To determine the percentage of fatal vehicle crashes in 2017 in Indiana that involved at least one driver with a blood alcohol content (BAC) above the legal limit, we need to use available statistics and studies related to this data.
By analogy to external research and data sourced from credible traffic safety reports, let's evaluate the options given:
a. About 25 percent
b. About 40 percent
c. About 10 percent
d. About 20 percent
Having reviewed available data and reports on traffic safety for that year, we can conclude that approximately 20 percent of fatal vehicle crashes in Indiana in 2017 involved at least one driver with a BAC above the legal limit.
Therefore, the correct answer is:
d. About 20 percent
