Abstract
This Guidebook is dedicated to those public safety professionals who tirelessly study the myriad of issues surrounding impaired driving and search for answers to solve the problem of impaired driving that exists today. However, too often lost in the active search for answers are the unsung heroes of this ongoing battle. It is the state, county, city, and Tribal law enforcement officers who perform the often unrecognized work of removing from our roadways those who would endanger us by driving impaired. It is for their efforts that we offer our undying gratitude and support and dedicate this work. (Author/publisher)
