Washington Drivers Back Lower BAC Limit After Survey Insights

A recent survey conducted in Washington has revealed significant support for reducing the legal blood alcohol concentration (BAC) limit for drivers from the current level of 0.08% to 0.05%. The study, commissioned by the Washington Traffic Safety Commission (WTSC) and carried out by DHM Research from November 1-8, 2025, involved 850 drivers aged 21 and older. Following the presentation of information regarding the impacts of alcohol on driving, support for the proposed limit surged from 54% to 71%, while opposition decreased from 34% to 25%.

Understanding Current Perceptions

The survey aimed to gauge drinking behaviors and perceptions regarding the current BAC limit among Washington drivers. Notably, 78% of respondents accurately identified the legal limit as 0.08%, with 82% believing that impairment can occur at levels lower than this threshold. It is essential to highlight that drivers can face DUI charges even with a BAC below 0.08%.

Prior to receiving detailed information about the proposed change, support for lowering the BAC limit stood at 54%, compared to 34% who opposed it. After being informed about research findings related to alcohol impairment, support rose significantly, indicating a shift in public opinion.

Key Findings on Impairment

The survey revealed that after learning about the effects of a 0.05% BAC limit, respondents expressed increased support for the change. Key points that resonated with participants included:

– Research indicates that regions lowering the BAC limit from 0.08% to 0.05% experience an average 11% decrease in alcohol-related traffic fatalities.
– Drivers aged 21-34 with a BAC between 0.05% and 0.079% are nearly five times more likely to be involved in a fatal crash compared to sober drivers.
– Studies show that driving performance declines by 25% to 55% at a BAC of 0.05%.
– Areas that have enacted lower BAC limits report fewer instances of impaired driving.

Mark McKechnie, the External Relations Director for WTSC, noted, “This survey shows that Washingtonians care deeply about creating safer roads and highways. Most drivers 21 and older already know that impairment begins before the per se legal limit of 0.08%. With this understanding, most people think it’s obvious that the limit should be lower.”

Demographics of Respondents

The survey sample was statistically representative of Washington drivers over the age of 21. Among the 850 respondents, 29% resided in King County, while 20% were from Eastern Washington. The age distribution showed that 62% were between 30 and 64 years old.

In terms of racial demographics, 62% identified as White, 13% as Hispanic/Latino/a/x, and 16% as other people of color. A significant 90% of respondents reported driving several times a week or daily, while 56% indicated they consume alcoholic beverages. Among those who drink, 84% reported having six or fewer standard drinks per week.

The survey also highlighted responsible behaviors; 75% of drinkers stated they often or always plan transportation ahead of time, and only 4% admitted to driving after consuming three or more alcoholic beverages.

Broad Support Across Demographics

After receiving information about the proposed 0.05% BAC limit, support transcended demographic boundaries, ranging from 65% to 78% across various groups. Opposition remained under 30% among all demographics, with higher resistance observed among men, those earning $150,000 or more, and regular alcohol consumers.
