What percentage of all fatal crashes occur in a speed zone of 55 MPH or more?

1. 45%

2. 50%

3. 60%

4. 65%

The correct answer is: 65%

The correct answer indicates that 65% of all fatal crashes occur in a speed zone of 55 MPH or more. This statistic reflects a significant correlation between higher speed limits and the severity of crashes. It is important to understand that higher speeds reduce the reaction time for drivers and increase the kinetic energy involved in collisions, resulting in more severe outcomes. This understanding aligns with traffic safety studies that indicate as speed increases, the likelihood of fatalities in crashes rises dramatically. Additionally, driving at higher speeds often results in less time to make critical decisions, contributing further to the risk of fatal outcomes. In contrast, the other percentages reflect a smaller proportion of fatal crashes occurring at lower speed zones, highlighting that while all speed zones can be dangerous, those at 55 MPH and above present a heightened risk factor. This data is vital for policymaking around speed limits and for educating drivers about the dangers of high-speed driving.
