The UN Road Safety Collaboration organised with great success the global campaign for the Sixth UN Global Road Safety Week, with was held on 17-23 May 2021. The 6th Global Road Safety Week will have as theme Managing Speeding, with focus on city streets safety and the introduction of 30km/h speed limit in cities. It was a great opportunity to mobilise the global population (Authorities, stakeholders, citizens) and launch the global plan for the proclaimed Second Decade of Action for Road Safety 2021-2030. During that week, several road safety events were organised worldwide, including the active participation of NTUA.
