Every year highway law enforcement officials keep data about deaths that happened because of car or truck
accidents. These accidents are divided into three categories. The categories are:
. "no alcohol" (blood alcohol level is 0).
"some alcohol" (blood alcohol level is between 0 and 0.08), and
• 'alcohol impaired" (blood alcohol level is 0.08 or higher)
