Notes:

  1. In 2005, Congress enacted the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU). Section 2007 amends the alcohol-impaired driving countermeasures incentive grant program to encourage states to adopt and implement effective programs to reduce traffic safety problems resulting from individuals driving while impaired by alcohol, including a program for high-risk drivers with a BAC of .15 or greater. A qualifying state may use these grant funds to implement impaired driving activities in accordance with the federal statute.
  2. States that have passed laws requiring more serious sanctions for drivers convicted of a DUI/DWI offense if their BAC at the time of arrest exceeds a certain level (.15+, .18+, .20+). These sanctions include a longer jail sentence, a longer license suspension period, mandatory alcohol assessment/treatment, and/or a steeper fine.
