Facing increased pressure from freight traffic passing through and needing an additional source of revenue for motorway maintenance and expansion, in January 2005 Germany implemented a distance-based toll for all lorries of more than twelve tonnes gross weight (later reduced to 7.5 tonnes) using the motorways (Autobahnen).
The German government paid for the approximately 450,000 OBUs currently in use and lorry drivers were responsible for covering their installation (UK Commission for Integrated Transport 2007).
In addition Federal Officers of Freight in 300 mobile enforcement vehicles patrol the motorways and are authorized to pull lorries over and check for payment records.
Toll revenues in excess of system operating costs provide funding for transport infrastructure improvements (Richards, 2006).
The UK Commission for Integrated Transport (2007) cites a 6% decrease in the number of empty runs and a 6% shift to rail from road freight mode as a result of implementing the system.
The only negative consequence of the freight toll system detected thus far has been the rerouting of some trucks off the motorways onto other roads, resulting in additional noise and congestion on those routes.
