From 1 January 2019 new tariffs for the truck toll will apply in Germany. According to the recently passed 5th amendment of the German Federal Trunk Road Toll Act (BFStrMG), the weight class is a parameter for calculating the toll amount. Soon the toll rate per kilometre will be composed of three partial toll rates: infrastructure costs corresponding to the weight class of the vehicle or vehicle combination subject to toll, the air pollution costs incurred, depending on the emission class of the vehicle, and the costs for noise pollution of 0.002 euro per kilometre.
Since summer 2018, the weight classes have been displayed on the On-Board Units (OBUs). From 1 January 2019, truck drivers must correctly set the weight class as part of their duty to cooperate. The weight shall be classified in the following weight classes: equal to/greater than 7.5–11.99 tonnes gross vehicle weight (GVW), equal to/greater than 12 to 18 tonnes gross vehicle weight and greater than 18 tonnes gross vehicle weight. From a gross vehicle weight of over 18 tonnes, up to 3 axles or 4 or more axles are additionally distinguished, which the truck driver must specify in the On-Board Unit. It is also possible for vehicles and vehicle combinations up to 18 tonnes gross vehicle weight to set the number of axles. Motor vehicles under 7.5 tonnes gross vehicle weight are not subject to toll.
To determine the gross vehicle weight of vehicle combinations, the gross vehicle weight of individual vehicles is added, contrary to the German Road Traffic Registration Regulations. Support and fifth-wheel loads are not included.
