Are my DUI breath test "maintenance" records online?

Yes, the Washington State Patrol (WSP) maintains a web page with all the pertinent records including maintenance on your specific breath test machine for your DUI arrest anywhere in Washington State. You need to know the number of your machine (BAC Datamaster) and date of your arrest. The number is typically  listed on the second line of your breath test ticket. See link: WSP Breath Test Records.  Alot of good legal issues can come out of reviewing these records.
