Under 21, what is the legal limit for THC in blood in Washington State?

• A. Zero
• B. 3.00
• C. 4.00
• D. 2.00

Answer: (A)

In Washington, drivers under 21 face zero tolerance for THC in the blood. This means that any detectable amount of THC while operating a vehicle is illegal, regardless of how you feel or whether you think you’re impaired. The goal is to prevent underage impairment by making the threshold for a DUI 0 ng/mL for those under 21. So, the legal limit is zero. For adults 21 and older, there are separate, measurable limits, but that isn’t what this question asks.
