Report Writing with the End in Mind: Surviving DUI Cross Examination

This session is a practical, courtroom-focused training that connects field documentation to testimony. Presenters will demonstrate how vague language, omissions, boilerplate phrasing, and unsupported conclusions in police reports are routinely used by defense counsel to create effective cross-examination and undermine credibility. Participants will learn how precise report writing can minimize defense "fodder," narrow the scope of cross-examination, and strengthen courtroom testimony. Speakers will address strategies for handling cross-examination and ways to work with prosecutors to ensure success. Real-world examples of poorly written DUI reports are analyzed alongside corrected versions, showing how to document the same facts in a clearer, more defensible manner.

  • Upon completion, attendees will be able to identify common report-writing deficiencies in impaired driving cases that create opportunities for effective defense cross-examination.
  • Upon completion, attendees will be able to apply clear, precise, and defensible documentation practices that minimize cross-examination risk and strengthen courtroom credibility.
  • Upon completion, attendees will be able to demonstrate effective strategies for responding to cross-examination by testifying consistently within the scope and language of their written reports, and to work with prosecutors to give a clear and convincing presentation to the trier of fact.
