However, the focus of the European Commission has rather been on lorries than on private cars, as lorries are concerned directly by the internal market. But it was only in the end of the last century, that the legal basis for road tolling was established in Directive 1999/62/EC ("Eurovignette") on European Community level. This Directive had the focus on the tolling of motorways, bridges, tunnels and mountain passes, but only for lorries over 12 tonnes maximum laden weight, and the charging was only possible for infrastructure costs. Eight years later in 2006, the Directive was amended by Directive 2006/38/EC, which has a new focus on road tolling of the trans-European road network, but leaves the EU Member States the right to apply tolls as well on roads not included in the trans-European road network. The amended Directive gives the EU Member States the possibility of varying tolls according to a number of factors such as distance travelled, place, infrastructure type and speed, vehicle characteristics, time of day and congestion level. In addition, the EU Member States are obliged to include all vehicles over 3.5 tonnes maximum laden weight after 2012, and after 2010, the tolls must be differentiated according to the environmental performance of the vehicle.
