Breath / Blood Testing In BUIs
The BUI statute, itself specifically sets forth all breath/blood testing requirements.

It shall be a violation for a person to operate a vessel while under the influence of intoxicating liquor or any drug.  A person is considered to be under the influence of intoxicating liquor or any drug if:

  1. (a) The person has 0.08 grams or more of alcohol per two hundred ten liters of breath, as shown by analysis of the person’s breath made under RCW 46.61.506; or
  2. (b) The person has 0.08 percent or more by weight of alcohol in the person's blood, as shown by analysis of the person's blood made under RCW 46.61.506; or
