It is illegal to drive with a BAC of .08 or higher in Arizona. Yet, over the 2015 Fourth of July holiday period (6 p.m. July 2 to 5:59 a.m. July 6), 146 people were killed in crashes involving at least one driver or motorcycle operator with a blood alcohol concentration (BAC) of .08 or higher, and 92 people died in crashes involving at least one driver or motorcycle operator with a BAC of .15 or higher – almost twice the legal limit.
