About Drunk Driving

In Idaho, a blood alcohol content of .08 or above is considered impaired, and legally drunk. According to the National Highway Traffic Safety Administration, all 50 states have now passed .08 BAC laws for impaired driving. An NHTSA study shows nearly 97% of Americans view drinking and driving by others as a threat to their families and themselves. The study found Americans rank drunk driving ahead of healthcare, poverty, the environment and gun control as an important social issue. The majority of Americans support increased enforcement efforts, according to the NHTSA.

National statistics show 40% of those killed in auto accident are involved in alcohol related crashes.

  • Plan to spend the night where the activity is held.
  • Serve non-alcoholic beverages at your gathering.
  • Report impaired drivers immediately to your local law enforcement -  call 911.
  • Always buckle up. Seat belts are your best defense against an impaired driver
