The COVID-19 outbreak is having a major impact on European transport and mobility. It has caused massive negative demand shocks due to the necessary containment measures along with the voluntary efforts to practice social distancing, minimize commuting and avoid travel. These have led to supply chain disruptions, steep decrease in foreign and domestic tourism, and overall reduced mobility. EU State aid rules and transport legislation enable Member States to support undertakings affected by the outbreak, including those in the transport sector.
