This textbook aims to sketch out the main problems arising in the field of EU transnational transportation by providing adequate understanding of the legal setting in the five key EU legal areas for this sector: fundamental freedoms, private international law, posting of workers, social security coordination and social dialogue. Indeed, road transport is a truly living organism which makes it challenging for the laws to keep up with its ongoing dynamics. In addition, due to its inherent transnational element, the process of application of relevant laws is often shrouded in ambiguity, making it difficult to solve the emerged conflicts of laws. Against this background, this textbook provides an integral vision on the interaction of EU freedoms with social rights at EU level offering a comprehensive and unique in- depth coverage of the most relevant topics and presenting nuanced guidance depicting problem solving skills which was carefully selected by the leading academic experts. Overall, this position is addressed to not only academics but also to students, practitioners and others interested in the road transport sector.
