In Washington State, you can be arrested for driving with a BAC of ______ or above.

• A. 0.02%
• B. 0.08%
• C. 0.04%
• D. 0.06%

Answer: (B)

In Washington, the key idea is that there is a specific BAC level at which driving becomes illegal per se. For the general, non-commercial driver, that threshold is 0.08 percent. Reaching or exceeding 0.08% BAC means you can be arrested for driving under the influence even if you don’t show obvious signs of impairment, because the law assumes impairment at that level. There are lower limits for other situations (for example, commercial drivers have a 0.04% limit), but the standard limit for most drivers is 0.08%. So, a BAC of 0.08% or higher is the point at which a DUI arrest is legally supported in Washington.
