Nikolaou D., Kaselouris K., Yannis G., “Risky Behaviours and Safety Perception of Moped Riders and Motorcyclists Globally”, Proceedings of the 12th International Congress on Transportation Research (Thessaloniki, Greece, 16-18 October 2025).

Motorcyclists and moped riders are among the most vulnerable road users globally, facing elevated crash and fatality risks. This study, based on the third edition of the E-Survey of Road Users’ Attitudes, examines the self-reported behaviours of over 6,000 riders from 39 countries. Common risky actions include speeding, riding without a helmet, and riding under the influence of alcohol, drugs, or distractions like social media, with younger and male respondents more likely to engage in these behaviours. Notably, 20%-40% of riders reported helmetless riding, and nearly half admitted to speeding outside built-up areas in the past 30 days. Generalized Linear Mixed Models revealed that those viewing risky actions as acceptable were significantly more likely to engage in them. Gender, age, and residential environment also played critical roles, with younger, male riders consistently exhibiting higher risk-taking. Conversely, support for stricter enforcement and legal obligations correlated with safer self-reported behaviours.
