The passive alcohol sensor is designed to offer a noninvasive method for alcohol detection. When that officer is removed from the analyses, there were no differences in arrest rates for the officers with the PAS versus the officers without the PAS in any round. Round 1 enforcement activities were conducted from June 2004 to July 2005, and Round 2 enforcement activities were conducted from October 2005 to February 2006 in Anne Arundel County, Maryland. At the conclusion of the data-collection period, a questionnaire was issued to each officer eliciting information about their general experience with using the PAS and whether they would continue using it. If drivers are aware that police are using the PAS during traffic stops, it could have a general deterrent effect on impaired driving [Voas and Layfield, 1983]. It can be used without the drivers knowledge and without any probable cause because the PAS is considered an extension of the officers nose and records information that is in plain view (Preusser, 2000). Designed to replace older technology and more expensive alcohol wands and flashlights, sometimes called alcohol sniffers, the FC5 Hornet is quiet and easy to use with new features never before available in passive alcohol screeners. government site. Table 3 shows those results. The PAS III uses a small, silent pump that draws an air sample through a fuel cell, generating a small electrical current in the presence of alcohol vapor. and transmitted securely. Any arrests, citations, warnings, and violations were recorded, along with the results of any evidential tests. The economical FC5 Hornet from Lifeloc Technologies is a new generation of passive alcohol sensor for use in environments such as schools, high visibility traffic enforcement, probation, jails, mining and related safety sensitive industries. This could be, for example, when the ambient observed phenomena are not available to a CCD camera during the night. You may have tried to quit on your own and it did not work. Detect and record BAC in real time and provide meaningful output. The site is secure. Following the field sobriety test, officers typically request a preliminary breath test (PBT) because experienced drinkers may perform adequately on the field sobriety test and still have high BACs. Thus, raising the perceived probability of apprehension is the most essential element of an effective DUI enforcement program. Only 3 of the 24 officers responding to the survey reported continuing use of the PAS (after the study). Alcohol. Lisa Aguila-Lemaster, the Impaired Driving Prevention Coordinator from the Office, provided project oversight and monitoring.
