THC is the main psychoactive ingredient in marijuana. In Washington State, a driver under 21 years of age may not drive with a THC level greater than _____ nanograms per milliliter of blood.

  1. 5

  2. 10

  3. 15

  4. Zero

The correct answer is: Zero

In Washington State, drivers under 21 years of age are not allowed to drive with any level of THC in their bloodstream. This is because THC is the main psychoactive ingredient in marijuana and can impair a person's ability to drive safely. Even a small amount of THC can affect a person's judgment, reaction time, and motor skills, putting them and others at risk on the road. Therefore, options A, B, and C are incorrect because they suggest a limit for THC in the bloodstream, which is not allowed for drivers under 21.
