Superintendent's Compendium (425 KB pdf)

With the "routine use exception" to the Privacy Act which is now in effect, all or most of a MVA report may be made available upon written request by parties designated in that routine use exception; for example, individuals involved, injured, or who suffered property damage in such incidents, their duly verified insurance companies, personal representatives, or attorneys. The revised NPS-19 provides that information on MVA reports may be released to parties designated in the routine use exception only when the release will not interfere with an on-going law enforcement proceeding, risk the health or safety of an individual, or reveal the identity of an informant or witness that received explicit assurance of confidentiality. Report requests will be filed with and become a permanent part of the original report.
