| Abstract | Thailand faces a significant issue with motorcycle use, with over 22 million registered vehicles in 2023, accounting for 51% of all registered vehicles. Motorcycle crashes account for 80.4% of road traffic fatalities, with the highest death rate among ASEAN countries. A study aims to examine the relationship between rider characteristics and actual riding behavior, and to assess what risk behavior factors were associated with self-reported crash involvement and fine offenses. This study focuses on the risk behavior, aggressive behavior, and risk perception of young motorcyclists in Thailand using focus groups and questionnaires. The questionnaire consisted of four main sections: personal, vehicle, and riding information, self-reported crash involvement and fine offenses, perception of unsafe riding behaviors, and riding behaviors.Data analysis was performed using the STATA program, including descriptive statistics, principal component analysis, Pearson's correlation coefficient, multiple linear regression, and binary logistic regression. The study found that 70% of young riders under 18 use motorcycles over the legal engine size, often report unsafe modifications, and lack proper licenses. Most riders use rear-heavy braking due to misinformation or lack of proper riding knowledge. Young riders are more likely to engage in speed-related risky behaviors, such as rider anger, unsafe surfaces, and unhelmeted passengers. They also reported higher traffic errors, speed violations, stunts, and safety violations. Young riders also reported higher aggression scores, indicating greater emotional reactivity and impulsive behavior. They were more likely to report crashes and near-crashes than adult riders, with higher speed violations and past traffic fines. Young riders aged 18-24 were more likely to report fines than adult riders. |
