The National Transportation Safety Board is recommending that all states, including Oregon, adopt a uniform blood alcohol content limit of 0.05 in an attempt to reduce vehicular deaths attributed to drunk driving. Currently, most states use the cutoff of 0.08 as the blood alcohol level that indicates a driver may be driving while intoxicated.
The NTSB contends that alcohol consumption sufficient to raise a driver's blood alcohol content, referred to as the BAC, to 0.05 is enough to lower most drivers' ability to focus on the road and make rational decisions while driving. The NTSB's recommendations are not mandatory, NTSB makes suggestions that legislators may consider. Drunk driving contributes to over 30 percent of motor vehicle fatalities in the United States per year.
