Cognitive aspects play a crucial role in inciting motorcyclists to perform risky riding behaviors. Unfortunately, research on the contribution of scripts as a cognitive factor that facilitates decision making related to riding behavior is lacking. Through two studies, the current research attempted to investigate the roles of different expected events within a rider’s script that lead to risky riding behaviors, particularly lane-splitting, dangerous overtaking, and wrong-way riding. In Study 1, an interview was conducted with motorcyclists to identify the elements in a rider’s script that relate to lane-splitting behavior, dangerous overtaking, and wrong-way riding, within the contexts of both pro-risk and anti-risk riding situations. Subsequently, in Study 2, a survey was administered to motorcyclists to determine the elements of a script with the strongest bearing on a rider’s decision to perform lane-splitting, dangerous overtaking, and wrong-way riding. Findings from Studies 1 and 2 suggest that in certain riding situations, estimates of distance and width of gap between vehicles are the primary script elements with the greatest weight of importance in lane-splitting and dangerous overtaking. With regard to wrong-way riding, road situation and condition, as well as police presence, were the script elements found to have the greatest weight of importance in the performance of the behavior. Based on these results, the intervention for reducing risky riding behavior should use a different approach based on the nature and conception of each risky riding script.
