In Washington state, it is illegal to drive with more than 5 nanograms of THC or more in your blood if you are 21 or older. It is completely illegal for drivers under the age of 21 to have any THC in their blood.
If you are found to be over the 5 nanograms limit, you will be charged with a DUI, just like a DUI you would get for driving drunk. If you are charged, you will need an SR22.

An SR22 is an addendum to your auto insurance which proves to the state that you have the minimum liability insurance required by state law. The SR22 is a marker of a high-risk driver and can be issued for any major traffic violation besides a DUI.
