About Forensic Sobriety Assessment

FSA promotes the competent and objective appraisal of scientific evidence regarding field sobriety testing and provides training and certification to professionals involved in DWI / DUI enforcement. FSA recognizes the serious problem of intoxicated drivers, as well as the large financial and personal costs that can accrue from an incorrect arrest.
