Road transport enjoys two definite major advantages: its flexibility and its capacity for carrying goods door to door. It plays a direct role in developing the European internal market and the more this market opens up and becomes unified the more the road transport sector benefits from this development by opening up and unifying at the same time. Hence, there is a need for efforts towards harmonising the rules and regulations. Moreover, road transport also has to meet challenges connected with its success: network safety and saturation, impact on the environment. The future of road haulage... should therefore be viewed in the framework of an overall medium-term vision of the Union's transport policy as analysed in the White Paper published on the subject in 2001.
