The Washington State Patrol has created an online database of all breath tests given to DUI defendants. You can find the database here.
Go down to the bottom of the page and click “Enter WebDMS.”Then click on “DataMaster search,” and you can browse the records.
It’s not exactly a breeze to search, however. You must know the “DataMaster” code — basically the location of the DUI breath machine — if you want to look up DUI results in a given period. But here’s one that I know: 140051. That’s the DataMaster machine in the Kitsap County jail.
The operator is the officer that made the DUI arrest. If you scroll to the right, “BrAC1” and “BrAC2” are the results of the two tests. Just plop a decimal point in front of the numbers (e.g. 123 becomes .123) and there you have it.
You cannot see defendant’s names here, only dates of birth.
This is interesting, but not too useful.
