The rapid growth of platform-based delivery services has raised concerns about commercial motorcycle safety, particularly regarding the interplay between occupational pressures and age-related risk factors. A critical gap remains in understanding how age moderates the relationships between occupational pressures (time pressure and fatigue) and risk-taking patterns. This study examines these relationships among commercial motorcycle riders, comparing young (under 35) and middle adult (35 and older) groups. Data from 1,884 riders across five regions of Thailand were analyzed using structural equation modeling with measurement invariance testing. Results revealed significant age-based differences: middle adult riders exhibited stronger effects of time pressure on risk-taking behaviors, whereas young adults showed a substantially stronger link between general risk-taking tendencies and comprehensive risk-taking behaviors. Time pressure’s impact on fatigue was more pronounced among young riders. The findings support age-specific interventions for training, monitoring, and support systems in platform-based delivery services.
