What was the trend in the crash fatality rate in Nevada between 2009 and 2013?

The trend in the crash fatality rate in Nevada between 2009 and 2013 showed a consistent improvement each year. This indicates that the state implemented effective strategies and policies to enhance traffic safety, possibly through increased law enforcement efforts, public awareness campaigns, and improved road conditions. These measures would have contributed to reducing the number of fatal accidents over time, reflecting positively on the state's commitment to enhance driver education and awareness.

In contrast, the other options suggest scenarios that did not occur. The notion that the fatality rate remained the same would imply no progress was made, which does not reflect the data from those years. Similarly, a worsening trend would indicate a significant rise in fatalities due to crashes, which would contradict the data showing improvement. Fluctuation would indicate a lack of consistency in either improvement or decline in the crash fatality rate, which again does not align with the findings that demonstrate a steady improvement.
