information.
Before start of a drive, the driver has to verify the conformity of OBU and vehicle. The driver always has to
update the number of trailer axles on the OBU after coupling or uncoupling a trailer.
The following table shows which data and toll services are concerned, and which OBU startup screens will
appear depending on the chosen toll service:

Explanation
Axles: the current, actual total number of axles for
the vehicle combination (tractor unit + trailer) is
displayed (here: "3"), which may differ depending
on the attached trailer. Therefore the trailer axles
must be specified separately by the driver via the
OBU.
Weight: The new, gross train weight must be
updated, when attaching a trailer to the tractor
unit. The current gross train weight (GTW) is the
maximum permissible combined weight of the
tractor and the currently attached trailer.
When selecting the weight range via the OBU
menu, e. g. 7.5t and <12t, the lower value will
be displayed on the OBU screen.
No specific driver input necessary.
No specific driver input necessary.
For Belgium, the maximum permissible gross
weight for the vehicle combination according to
the vehicle certificate is already stored in the
system during vehicle registration and is
automatically displayed on the OBU screen, e. g.
11.8t.
No specific driver input necessary.
