The Moped Riders & Motorcyclists Thematic Report of the European Survey of Road Users’ Safety Attitudes (ESRA) has been published with the active contribution of NTUA, containing a wealth of information on road safety in 39 countries across Europe, America and Asia-Oceania, based on the ESRA3 survey. This Thematic ESRA3 Report describes the frequency of riding a moped or a motorcycle, the use of infrastructure, the road crash involvement, the acceptability of unsafe traffic behaviour, the safety perception of using moped and motorcycle, the rates of self-declared behaviour and factors associated with risky riding behaviours. Furthermore, it includes comparisons among the participating countries as well as results in relation to age and gender.
