Research from 2009-2012 indicates that what percentage of crashes were due to rider error?

The correct choice indicates that 69-70% of motorcycle crashes during the period from 2009 to 2012 were attributed to rider error. This high percentage emphasizes the critical role that a rider's actions and decisions play in motorcycle safety. Factors contributing to rider error can include inadequate training, poor judgment, failure to recognize hazards, or not adhering to safety protocols such as wearing appropriate gear or maintaining proper control of the motorcycle. Understanding that such a large proportion of crashes is linked to rider error highlights the importance of education, training, and adherence to safety practices for motorcyclists. This knowledge can lead to improved rider awareness and potentially reduce the number of accidents on the road. The other percentages are lower, suggesting a lesser impact of rider error in crashes, which does not align with this significant data point.
