Concerning impaired driving.

Washington State's SB 5664 lowers the legal blood alcohol concentration (BAC) limit for driving under the influence from 0.08 to 0.05. The bill amends statutes (RCW 46.61.502 and 46.61.504) to establish 0.05 as the threshold for DUI charges based on breath or blood test results within two hours of driving. It also updates provisions related to THC concentration limits and evidence rules for impaired driving cases. This change directly affects all drivers in Washington who operate vehicles while impaired by alcohol or drugs, aiming to align with global safety standards and address rising traffic fatalities linked to impaired driving.
