We love to celebrate the 4th of July with family, friends, food, and fireworks, but all too often the festivities turn tragic on the nation's roads. The fact is, this iconic American holiday is also one of the deadliest holidays of the year due to drunk-driving crashes.

Over the 4th of July holiday period in 2015 (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.

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.
