The primary Incident Type for the 30 crashes is summarized in Table 2. The most common case was a ground impact at low speed, which is defined more fully in the data dictionary as “…two-wheeled vehicle falls coincident with low or no speed (even if in gear), due to issue not defined in other Incident Type categories. The rider allows the bike to lean while it is being stopped, just beginning to move from a stop, or making a turn at low speed. Vehicle upright stability is lost due to lack of input by the rider to counteract the effect of gravity.” (Williams, McLaughlin, Williams, and Buche, 2015).The low-speed (“capsize”) crashes are a unique dataset that is not found in traditional crash studies. Though they occur at low (or negligible) speed, they are events that are important to riders. They also have the potential to reveal a breakdown in rider task execution, baseline proficiency, or a temporary reduction in readiness to ride (e.g., fatigue and attention) that could result in problems during a continued ride. These low-speed “crashes” appear to be relatively typical among everyday riding, and are included in the risk analysis. They are events that riders want to avoid, and their analysis provides a basis for continued exploration and categorization of all motorcycle incidents.
