It is the responsibility of law enforcement officers to detect and arrest alcohol-influenced drivers in accordance with statutory limits. In an effort to meet that objective, police officers, not only in Florida, but in all fifty of the United States, rely on a battery of standardized field sobriety tests (SFSTs). Observations of drivers' performance of the tests, together with driving pattern, appearance and manner, odor of alcohol, and other signs, underlie officers' arrest and release decisions. To be genuinely useful, roadside tests must be valid and reliable; i.e., they must measure changes in performance associated with alcohol and they must do it consistently. To the extent that they meet the validity and reliability criteria, they can be expected to contribute to traffic safety by increasing the likelihood that alcohol-impaired drivers will be removed from the roadway by arrest. Importantly, they also will further serve the driving public's interests by decreasing the likelihood that a driver who is not alcohol-impaired will be mistakenly detained or arrested. Thus, the validity and reliability of the tests are important issues. This study was undertaken specifically to extend study of the SFSTs from the laboratory setting to field use. The primary study question was, 'How accurate are officers' arrest and release decisions when the SFSTs are used by trained and experienced officers.' |
