HOW TO PAY TOLLS IN GERMANY
All trucks with a gross vehicle weight over 7,5 t have to pay the Toll Collect. It is a kilometer tax, the toll charges are based on the distance travelled on the toll road, the number of axles on the vehicle and the Euro emission class.
TollCollect technology is designed to support other tolling systems, TOLL2GO service implemented in cooperation with the Austrian toll operator ASFINAG. With TOLL2GO, the toll for trucks with weighting 12 tonnes or more can be paid in Austria using the TollCollect On-Board-Unit.
VIALTIS registers you on the Toll Collect System as «Payment method with payment guarantee» mode so you won't need to pre-pay your trip.
You can install the OBU with the Toll Collect agreed Service Partner as soonas you get the email confirming the vehicle registration.
