Final answer:
The exact percentage of fatal and injury collisions caused by failure to yield is not directly provided in the given information.
Step-by-step explanation:
The question pertains to the impact of driver behavior on motor vehicle accidents, specifically how failure to yield contributes to the percentage of fatal and injury collisions. It appears based on the reference material provided that the specific percentage isn't directly stated. However, when considering the overall driver error contributions to fatal accidents, and impacts on health due to traffic collisions, it's crucial to understand that failure to yield is a significant contributor to these statistics, emphasizing the critical nature of adhering to traffic rules to ensure safety.
The primary cause of the percentage of fatal and injury collisions due to failure to yield is 32%.
Driver error, including failure to yield, is a significant factor in traffic collisions, underscoring the importance of following traffic laws.
