Welcome to WebDMS

The Washington State Patrol is delighted that you have found this resource. This is being provided to make comprehensive information concerning records of breath test results, instrument maintenance, policies, procedures and manuals of the breath test section of WSP instantly available to the courts, the public and the criminal justice community.

The records that have been posted on this site are among those most frequently requested by the defense bar in litigation of impaired driving related issues. The purpose of providing them in this format is to make them instantly available, without the delays often inherent in the normal discovery and disclosure process.

We believe that this is the most comprehensive database of its type available anywhere in the world for this type of information, and we look forward to seeing it used to improve the efficiency and thoroughness of legal discovery in this area.

Please contact the Breath Test Program of the Washington State Patrol at 206 720 3018 if you have questions or problems in the use of this web site, or suggestions for its improvement.
