The E-Scooter Riders Thematic Report of the European Survey of Road Users’ Safety Attitudes (ESRA) has been published with the active contribution of TIRF and 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 provides an in-depth examination of road safety issues associated with e-scooter, including an extensive analysis of self-declared unsafe behaviours in traffic, the utilization frequency of e-scooters, and the incidence of involvement in road crashes among e-scooter riders. Moreover, the Report investigates determinants that may elevate the risk of crash involvement for e-scooter riders, offering a detailed perspective on the complexities of e-scooter road safety. Unsafe self-declared behaviors among e-scooter riders are influenced by demographics, attitudes, and experiences, with women and older individuals less likely to engage in risky actions like riding under the influence or crossing on red lights, while students, those with permissive attitudes toward traffic laws, and individuals involved in e-scooter crashes are more likely to exhibit unsafe behaviors.
